Well a voodoo doll is suppose to represent the person you are trying to curse so now that doll is now unbreakable.

Sonic should use that thing as a weapon. He'd be undefeated.

While a funny picture I think there's an error with this picture. Notably the first frame shows his left hand holding the doll, and the next it's in his right hand

I thought voodoo need the victim hair to work which Saitama has none.

...on the top of his head at least. Which would lead to the question of how he got that piece of hair.

I thought you could use nails and blood too? Or anything belonging to the person?
