Ok, I just got a box of S.H. Squad books and my daughters put two teams together of 6 each.
Two battles, the first is Squad vs Squad and the second, (since I don't watch enough Superhero Squad) regular M.U. versions. I think it might actually be a decent battle......if Surfer can't use his full spectrum of powers putting him on the same level of the rest of them......strength, invulnerability, flight, basic power blasts, etc. Not "Odin force" Thor either.
Captain America, Thing, Hulk, Ms. Marvel, Invisible Woman, and Spider-Man
Iron Man, Reptil, Silver Surfer, Falcon, Wolverine, and Thor.
Squad battle is in Super Hero City for a charity show put on by the mayor for his election campaign.
Clean fight in character for the Squadies. In a park.
M.U. battle in character, morals on (no speed blitzes etc.) but know they have to win for personal reasons put forth buy the .....Grandmaster....cause I lack further imagination :(. Takes place in an already devastated city with no population. Grandmaster gives them two hours prep time to scout the area and find/build equipment and prepare plans. They know their opponents.
