Dolphin was a professor at Palo Alto University.
Dolphin first appeared when Yamaki gathered the Monster Makers together. He later constructed the ark to take the tamers home, and observed the battle with the D-Reaper while trying to figure out how to destroy it and help the tamers any way he could.
He was also the one who cleared up all misconceptions about Digimon, telling the world that the tamers' Digimon were nothing like Vikaralamon.
