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
Cody Hida and Joe Kido first met Derek after assisting him in dealing with a Shellmon, Gesomon, and Ebidramon, which were pursuing him and Crabmon on his surfboard. With the assistance of the duo, Derek managed to terrify the Digimon trio into surrender, with falsified plans of cooking them.

Derek went with Cody, Joe and their Digimon to destroy a Control Spire out in the Great Barrier Reef, only to be attacked by a Scorpiomon. Zudomon and Submarimon struggled to defeat the opposing Digimon; Derek had Crabmon Digivolve into Coelamon, who successfully brought an end to its rampage. He then assisted in the destruction of the Control Spire.
