Mercury

Derek is the Australian  DigiDestined  encounter by  Cody  and  Joe, who is partnered with a  Crabmon. While on the beach, Cody and Joe saw Derek, who was wind surfing, come under attack from an  Ebidramon, a  Gesomon  and a  Shellmon. He escaped them, but they were then all attacked by a  Scorpiomon, who was seen off when  Submarimon  and  Zudomon  teamed up with  Coelamon , Crabmon's  Digivolved  form. Derek then reappeared when  MaloMyotismon  was infecting Earth and the  DigiWorld  with darkness, to join the other DigiDestined of the world in uniting against the villain. Derek appears in "Digimon World Tour, Pt. 2" and "A Million Points of Light." His voice is supplied, fittingly enough, by Derek Stephen Prince.
