You're right, Kadaj ! I too am pissed off when I read HP characters' names badly spelt !

Beacause he's able to use the strongest magic in the world; LOVE... ;3 <3

Dumbledore

bellatrix is probably the most powerful witch

She is I can go on bout this but I rather save it for an article

and Bellatrix for sure:)

i picked voldemort because harry is powerful because of him , if harry's parents where never killed harry would be the same as every body else

lived the longest,is the wisest and as McGonagall put it "he is too noble to use" his powers.though mistakes from past help

Potter is lucky, not powerful.

DUBELDORRRRR

Snape?

Voldemort and Dumbledore are the most powerful wizards
Snape is quite skilled too but not on the same level with them

Most powerful witches in the series are Minerva and Bellatrix I'd say but both of them also not quite a match for Voldy or Dumbles

Potter isn't powerful at all...he's just been lucky and had talented people that helped him and died for him
(his parents,Dumbledore,Snape,Sirius,Mad-Eye,Lu­pin­...­.)

its definitely dumbledore, here's why
ok harry is sort of out of the picture cause well, he was mainly only powerful because of the fact that when he accidentally made a horcrux out of harry some of his power got transfered to harry. so thats why harry is powerful, i mean i'm not saying he is not brillant but other things such as the charm his mother placed upon him and with dumbledore protection which helped him in defeating voldemort plus also the help of his best friends without whom he could not survive to add on also his power to love which voldemort does not have. so i would not say harry is totally powerless, he is slightly lower than equal with voldemort.

we all know that both dumbledore and voldemort are powerful wizards but voldemort was always afraid of dumbledore for a reason, and thats because dumbledore could see right through him and as he did not like to feel vulnerable, he did not dare to attack when dumbledore was around. this also proves dumbledore's power. also voldemort had nothing to fight for so therefore, did not give him much of an agenda.
