[@FalloutJack] Fusion-powered/heliokinetic cyborg is the base idea. More in-depth, the guy is a bounty hunter who has something of a hero-worship complex going on with Samus Aran. So he’s been modifying himself with tech he’s pinched here and there (he may have stolen some things from the Federation, which they might be using against him to get him to work for them, just a thought) in order to be just as capable a hunter as she is.
