right, voldemort lieks to show off, we all know that, he always has his death eaters about him when doing some important evil thing
but gandalf, he has on his side the valar, and illuvatar (god)
now who would win that, plus gandalf would never die by one of voldemorts death spells, think back harry potter book five, mad eye moody says, the aveda kedaveda curse needs some real power behind it, all you could point your wands at me and yell the words and youd be lucky if i got a nosebleed, now, gandalfs power FFFFAAAARRRRR outreaches voldemorts, the spell would not effect him much, if at all
Yes, power behind it. Harry and the others were weak wizards and weren't used to using the spell. Voldemort, however, is used to using the spell and is very powerful. Gandalf being powerful has nothing to do with it. And even if it doesn't kill Gandalf, Voldemort could just turn him into a rock or insect and crush him.
Gandalf the White is as strong as an istari can be.
I imagine Maiar aren't so easy to manipulate that way. Even Gandalf would not be so dependant on his flesh as a Harry Potter world wizard. Normally Maiar wear their flesh as a mere garment, but the wizards are more hampered by it than usual; this handicap was implemented deliberately by the Valar in council with Eru.
To be skilled with an Unforgiveable Curse, a wizard has "to MEAN them, to want to cause pain (or control, or death) to ENJOY it."
Harry could not use the Cruciatus Curse because he is not perverted like Umbridge is.
The reason that Voldemort was defeated by Harry the first time was because of love. The second time, the spell of love was still active. The third time, it was because their wands were brothers. Harry is still a weak wizard. Voldemort would win. Gandalf is in a mortal body, Voldemort is not. He's gone through many transformations and could possibly be immune to some magicks.
and also read the silmarillion it tells how he doesnt use his full powers, he is not allowed too
he could basically destrot middle earth or at least most of it if he wanted, but was forbidden to use his full powere incase of this, plus some of the spells gandalf does cannot be done by voldemort, and p.s voldemort is human, harrys human blood, see
he came back after the whole balrog thing. and besides, gandalf and voldemort are both powerful, but in differant ways. they are from differant worlds, so it's kinda hatd to tell what effect they would have on each other. Voldemort likes using his powers to hurt people, but gandalf doesn't, so what would happen in a duel between the two? voldemort could try to zap him with a hex or something, but gandalf is beyond little death hexes. he'd blow voldemort into the next year.
