Garth is a fictional character from DC Comics, originally known as Aqualad since his first appearance in 1960, but later went by the alias Tempest. As Aqualad, he was the teen sidekick and protégé to his guardian, the super-hero known as Aquaman, bearing the same superpowers as his mentor that allowed him to breathe underwater and communicate with marine life. He also possessed superhuman strength and speed that allowed him to move through the ocean with ease while withstanding the high-pressure depths of the ocean. As Tempest, he lost the marine communication power, but gained mystic-based abilities that allowed him to control the temperature of water and moisture around him, as well as the ability to emit destructive force beams from his eyes. As the adoptive Prince of Atlantis, he had, at times, been forced to assume his mentor's responsibilities as ruler of the oceans during Aquaman's absences, and has, in recent years, acted as Atlantis' official ambassador to the surface world.
