I knew Kuseno is a bad guy. Calling himself a scientist of justice was never not gonna be suspect.
Genos(ide)
Matches the two cyborgs from Neo Heroes.

Expanding a bit on that, I always wondered whether Genos and Kuseno were based on Osamu Tezukas
Dämons (warning, it's a pretty gruesome read); only ever a small portion of it was translated online sadly, but if you look at Haight and Dr. Becker, they are very similar to Genos and Kuseno.
For Genos and Haight - their names are both based on extremely negative concepts; Genocide and Hate.
Both have a tragic backstory that led to them losing large portions of their body, a deficit they made up for through cyborgification; both tend to carry their spare arms around in suitcases. Both are driven by revenge, not caring much whether they perish in its pursuit, and crucially, both don't really distrust their doctors.
The doctor in Dämons is an extremely sketchy character outwardly, in contrast to Kuseno; but Kusenos actions make him look about the same. Genos is essentially a teenage-aged test subject for experimental weaponry, the world at large seems to be unaware of Kusenos genius, despite him apparently having a stable source of funding for the million-dollar operation Genos obviously must be. And then there's the fact that he is apparently an arms developer...
