Ships are getting attack by an unknown villain that's stealing nuclear waste. The Titans go to investigate and meet a new hero, Aqualad, who teams up to help them. Unfortunately, Beast Boy and Aqualad start a rivalry with each other.
Plot[]
The Titans meet Aqualad.
The Teen Titans hear rumors of a criminal named Trident who sinks toxic waste ships on a regular basis. With this information, they head out on their T-Ship to the place where a ship had recently sank. The Titans get attacked from all directions by Trident, who seems to be able to be in many places at once. The T-ship gets damaged in the process. An underwater superhero, Aqualad, saves them and volunteers to look for Trident, much to the annoyance of Beast Boy. Aqualad explains that he and Trident are both from the secret city of Atlantis and Trident is its most notorious criminal. He claims to be perfect in every way, shape, and form, and has recently gained the strange ability to somehow be everywhere at once. Raven and Starfire develop crushes on Aqualad while Tramm, a friend of Aqualad's, helps fix the T-Ship.
Starfire and Raven fawning over Aqualad
Beast Boy and Aqualad separate in a cave and they get attacked by Trident, each of them defeating Trident. However when they reunite both of them claim to have fought Trident even though they were in different places. Beast Boy then suggests that there could be more than one Trident, making Aqualad scoff at the possibility of that happening. Beast Boy's hypothesis is proven absolutely correct when they look up to the ceiling of the cave and see what Trident has been using the toxic waste for - a massive cocoon colony containing thousands of perfect Trident clones that has already bread enough clones for an army. Beast Boy and Aqualad are completely surrounded, but before they are overwhelmed, Beast Boy defeats them by weaponizing Trident's most dominant trait: his ego. He challenges them to decide "which one of you is the best", since "there can't be more than one perfection". Because Trident is arrogant and thinks he is the best, so do his clones. The clones start fighting amongst each other trying to decide that, namely by trying to deduce who is the original to no avail, until they are all completely incapacitated. After that, Aqualad and Beast Boy are unable to stop the clones from hatching in time and they have no choice but to bolt for the exit. The newly hatched Tridents attack them en masse until they escape back into the sea, where the rest of the Titans show up, their ship repaired by Tramm. The ship collapses the mouth of the cave with its seismic blasters and the Trident army is sealed off from the rest of the world, neutralizing their threat once and for all.
With the Tridents sealed off in the cave, Aqualad and the Titans return to Titans Tower where Robin presents Aqualad a Titans Communicator and making him an Honorary Titan. Aqualad returns to the sea, not before having a race with Beast Boy.
In the shot where Beast Boy was seen annoyed by Raven asking Cyborg to "accidentally" leave his microphone switched off, the background with its blue walls and panel lights looks like he is still at base rather than at the bottom of the ocean.
Beast Boy's anglerfish form has a glowing lure, in reality, only female anglerfish have glowing lures.
Starfire's red hair. And ear...?
In the end, one of Starfire's ears is red as she and Raven fawn over Aqualad.
