Gambit / Remy LeBeau and X-23 / Laura Kinney are both of my favorite MARVEL characters.
I'm glad that I collected and keep the comic book series, watched the animated series (including the episodes that are involved), and played as them in MARVEL vs CAPCOM series (MvsC 2 & 3) with air combos.
Both of them are common for having a dark past and seeking redemption. Gambit has a connection with the Mutant Massacre of the Morlocks by Mr. Sinister (including his dark side as Death / Apocalypse's Horseman servant) and X-23 was harshly trained as a living weapon made by the Facility.
This is the best artwork that I ever saw.
