Nichos

Nichos were cartoon characters that served as the avatars of non-controllable players (NPCs) in the browser game Chobots and were the main antagonists of Chobots. Nichos were an alien species that once co-existed with the Chobots, but they became archenemies over their disagreements on how to harness the power of a unique source of energy called Cho; while the Chobots sought to use cho for knowledge and creation, the Nichos used cho as a weapon for destruction. Since destroying their planet, the Nichos continued to oppose the Chobots in their floating cities.
