TBA King Zaiger appeared in episode 25 and 26 of Mirror Fight. Stock footage of his fights in Mirrorman were reused in this series.
- King Zaiger is the first Mirrorman kaiju that showed any intelligence without a human form as when it last fought Mirrorman(who was blinded by the time), it took advantage and tried to fool Mirrorman on where it is.

- Green Slime: Can shoot out a green slime that can blind the opponent.
- Smoke Breath: Can shoot smoke out of it's mouth.
- Invulnerability: King Zaiger seems to be invulnerable to all Mirrorman's attacks. He however seems to lose this ability when he is harmed in some way.
