Kai was introduced as a good-natured, nice, teenage assistant to Ron. He, unlike Ron, understood the duties of being a mall cop as well as the restraints of the position. Despite thinking that Ron was somewhat nutty, he went along with Ron's commands up until Ron quit the force after a particularly heinous prank from Jude and Jonesy. After Ron quit, he became the only working officer and was noticeably less rough than his predecessor on teenagers. Not only this, but he was lazier, often ignoring possible emergencies in favor of goofing off and hitting on Caitlin. (Admittedly, he didn't encounter any emergencies up until the end, and that one was engineered.)
Kai first saw Caitlin on a security monitor when Ron was introducing him to the gang, whom he deemed their enemies. Caitlin, codenamed Cupcake by Ron, instantly drew his attention. When he met her at the Big Squeeze, he flirted with her until Ron commanded his attention again. After Ron quit and he was made the main security officer, he spent most of his time hanging out with her. Eventually, this hurt him, as for part of the final scheme Caitlin had to steal his security keyring.
After he was fired by Ron, Kai took a job at Frilly and Pink. Caitlin noted that the outfit was a major turn-off, and he only appeared once after this episode (and never again with Caitlin), suggesting that Kai refused to quit his job and a breakup occurred between him and Caitlin. Kai is voiced by Drew Nelson, who is also known as the voice of Duncan on the various "Total Drama" series.
Oddly enough, he made a cameo in "Dirty Work", once again as a security officer. He was accosted by Jonesy, who fired him in Ron's place and under Ron's orders. It was never explained how he got rehired or why he came back to the security force.
