Not really battle board related I suppose. At least not directly, but since Ultron is a constant contest in many fights here I though I would post this. Apparently Ultron is making his return in Mighty Avengers. Great news right? Well Ultron is no longer a he.
In light of this a few Ultrong fights:
Ultron vs New Avengers
Ultron vs X-men (current line up)
Ultron vs Cable and Deadpool
Ultron vs Magneto (I know, its funny)
Ultron vs Doom
Ultron vs Dr. Strange
Ultron vs Supergirl
Ultron vs JLA
Ultron vs Superman and Wonder Woman.
Ultron's brain patterns are based on Hank Pym, who has never shown any signs of gender issues, why would he suddenly become a female? Like someone said, they already had a female Ultron, Alkema, they could have just created a new version of her with new brain patterns.
