A mysterious new villain called Trident appears and starts stealing nuclear waste from ships. While on a mission to stop Trident, The Titans meet Aqualad, an aquatic hero who knows more about Trident’s plot, and his sidekick Tramm, who helps rebuild the T-Ship while the Titans search for Trident. While Starfire and Raven fawn over Aqualad, Beast Boy and Aqualad quarrel over who is better. They eventually realize that Trident is more than one person and soon discover a colony of Tridents. Playing on Trident’s ego, Beast Boy gets all the Tridents to quarrel with each other. The Titans then lock the remaining clones in a cave, and Aqualad and Beast Boy put aside their differences.
