- "Galaxy Blue!"
- ―Blue Galaxy Ranger's Roll Call[src]
He is also referred to as Blue Galaxy Ranger or Lost Galaxy Blue Ranger - variations on his in-show label, though the latter is more in reference to the show than a proper label.
Straight-laced, sensible and ambitious, Kai is the classic overachiever. Having been brought up in a strict military family, he always does things by the book and likes everything in its place. His orderly world is turned upside down when he becomes a Power Ranger, and he must learn that sometimes rules are meant to be broken when it comes to saving the universe. He is apparently a good friend of Kendrix Morgan. His fighting style consists of grappling moves and throws, presumably taught by the military.
Kai was responsible for the majority of the meals the Rangers ate aboard Terra Venture. When a lovesick Kai rendered himself bed-ridden for several days after a romantic letdown, the other Rangers complained about the lack of decent food to eat, as Kai was the Galaxy Ranger who either had the greatest cooking expertise or the only one who was willing to cook for the group.
In Lightspeed Rescue, Kai returned to Earth with the Galaxy Rangers and helped the Lightspeed Rangers defeat Trakeena for the final time. He fought alongside Chad Lee, the Blue Lightspeed Ranger and his Blue Ranger successor. He returns to Mirinoi.
Legacy of Power
Kai and the other Galaxy Rangers returned as part of the army of Legendary Rangers that helped the Mega Rangers defeat the Armada once and for all, fighting in a huge battle against hundreds of X Borgs and dozens of Bruisers. Once again, he returns to Mirinoi.

- Kai became the first Power Ranger to share a first name with a Sentai character with the introduction of Kai Samezu/GaoBlue (fittingly, another water-based Blue Ranger) in Hyakujuu Sentai Gaoranger. Both also share their name with Kai Ozu/MagiRed of Mahou Sentai Magiranger.
