Kayako -The Grudge
A lot of people may not immediately assume this Japanese ghost is a heavy hitter in the horror world, but rest assured, she might be the most fearsome foe any Marvel hero could tangle with. Kayako may not be physically strong, but she can teleport, has super speed and can paralyze and possess whoever she damn well pleases. Oh yeah, she also reads minds and warps reality. It’s basically like you’re dealing with the Phoenix Force, except the Phoenix Force has been defeated by Marvel heroes. Kayako hasn’t lost, and with no clear way of defeating her (unless low cinema scores do the trick), I’m not sure there’s a Marvel hero who could take her down either.
