The last of the X-Force members

While it is easy to see and guess who most of the mutants in the X-Force concept art are, there is one about whom we are not so certain. Thus, the last of the members may be one of 4 characters: Rogue, Hope Summers, Tabitha Smith, or Feral.

But while she looks like the Rogue we all wanted to see, she cannot be her given the sleeveless gloves she wears. And while Hope Summers seems like a nice addition, given her ability to mimic the superpowers of other mutants, this would make her the second Omega level mutant in the team.

The best chances are for this mutant to be a more humanized version of Feral, given the visible hair on her arms, her eyes and her long nails/claws. Plus, the hoodie may just cover up her mutation (pointy ears). In the comics, she may be considered the female version of Sabretooth, having basically the same powers (increased agility, superhuman senses, strength, stamina, regenerative abilities, and so on – plus a prehensile tail).

The other option is that the last X-Force member is Tabitha Smith, a mutant who can generate orbs of pure plasma – in a way, she can manipulate energy. And since Cannonball is also an expert at that (since the forces which hit his energy field can be redirected), it doesn’t make sense to have another mutant just like him.
