As G-Stealer, he was a terrible manbeast from the star system Mu Arae, just like Kita. It was originally thought, that this beast could replace genes of creatures it encounters, so that its name would have been Gene Replacer. This was an inside joke about Kiss's bassist, Gene Simmons and as a band greatly influenced by Kiss, Keinänen would in effect be Gene's replacer. It was, however, concluded that "replacer" sounded stupid and Gene couldn't really be replaced. In the end, the name was shortened to G-Stealer.
