Pangolins are cool. Cyborgs are cool. So pangolin cyborg for sona it is.
Both his hands can be retracted and a pop-out gun can be deployed in their places. Both XM4s contain a red dot sight and 3D print rounds when not in use to provide a transfinite amount of ammunition. Because of its versatility, stopping power, and the fact that FN Herstal weapons are cool, the 5.7x28mm round seen in the Five-Seven and P90 was selected for the XM4's caliber.
His ball form has sharp edges in the middle as well. Also, his head, torso (save for some of the chest) and upper arms are still fleshy, so those can be considered his weak spots. His forge is usually holstered to his side like a grenade, and can reform itself into its forge shape for use, as well as a jetpack mode
Maybe someday I'll give him a more in-depth backstory. Maybe even a series. iunno
Character belongs to me
