Resurrected by Great Satan for the series finale as the main pilot of Dora Talos. In life, he would not let his mother hug him whenever she wanted to. He later dies in his mother's arms following Dora Talos' final destruction at the hands of Ultimate Daizyujin.
- Originally, Kai's counterpart, who was reportedly going to be named Bubba, would have appeared in the Doomsday, as it was planned to be the season finale.
