Eventually, Doctor Khan was able to examine Lothar when he had some form of breakdown, and found some unusual devices and anomalies inside him. We discovered that he was the result of a (presumably failed) secret Starfleet experiment (codename GWIII – Great Warrior, project prototype III). When that project was cancelled and disavowed, Lothar was exiled to the Murgatroid … Starfleet's "dumping ground". Lothar awoke, stole Surak's Razor, and crashed into the Starfleet Command headquarters building on Earth. We later learned that he had been summoned by Admiral Janeway, who planned to upgrade and duplicate his systems, as well as place him completely under her control. She failed in that last task, as he broke free before she could activate his restraining program. Eventually, I was also captured and tortured by Janeway. After I discovered that she was actually an imposter from a "mirror universe", Lothar and I escaped.
Janeway's upgrades to Lothar's implants made him even more powerful. He was able to walk through walls by grasping and disintegrating them in front of him (he called it "hugging the walls", and appeared to accomplish it by dispersing the molecules with an unfocused short-range transporter field lacking a heisenberg compensator). During our escape, he also "hugged" a couple of starships to get us out of the Sol system. His upgraded internal gravity generators had further enhanced his strength, and were also what he used to make short "jumps" in space (as long as he was within close range of a ship or asteroid upon which to focus his gravity field). The upgrades also restored some mental stability and memories which he had previously lacked.
However, while we were in hiding (before we regrouped with the Murgatroid to overcome the
