Garth (Atlantean: Γαρθ, Tempest, born Elaphebolion 28th, 152,509 / April 13th, 1994) is Aqualad's best friend from Atlantis. He is currently studying Atlantean sorcery at the Conservatory of Sorcery under Queen Mera, and was in a romantic relationship with Tula before her death.
Garth resembles a Caucasian teenager, with black hair, purple eyes and a slender build. His hair is relatively long, but a portion of it is caught up in a ponytail at the point of his back of the head, and the rest comes down to the nape of his neck and jawline. He wears a skin-tight swimsuit that exposes his arms and legs. It is predominantly blue-gray, although on the torso it has a midnight blue vest-shaped design, with azure lines tracing its edges and collar area. Around his waist, he dons a matching belt with attached tassets hanging down over his upper thighs. He also wears midnight blue bands around his forelimbs.
