Suggested by Jean Demitri Maximoff is a powerful vampire who can fire off energy blasts and has some good speed. He’s well known for hypnosis but that’s not going to work on Thor. Thor’s mighty Mjolnir will lead him to victory here and his raw power is far greater than Demitri’s. Thor should also be able to keep up in speed even if Demitri has the slight edge there. Ultimately Demitri isn’t as balanced a fighter and will fall here. Thor wins.
