X23 (Patreon)

Having no natural expiration date has its benefits. For instance, X23 managed to live long enough for technology to advance to the point of being able to further augment her mutant body and prevent any negative side effects from having adamantium grafted to her entire skeleton. One of her augments altered her body to have no upper limit of muscle size. With her very active lifestyle, near instant healing factor, and having a seemingly endless lifespan, X23 has used this modification of herself to build the physique you see before you.

It's my birthday today. This piece seems like a decent present. ;P
