Erich had been the focus of many eyes across the galaxy. He was effectively an Emperor who was taking the front lines in a war this his soldiers were waging on his behalf. It was a rare sight, even in a place as large as the Milky Way Galaxy, which was itself full of thousands of interstellar civilizations, and the species which made them.
Yet Erich's experience as a special operations soldier came in handy. In situations where normal soldiers would perish. Erich expertly used his skills to not only survive, but eliminate those who attempted to kill him.
The race of insectoids that Erich was fighting were not like the Naraku, insofar as they did not rapidly evolve new breeds of bugs to fight whatever circumstances they came across. Instead, they were more humanoid, insofar as they were all bipedal creatures, albeit capable of flight.
