Geryuganshoop

Geryuganshoop was an alien general of the Dark Matter Thieves and the right-hand of their leader Boros, ultimately killed by Saitama during the invasion of Earth.

Fiercely loyal to Boros, Geryuganshoop was willing to throw itself into danger to protect him from intruders, while also recognizing its own rank well enough to issue orders to the rest of the Dark Matter Thieves from the ship's control room. Usually calculating, it could lose its composure quickly whenever the ship and its crew faced real danger. In battle it was notably arrogant, convinced no other psychic in the universe could match its telekinetic skill — a belief that led it to badly overestimate its own strength against an intruder who had already wiped out much of the crew alone.
