Part of the fun...
Of mutants, is seeing just what the mutant can do. It is frustrating when a mutant is depicted with no clear idea of the mutant's power.
Shinobi Shaw's version of the Hellfire Club had a full inner circle and yet it was never really stated or shown what each member could do.
Idie. Could someone tell me what her actual power is. I just remember she killed a group of people somehow and recently saw her weild fire and ice, I think.
Tessa was fun back in the day because she was simply described as a human computer before being relegated to an average telepath with cybernetic like information skills.
Maybe I am just missing one panel of explanation here and there, but are there any other characters who have undefined powers?
