Oculama

Somewhere, in a different galaxy, an eternal battle rages, between the Blue Planet and the Yellow Planet. Commander Ter Leyland, a fierce Blue soldier, piloted a Class 3 Exoplanetary Astromech. During a skirmish in orbit, the superheated slug of an enemy railgun struck Leyland's mech, causing an instant mechanical failure. The concussive blast of the slug shot Leyland into the yawning expanse of space, where he drifted for months. Right before his emergency life support systems finally blinked out, he was sucked into a wormhole. He awoke on a forgotten beach, his mech in pieces. He has only one goal - to return to the battlefield - by any means necessary.

His exoskeleton was meant to keep his muscles from atrophying in the vacuum of space. It pumps him full of enough nutrients and stims to allow him to constantly fight without ever needing rest. His current emaciated state is a result of the built-in automated system rationing smaller and smaller doses while he drifted aimlessly through space. Can't let a good soldier go quietly.

His anti-personnel service pistol has only one clip - its purpose was to be used on oneself, rather than the enemy, in order to evade capture.
