10 Harry Potter Characters Scarier Than Voldemort 

I think Aragog is the scariest of these, I'm not Arachnophobic, but he gives me the creeps.

Bellatrix. Talk about crazy

Several of those I didn't find scary at all. Dobby? lol

For me, the scariest is Dolores Umbridge. She is just one sadistic, bigoted, power-crazed, self-righteous bitch wrapped up in a hideous pink bow.

Araogg and his 37209562307561387 evil spider babies.

I am arachnaphobic as HELL and during the Forbidden Journey ride I nearly peed myself when Aragog popped out of the huge webs and sprayed water in my face.

Bellatrix Lestrange
Dolores Umbridge
the Dementors
(DOBBY!!!! who finds him scary??he is such a sweet elf)

Dementors, then Fenrir Greyback, then Bellatrix Lestrange, then Dolores Umbridge, and then Aragog.

But I don't understand how Dobby is scary! He's adorable <3

I absolutely agree with Fanfly. Umbridge is the scariest.

Dementors are scarier than Voldemort.But Dobby and Grawp???
