They've met in the comic, Sonic and the black knight and Sonic Generations (The olympic games doesn't count).
They're friends in Sonic and the black knight and Sonic Generations
It's said Shadow has feelings for Blaze in the comic. But since it's not created by Sega, it doesn't really count.
But Shadow can start liking her. He has met her and they have things in common. So it's possible that Sega will put Blaze with Shadow.
I'm tired of people who talk nonsense (I dont want to disappoint you). but need to tell the truth. coz some people (like Silver12345) have wrong things about sega and blaze pairing.
but first- if you so sure of your pair. there is no need to scream SILVAZE or another ! ! ! this opinion is better to keep to yourself. As well as other. and most importantly do not lie and lead others astray. using silly words...
1- Takashi Iizuka the one who established the concept of the story in the Sonic franchise. (((link)))
Since 1998 (from sonic adventure) to the present day.
He created "TERIOS" (shadow and blaze first original appearance and theirs second name) (few fans know about it) (((link)))
but after the game "Shadow the hedgehog" (his favorite character) which did not like the public (the game). in Sega decided that the next project (sonic 06) should be entrusted to another person. Shun Nakamura!
2- Shun Nakamura !!! (((link))) the Silver`s creator and also Sonic 2006 directed by him.
And as he said in an interview (he liked Silvers`s naivety) YES
He is the author of blaze words. "you are so naive" and the last sentence of blaze "I`ve always liked that about you" to silver.
Though it is not love. this is a high degree of sympathy. and Yes, with romantic music he tried to make Silvaze. "But its no use"
As explained later Sega "Blaze homeworld is the like as Silver's and the two share a brother-sister relationship"
After epic fail of sonic 06. Shun Nakamura fell in the post as director of sonic games. and since 2010 had no effect on the game of Sonic. and never will be (
since 2010 still unborn - silvaze dead... X(
3- Later, when Sega realized that the failure of the game Sonic 06 is much worse than shadow the hedgehog. in 2008 Takashi Iizuka became the head of "Sonic team".
Takashi Iizuka still being chief producer of Sonic games.
justice has been done....
4- At Sonic Boom 2012, Iizuka has confirmed that Blaze is in fact from the Sol Dimension, not from the future!!!!! Yeah. it means history of Shun Nakamura noncanonical bullshit.. sonic rush is 100% canonical !!!
- REAL hints at sonaze available in Sonic and the Black Knight (when the blaze was too shy and blushed from Sonic) and Sonic rush (I just cant explain that. you must play this game or see this link) after 2009 was no hints about Sonaze.
- shadaze proof in the comics. also in sonic generations Shadow standing next to Blaze (closer than Silver)
I mean he can stay anywhere (with rouge, Chaotix team or just alone) but still with blaze. strange isn`t?
- In mario and sonic 2012 olympic games heve hints too (have real hint about Sonamy)(link)
To be honest its probably just an opinionised thing. It doesn't matter which one is better, I think that Sonic shipping should be what you want. If you want Blaze to be with Silver, Blaze can be with Silver etc. So, yeah...
Maria is Shadow's human companion, She's also a Love Interest for Shadow, while Rouge only helps Shadow and she works for the G.U.N (Guardian Units of Nations). If she follows their orders, she will be rewarded. The reward is her favorite thing....Jewels. Shadow and Blaze are just FRIENDS. While Silver and Blaze are best friends...Blaze talks to Silver more than anyone else...Shadow is too serious for Blaze. But all of us have different opinions, some of us says Shadow and Blaze love's each other while others say Silver and Blaze and sometimes Sonic and Blaze...But Sonic already belongs to Amy.
No, they do not. Shadow would probably remain single... forever. This is because Shadow really would not go for a relationship, thus, not doing anything romantic.
Blaze, I'd say, has Sonic. Silver and Blaze come from Sonic 06, which has been considered non-canon. Sonic runs AWAY from Amy, and it's not because of his "feelings", it's because she's SO DANG CLINGY. Blaze, on the other hand, is like the "Sonic" of her dimension. Fast-paced, loves to go on adventures, and is laid-back. And even in the ending of Sonic Rush and Sonic Rush Adventure, they kind of HINT at the little interest they have. (see embed video.)
So basically, no. Shadow and Blaze do NOT love each other.
