Seeking to be of help to other teens in trouble, Garth became one of the founding members of the Teen Titans. Still shunned by many Poseidonians despite his heroics on their behalf, Aqualad was sent away to be schooled in Scotland, at a school on the shores of Loch Ness, as seen in the "Teen Titans" series. Soon, life for Garth became increasingly difficult, both at home and away. Mera was kidnapped, forcing the Aqua-duo to go in search of her, during which time Garth's left arm was nearly severed by an attacker. While he mended in the hospital, a plot against the Crown developed and Aqualad was forced to escape, finding that he was being deliberately over-medicated to keep him from thwarting the usurpers.
