One of the first mutants recruited by Professor Charles Xavier, Jean Grey has been an anchor of the X-Men since the team's inception. Tempering telepathy and telekinesis with warmth and compassion, Jean has overcome seemingly insurmountable challenges -- rising from the ashes of her apprent death like a Phoenix to stand in defense of a world on the brink of genetic war!
RECOMMENDATIONS
Jean is the second most powerful character (after Storm) in the game. Early on, she may not seem like much, but get her Psychic Shout up to Psychic Legend and you'll see what I mean. Her Telekinesis is useful when you don't have Storm to move objects or Iceman/Magma to build bridges. It's also a good attack move when you get it up to Legend level. Her Telekinetic Shield is a good defense, but unlike the AI, I didn't use it too much...everyone was dead before I remembered I had it. The few times I tried her Phoenix Force, it didn't seem like it did much, so I stopped using it. Build up her Psionic Strike until it's a maxed out Psionic Fury and her melee ability will rival that of Storm and Wolverine. You definitely need to get some points into her Mutant Mastery, as she uses energy quite a bit. Especially if being controlled by the AI. And Flight is always useful (although I relied more on Rogue or Storm for that). Focus is the main place you want to build. Add some to her Strike to help her out during melee attacks.
