Imma say Doomsday since he could actually attack and is destructive. How can the user attack if all they do I put their immutability on someone else?

Rare abdalla not choosing the random user with an overpowered ability? Woah..

Wait, they could reflect the damage back to Doomsday......oops I messed up

I find it funny how ironic my interest in this character compared to most users here who likes Superman, yet I hate Superman, but love Doomsday.
