Laura Kinney a.k.a. X-23. The 23rd attempt at cloning Wolverine is so big.  She's December and January's winner of Mutant of the Month. Her win comes from her part in the last X-Force arc entitled "Not Forgotten" in which X-23 got around quite a bit. Coming off of her battle with Apocalypse and Stryfe, X-23 was on mission to save her friends Surge, Hellion, and Boom Boom. After she had saved Boom Boom and killed The Leper Queen, exhaustion overcame her and she was captured by a new branch of The Facility. There she had her arm cut off by Kimura but that did not slow her down at all. She teamed with a rogue HAMMER agent and took down the complex single handedly....literally. She was found by Wolverine and Domino and taken back to Utopia where she regrew her arm and asked Dr.Nemesis to put her claws back in. It is clear why she is the winner this month after all that. Friendship, destruction, mayhem, and a little depression makes for a good X-Force tale.
