1. Jack Bauer -

Where in the world do you start with Jack Bauer? First of all he is the best TV character of all time, barring no one, with Kiefer Sutherland being the best actor ever. Jack suffers tragic loss and extreme pain and torture (as well as inflicting some himself) takes out the bad guys and saves the world from horrific terror attacks, all in 24 hours, time after time! He is very loyal, shows no mercy and looks awesome with a gun and sunglasses. He is a modern superhero who is unforgettable. Plus he's the one character you never have to worry about dying, no matter how much danger he's in. In addition to everything else he had a wife Teri who was murdered by his partner and has a daughter Kim and granddaughter Teri. In case you haven't realized it, I love Jack Bauer and will forever!

Days: All, 24 isn't 24 without Jack Bauer, no matter what anyone ever says.

Played by: Kiefer Sutherland.

2. Tony Almeida-

Tony Almeida is a spectacular, tough and yet emotional character, who is amazing, but can't top Jack Bauer. He is awesome in his own way, but he isn't as uncaring (at times) and sacrificing like Jack. He cares for his family and friends more than anything and would go to jail to keep his wife safe (which he did) He was Director of CTU a few seasons as well as being an experienced agent, who hasn't always been so lucky in his personal life.  Tony is memorable in many ways, one of which being how he usually whispered (or muttered) his answers, "Yeah" or "Okay". Tony is a strong guy who has been Jack's right hand man and always had his back, although sometimes his personal issues took priority, especially when it concerned his wife Michelle.

3. Chloe O'Brian-

Chloe O'Brian is another wonderful character who I think is just as good as Tony Almeida which is why she is tied with him in my opinion. She is a senior data analyst, the best and a total computer whiz as well as being someone you don't want to match wits with, because you will lose, no doubt about that. She is extremely loyal to Jack and would do just about anything to help him out. She is remarkable for being one of the few survivors and at the end of Season 8, she wasn't on the wrong side of the law and had a top-notch government job. She's married to Morris O'Brian and has one son. In LAD we have a changed Chloe O'Brian, but she still is awesome! She is known for her grumpy 'Chloe face' and is one of the most loyal, most sarcastic characters you will ever meet.

4. David Palmer-

David Palmer is one of the most upright and moral characters who is President in Season 2 after multiple assassination attempts in Season 1 which were foiled by Jack Bauer with the rest of CTU assisting.He is also loyal to Jack and not only helped him fake his death but will always listen to Jack when the CTU agent needs assistance. He has two siblings, Wayne, who will also become president and Sandra Palmer. He also has a politically ambitious ex-wife Sherry Palmer and two children Keith and Nicole. He is a great guy who you know will make the right decisions, no matter how tough they can be.

5.  Michelle Dessler-

Michelle was introduced in Season 2 as working for CTU and just got better, becoming one of Jack's closest and most trusted allies  as well as one of his closest friends outside of work in addition to being director of CTU for a while. She married Tony Almeida between Seasons 2 and 3 and both would go through many harrowing circumstances in which they had to make hard decisions for the other and for themselves. Eventually both left CTU to start a new life together, relatively free of stress and worry until Michelle's tragic death in season 5, launching her husband into action to get revenge for people who engineered the death of his beloved wife. I love Michelle because of her great leadership abilities, her relationship and friendships and her loyalty, among other things.

6. Morris O'Brian-

Morris O'Brian is married to Chloe O'Brian and is similar to her in many ways, also being a smart CTU data analyst and sarcasm being a strong point for the both of them. Morris O'Brian is a lovable guy, who might give his superiors a hard time, but is unwavering in his devotion to Chloe, even if he is skeptical of some of Jack's plans. Overall he is a great agent and good comedic relief for when the days become stressful.

7. Sherry Palmer-

You never quite knew who Sherry was loyal to, except herself, maybe it was always just to herself. In Season 1 she is the wife of then Senator David Palmer and seems to be a beautiful and supporting wife and mother who had a great touch. Nope, she turns out to be a politically ambitious woman, who will put herself being in the White House and being a key staff member above all else. She was willing to destroy documents, go behind her husband's back, and put him and Jack in danger, all for power. At the end of that first stressful day, David divorces her, realizing he can't trust her, much to her mortification and anger. She doesn't leave the political realm though and comes back for revenge and power, although she does help Jack at one point, after all her mistakes (or crimes) have been revealed. Eventually Julia Milliken, whose husband Sherry let die, kills her before turning the gun on herself, all in front of Wayne Palmer's horrified eyes. Sherry is just so awesome to watch and one of the writer's biggest mistakes was killing her in Season 3. Imagine her vs Logan after David's death in Season 5, now that would've been AWESOME to watch!

8. Renee Walker-

Although she is introduced later in the show (Season 7) FBI Special Agent Renee Walker quickly becomes a strong, unforgettable character. Although she disapproves of Jack's "the end justifies the means" tactics at first, she eventually goes as far as he does and has been referred to as the female Jack Bauer who will do what she needs to get the job done, which eventually got her fired from the FBI. She later resurfaces in Season 8 as broken woman who attempted to commit suicide and yet she is willing to work a dangerous undercover mission for her country. She and Jack have a special relationship and had each other's backs during the eventful days. I love her so much, she is just that awesome and she and Jack made a great couple, perhaps the show's best.

9. Nina Myers-

Ah, Nina the infamous mole who killed Jack Bauer's wife Teri and put his and Kim's life into a tailspin that they never fully recover from, Remember her? Oh yeah, and on top of all that she was selling classified information to the highest bidders, including plans of CTU so it could be blown up later. She starts out in Season 1 as second in command under Jack and being his partner and pretty much she is the only one he trusts. She helps him, was involved with him when he was separated from his wife, and seemed to care for his wife and daughter. Turns out she's been playing him, Tony (with which she was involved romantically) and everyone else at CTU for a long time and is really an evil traitor who tried to have Jack killed. After that she appears in various episodes throught the later seasons until Jack killed her in Season 3. Nina is deceptive, cool to watch and and an unforgettable, developed, amazing villain. I also love the actress Sarah Clarke, who met and married another great actor (Xander Berkeley) when she was on 24.

10. George Mason-

Somewhat out for himself and being blackmailed twice by Jack, George Mason is a brilliant Director who has a nasty habit of doing the right thing in spite of himself. In Season 1, he is anti-Jack, especially after Jack shot him with a tranquilizer dart so he could get some information. In the beginning episodes of Season 2 George inhaled weapons grade plutonium and doesn't have long to live, becoming this great and memorable guy who gave his life instead of Jack, by piloting a nuclear bomb into the desert, a suicide mission after telling Jack one of the best 24 quotes (in my opinion) "Come on, Jack, you've had a death wish ever since Teri died. The way things have been going for you the past year and a half, this probably doesn't look like such a bad idea. You get to go out in a blaze of glory, one of the greatest heroes of all time, leave your troubles behind. You still have a life, Jack. You wanna be a real hero, here's what you do: you get back down there, and you put the pieces together. You find a way to forgive yourself for what happened to your wife. You make things right with your daughter, and you go on serving your country. That'd take some real guts." One of the most emotional scenes ever is where he brings his estranged son John into his office and tells him he's dying and how sorry he is that he wasn't always there for him. Later he also encourages Michelle to follow her dreams, all this while he is dying serving his country by trying to prevent a nuclear bomb from going off in LA. I love his snark, all his lines and his courageousness when it really mattered.

11. Edgar Stiles-

Edgar Stiles was a lovable tech analyst who was a big help to Chloe on multiple occasions  and became her best friend. In Day 4 when nuclear plants were melting down and his mother was at risk, he was willing to risk it all for her, being loyal to family and friends above all, such as Chloe who is also loyal to him, even when she lost her job when then director Erin Driscoll found out Chloe was assisting Jack, Chloe never implicated Edgar. Although he was a geek he knew what the right decisions were and you could count on him. Unfortunately all that made his death (called one of the most sad deaths in 24 history) all the more heartbreaking, when Sentox nerve gas came through the air conditioning of an infiltrated CTU and he was one of the agents not in an airtight room, leaving Chloe devastated and blaming herself for his demise. Edgar is a sweet loyal teddy bear, and a great analyst whose death will always haunt me.

12. Mandy

Mandy is super awesome, even if you didn't see her all that often, not to mention she is a professional assassin for hire that participated in trying to kill David Palmer, twice! She is smart, pretty and extremely deadly (Just look at Martin Belkin!) She helped Ira Gaines in Season 1 to try to assassinate David Palmer and then tried to kill David Palmer again in Season 2 and finally kidnapped Tony and killed another agent in Season 4, after being involved with Habib Marwan's schemes. She was making a deal last we saw her, but as far as we know she is still alive to return and cause more trouble for Jack Bauer and company! I love how relentless she is and she blew up a plane to kill a man (which was so freakin' cool!)

13. Bill Buchanan-

Bill Buchanan may not come in under the best circumstances or at the best time. But he becomes a great Director (Can you tell directors change a lot?!) and is a good moral compass. He trusts Jack implicitly and eventually gave his life for him and for his President. He is married to Karen Hayes who is involved with Homeland Security and then as a trusted adviser to President Wayne Palmer. He risks a lot, is committed to making sure his country stays safe and realizes Jack is usually the answer.

14. Curtis Manning-

Curtis Manning is a field agent like Jack and stuck around 3 seasons which is longer than most. He was a great agent, and although he doubted Jack's capabilities and was at times jealous of him, especially when Jack came back to CTU and was elevated to Curtis' place (Director of Field Operations) and Curtis was demoted, Curtis always did what was right and did it fantastically. Eventually Jack and Curtis learned to work together and were a great team until Curtis sort of lost it, when CTU was working with a former terrorist and Curtis tried to kill him, because this man, Hamri Al-Assad had engineered an attack that got his teammates (In a former operation) killed, but Curtis died instead.

15. Audrey Raines-

Audrey Raines is the daughter of Jack's boss in season 4 Secretary of Defense and later President James Heller. Jack was also romantically involved with her until the end of Season 6 when he learned she had tried to rescue him from the Chinese and had gotten captured herself, eventually he got her back at the end of Season 6, only to realize she was extremely traumatized after being severely tortured by the Chinese. She was a capable and very beautiful woman who assisted during Days 4 & 5. In Season 4 she  and her father had been kidnapped, to be rescued by Jack. She has an ex-husband Paul Raines, who took a bullet for Jack, her father (already mentioned) and a brother Richard. In the half season she is married to her father's Chief of Staff Mark Boudreau, after everyone thought she and Jack had a real chance. I like Audrey because even with all that has happened to her, she fought her way back and became an even better woman.

16. Kate Morgan-

Kate Morgan is my favorite new character added in 24: Live Another Day, in addition to being the only one to make it on this list. She is also similar to Jack Bauer (she's a field agent too) and thinks like him. She almost catches him more than once as a capable CIA agent before she sides with Jack and gains his trust, and along with Chloe and Jack, she stops Margot Al-Harazi and Cheng Zhi from carrying out their nefarious designs and tries to save Audrey. She is a great character with a lot of depth, it looked as if her husband was a mole and when he went to jail, he committed suicide because Kate didn't believe him anymore (it really was Steve Navarro) and she blames herself. She is almost fired, but is like Jack in the way she stays on with a "I'm the only one who can do this" situation. She and Jack become trusted partners and risk their lives to keep London safe. She has the same great attributes of Renee and Jack and that's why I love her. (Even if she was just in a half season) Plus she's still alive!

17. Wayne Palmer-

Wayne Palmer, brother of President David Palmer, first came on the scene in Season 3 as Chief of Staff, following Mike Novick's (I call him Turtleface) betrayal in Season 2. He is a somewhat different from his brother, being more reckless and willing to cover some things up, a bit like his sister in-law, the difference being he is loyal to David and will acquiesce to his decisions, whether he likes them or not. Based on that, you would have thought he would be more independent during his own presidency, but he relied too much on his advisers, one of the only good things he accomplished was negotiating Jack's release from the Chinese, whose embassy the agent had infiltrated. Overall he is a good character, his family being siblings David and Sandra, sister in-law Sherry and niece and nephew Nicole and Keith, respectively. I really liked Wayne, especially in Season 3 and 5, although he did well in 6.

18. Chase Edmunds-

Chase Edmunds is probably the most underrated 24 character ever. He only appeared in Season 3, although he was alive and went to on continue dating Kim Bauer, Jack's daughter who worked at CTU at the time. He has been described as a younger, more level-headed Jack. In Season 3 he is Jack's partner on the field and is a great assistance. When Jack broke Ramon Salazar out of prison in order to go back undercover, Chase was kept in the dark and went after Jack, only to be a part of a test in which Jack passed, willing to shoot his partner.  (Chase then thought Jack had gone over to the dark side) He then was tortured but escaped with Claudia and her family, he then tracked Jack and watched his meeting. Unfortunately, he was strapped to a bomb and had to have his hand cut off (it was reattached) and left to start a life with Kim and Angela (his daughter from a former relationship) his and Kim's relationship ended when he couldn't take Kim's grief when she assumed Jack dead. He is a strong, determined character and was like Batman's Robin. It is extremely regrettable 24 didn't keep him as he would have been a great permanent addition to the show.

19. Kim Bauer-

Kim Bauer, who like Jack makes her own rules, is 24's own damsel in distress. She starts off in Season 1 by playing chess with her dad, Jack Bauer and then slighting her mother Teri Bauer. She sneaks out to go party with her friend and the guys kidnap Kim and her friend Janet York for a man named Ira Gaines, who is trying to get Jack to drop the case. Kim gets kidnapped multiple times and goes to jail because of a misunderstanding, all in a day. Her mother goes out looking for her and gets kidnapped too and eventually both are rescued and more bad things happen. In Season 2 she doesn't want anything to do with her father after her mother's murder, she rescues a little girl from her abusive father and tries to escape LA, only to be arrested and then escape, have a close shave with a cougar and...yeah you get the picture. In Season 3 she works for CTU and helps solve the days' events as well as date Chase Edmunds, a field operative under her father. At the end of the season she leaves to try to start a life with Chase, which fails. During season 7 she is married to a man named Paul Wesley with a daughter Teri (named after her mom) after pushing away her father for so long after she learned he faked his death, she reunites with him in Season 7 as it looks like he is dying. At the beginning of Season 8, Jack is about to move back to LA with Kim's family, but is sucked into the day's events. I like Kim because she is Jack's daughter and although she goes through a lot, she comes out on top in the end.

20. Mike Novick-

'Turtleface' himself has also been around since Season 1 as David Palmer's original Chief of Staff. Even though he later betrayed David Palmer to accomplish what he thought was best for the country, he makes reappearances, such as being later President Charles Logan's chief of staff. He reminds you of a turtle, but he is overall a pretty good guy and advisor to multiple Presidents. Mike is an amazing, yet sadly underrated character, whom I really enjoyed.

21. Aaron Pierce-

Secret Service Agent Aaron Pierce is one of the best. He is conscientious and willing to protect all under his charge, usually at risk to his own life. He also first makes an appearance in Season 1 and is in charge of protecting David Palmer, then later the despicable President Charles Logan, whom he helps expose, later he was involved romantically with Charles Logan's now ex-wife Martha who hates her ex-husband venomously and helped implicate him and cause his arrest with the help of Aaron Pierce and Jack Bauer. Aaron's final appearance (although he doesn't die) is protecting Olivia Taylor and eventually bringing her to justice.

22. Martha Logan-

Martha Logan is the wife of President Charles Logan. She is extremely emotional and has mental issues. She was a really good friend of President David Palmer and can never forgive her now ex-husband for what he did. Charles also had beat up Aaron Pierce and almost killed, as well as trying to kill Jack and just aiding terrorists. She helped implicate him and tried to kill him in a later season (he was just put under house arrest) Worst of all though is he also gave Jack to Chinese torturers. He is the worst President in 24 and he tried to write off his wife, but she was determined to see him get justice for his multitude of crimes. During all this she also became good friends with the Suvarovs, who trusted her. Although she was seriously an emotional train wreck, she had her great moments! Plus she had some of the GREATEST lines of Season 5!

23. Dina Araz-

Dina Araz and her family were a cell of a terrorist group in Season 4 led by Habib Marwan. She was fully invested in the terrorist plot and making sure it worked, until her husband arranged to have their son Behrooz killed, because he didn't think Behrooz believed enough in their cause. But Behrooz got away and he and Dina ran off. Dina was in need of medical assistance because of an arm bullet wound which she got while escaping. Eventually, CTU found them and Dina told them everything in exchange for immunity for her son. She tried to help Jack undercover, but was tested and failed the test by not shooting Jack Bauer. She unfortunately died because of multiple bullet wounds after she failed the test. I will always remember her saying Behrooz though! I enjoyed this mysterious and somewhat unpredictable character. Shohreh was PERFECT for this role and no one could have played Dina better than she did.

24. Kate Warner-

Although some don't like her, I really liked her and wished she had had a reappearance beyond Season 2 and the a few seconds in Season 3. She cared for her sister and didn't quite trust Marie's fiance, so she checked him out and found he apparently had dealings. She was always unselfish and did what she needed to do to protect her family and those she cared about, even when her sister was revealed as the terrorist, she did what was right and helped Jack, even while loving her sister. I'm not sure about her and Jack together, but I loved the character, who seemed to grow and become a great character by the time she stood by her father before Marie was transferred to CTU. Kate Warner is one of the best characters who never got enough time in 24, even if she left the series alive (a rarity, as all 24 viewers know).
