I'm just brainstorming ways to synergize super hero teams, starting with...

X-MEN

MOVEMENT
Cyclops - he could have a "cover fire" style ability a la Agent Skahen. Maybe limited to mutant figures.
Storm - She frequently carries her teammates by creating a gust of wind. Maybe she could have some type of D20 carry-- if she rolls 1-7, she can carry one medium or small figure, if 8-14, two figures, if 15-20, 3 figures.
Marvel Girl/Phoenix - she could have a version of Jotun's throw, but that can be activated from a distance and wouldn't cause damage to friendly figures.

DEFENSE
Colossus - He could have a ranged version of Tandros' power in which non-adjacent attackers must attack him instead of any friendly figures adjacent to him.
Kitty Pride - She could have a Smoke Powder type power for figures standing next to her, but it would work against melee attacks, too.

MULTIPLE ATTACKS
