Kibito Kai

Kibito Kai is the accidental Potara Fusion between Supreme Kai (Shin) and his attendant Kibito. After Old Kai demonstrated the power of the Potara Earrings by explaining Vegito's creation, Shin and Kibito experimented with the earrings and accidentally fused permanently. The resulting being combined Shin's divine authority with Kibito's supportive abilities.

In a moment of carelessness during the Buu Saga, Shin and Kibito each put on one of the remaining Potara Earrings, triggering an immediate and seemingly irreversible fusion. The resulting Kibito Kai was understandably confused, as neither Shin nor Kibito had intended to fuse. Old Kai, who had experienced his own accidental Potara Fusion with an old witch millennia earlier, was unsympathetic.

The fusion was eventually undone in Dragon Ball Super using the Namekian Dragon Balls. The wish separated Shin and Kibito back into their individual selves, revealing that the Potara Fusion was not truly permanent for non-Supreme Kai beings or could at least be reversed by a sufficiently powerful wish. The fusion had persisted through the remainder of Dragon Ball Z and into Super before this separation.

Kibito Kai had the combined power of Supreme Kai (Shin) and Kibito, though neither was an elite-tier fighter. In combat terms he was not particularly impressive by the standards of the threats that emerged after the Buu Saga. He was respectable but not competitive against the major threats of the saga.

Kibito Kai inherited Shin's role as Supreme Kai of Universe 7 and Kibito's Kai Kai teleportation technique, which proved useful for quickly moving between locations across the universe. The fusion also retained Shin's divine techniques and Kibito's healing abilities. He continued to wear the Potara Earrings that had created him.
