After a tearful goodbye to Aquagirl, Tempest returned to Atlantis where he became the city's official ambassador to the UN. His relationship with Aquaman became more tumultuous, and Garth later learned that Aquaman had another son from a dalliance with an Inuit woman. This son, Koryak, grew to resent Tempest and the two became bitter rivals for some time. More friction arose between Tempest and Aquaman when Aquaman's lover, Dolphin, left him for Tempest (who had not been aware of the other relationship), but the two have since resolved their differences.
