I need two teams of Super Heros and Villans that fought in WWII for an Allies and Axis war. My map would be LoSH Small Town - Outdoor (but if you can sugest a differant one let me know)

Well, for DC, you can use a figure with the "All Star Squadron" keyword. Also, Sergeant Rock and any of the Easy Company figures all fought for the good guys. The three Blackhawks figures also fought in WWII.

For Marvel, you can use the Invaders keyword to give you some of the WWII good guys. The HYDRA keyword can give you some bad guys, led by Red Skull, Arnim Zola, Baron Strucker. The "foot soldier" level of HYDRA guys aren't WWII guys, per se.

The "soldier" keyword can give you other ideas for WWII figures as well. (Wolverine and Black Widow teamed up with Captain America back in WWII in one episode....)
