His only known appearance is in Planet Blupi. He's the one who started the war between the Blupis and him when his rocket crash-landed on their planet.
He may not look harmful to Blupis, but he can create enemies via the buildings he built in his area. But apparently, he can run over traps like dynamites and sticky traps, his only weaknesses, much like bulldozers.
In the last mission, he got so furious that he refuses to move out from his place back to his rocket unless the path is complete.
