Aqualad was the teenage sidekick of Aquaman during the '60s. He was also a member of the Teen Titans. He rode on a giant seahorse named Imp, and he had a pet walrus named Tusky.
Aqualad is a magical hydrodynamic teenager, from the Lost City of Atlantis. He is Aquaman's sidekick, ward, and trusted confidante. The two of them have a great number of jolly good aqua-adventures under the deep blue aqua-sea. Truly it is a life without regret. When Aquaman is too boring to hang out with (which he usually is... the man talks to fish), Aqualad spends his time with the Teen Titans.
Aqualad is the sidekick of Aquaman. Aqualad is also joined by Aquaman's other sidekick, Aquagirl.
