A witcher!

Basically what if the guy Goku what's to punch is the people who made him anti magic human. I doubt he could have done that augmentation all by himself but you never know. And I really hope wasn't experiment as a kid making him a child super soldier like a witcher.

That or he has grudge with the world hater magik thus why he will join the fight.

Also you guy think anti magic material could exist in this world like to deal with Witches who have gone rogue.
