Between Digimon Adventure and Digimon Adventure 02Edit
The same time the original DigiDestined was fighting Myotismon. Digimon started to appear all round the world. When a Gorillamon appeared in New York, Michael received a Digivice and his partner Betamon. They both fought the Gorillamon and defeated him.
Digimon Adventure 02Edit
He debuted on Episode 14 "The Samurai of Sincerity". He and Mimi saw the gang in Digitamamon's restaurant and another Gorillamon appeared. Betamon and Palmon digivolved into Seadramon and Togemon to remove its Dark Spiral.
He appeared again on the world tour. He, Mimi, Davis and the American digidestined defeated Cherrymon. His last appearance was at the final battle with MaloMyotismon.
After the realities collapsed upon each other, he lost his partner and all memory of the events concerning ever having a partner. The SDCO later recruited him and Willis Price in an attempt to organize a tamer group in America. Though he does not have an official partner, he and Willis intend to rescue their intended partners and the other digimon in Book Seven so that they will not be destroyed in the chaos surrounding the murder of the Japanese Prime Minister and the accusations that Rika Nonaka committed the crime.
