I've been watching a lot of Death Battles on www.screwattack.com/ lately and I thought that they should have the Ben 10 from Ultimate Alien fight someone. But I don't know who would be his perfect opponent. Any ideas? (Please no one say Superman)
How about Naruto? He's extremely versatile, has good level of strength and summons to keep up with stronger aliens, is already possesed and trying to contact his mind annoys kyubi. Though he can be too strong, no idea, but They can have a good fight, specially because screwattack loves to make nice looking ones..
