@outside_85: I don't think Doomsday would survive without a head... By the same Token, I could argue the same thing for Hulk, but we both know that'd be a huge stretch. Yes Doomday had insane Regeneration, and yes, he got stronger, but to take it as far as comparing him to Hunter/Prey and saying he could survive without a head is just plain ludicrus. We both know if Diana beheaded him that would be the end of that. With at least three powerhouses EXCLUDING Hulk, each with a completely unique powerset all trying to take Doomsday's head off after realizing they can't beat him flat out, they would find a way.
@ajax1998: I mean she hasn't shown it, but she is a telepath, a telekenetic, and has ripped through Vibranium and disentegrated whole hordes of Bots. Put that all together, and it wouldn't bd hard to assume that at full power, morals off, she wouldn't just try completely destroy the monster through lobotomy. Either way, the message I was trying to get across is that Wanda is by no means a non-factor here, she is a real threat to Doomsday, and going all out, I fully beleive she has what it takes to do massive damage to Doomsday.
