What's the best combination of mutants needed to beat the video game X-MEN Legends 2?

Types of mutants include: energy wielders, psionic manipulators, & physical powerhouses. Some mutants have a combination of the three or their power can affect the overall effectiveness of other allies.

A few mutants also use hand-held weapons such as swords or guns. A few characters automatically heal or have the ability to heal allies.

If you can't answer the question, then what's your favorite combo to use?
