Derek

Derek, originally known as Dingo in the Japanese version, is an Australian DigiDestined who resides on Queensland's Gold Coast. He is partnered to a Crabmon.

Digimon Adventure 02
Derek makes his debut shortly after Cody Hida and Joe Kido and their partners destroy a Control Spire. He was out in the ocean on a surfboard with Crabmon, calling out for help and was being chased by a Gesomon, a Shellmon and an Ebidramon. When he makes it to shore, he introduces himself to Joe, Cody and Gennai's Australian counterpart, Hogan (Eucalyptus in the Japanese version). Joe and Cody assist in dealing with them by having Armadillomon, Ikkakumon and Crabmon threaten to cook them and turn them into "Digimon Seafood". The threats work and Gesomon, Shellmon and Ebidramon flee. Ikkakumon, Armadillomon and Crabmon chase them towards the Great Barrier Reef where another Control Spire was located. Joe, Cody, Derek and Hogan followed behind them on a small boat.

Once they see the Control Spire, they stop their pursuit of Gesomon, Shellmon and Ebidramon and focus on destroying the Control Spire. A Scorpiomon tries to stop them. Zudomon and Submarimon struggled to defeat the opposing Digimon; Derek had Crabmon Digivolve into Coelamon. The combined efforts of Zudomon, Submarimon and Coelamon defeat him. He then assisted in the destruction of the Control Spire. Afterwards, the Australian Chosen Children arrive with the Digimon they found.

Near the end of Digimon World Tour, Pt. 3 and making his second appearance, Derek is celebrating Christmas with Crabmon. He is eating pizza while Crabmon is given seafood ironically.

Derek makes his third and last appearance in the final episode in the fight against Malomyotismon. He is seen in Sydney raising his Digivice and after calling out Crabmon, his Digivice sends a beam of golden light which transports him to the Digital World. He stands with Joe and Yue Hong when he arrives in the Digital World.

Trivia

 * In the original Japanese version, Derek introduces himself to Joe and Cody in english and calls himself as a "Digidestiny" of Australia" instead of a Chosen Child. Probably as a reference to the English version's terminology
 * Derek and Crabmon are voiced by the same Japanese voice actresses who voice Tai and Agumon.
