Fan Casting Green Lantern in Batman Beyond Animated Movie Series

A Tibetan boy and the Green Lantern of Space Sector 2814. Despite his young age, Kai-Ro showed remarkable maturity and wisdom. He had also been around the universe and exhibited excellent proficiency with the Power Ring. It is unknown how Kai-Ro received his ring, though the possible scenarios are that the ring chose him after the death or retirement of John Stewart, or Kyle Rayner, both of whom shared the duty of Earth's sector of space. He was more serene than most of the Justice League. When Superman brought Batman to join the group, Kai-Ro tried to temper down his hotheaded teammates, Big Barda and Warhawk. Also, while others immediately resorted to violence, Kai-Ro advocated for more peaceful resolutions. During a rescue mission, Kai-Ro, alongside other members of the JLU, used their powers to save civilians and stop exploding buildings from crashing down. When Warhawk was seemingly killed in an explosion, Kai-Ro was shocked, alongside the rest of his team. Afterwards, when Batman called Big Barda "pigheaded" after refusing to believe that Superman was the traitor when showing her proof, she reacted in anger. Kai-Ro restrained Barda while telling her to calm down. At that moment, Warhawk returned alive, much to their surprise and relief. The League confronted their leader, and Superman engaged his teammates, but Kai-Ro was able to quickly create a wall with his ring, which deflected Superman's heat vision. After Superman fled, they set off after him to the Fortress of Solitude, where they were able to subdue him. However, the League was suddenly attacked and subdued by Starro's psychic-parasite clones. After being released from the starfish's mind control by Batman and Superman, Kai-Ro, alongside the rest of the team, gained newfound respect for Batman. Kai-Ro continued to serve the Justice League Unlimited into adulthood.
