First Season (Digimon Adventure)
Gomamon first Digivolved to Ikkakumon to protect Joe from the Black-Gear-infected Unimon. Since then, Ikkakumon has fought various enemies like Devimon, Etemon and the henchmen of Myotismon.

But on August 3, Joe and T.K. tried to get back in Odaiba on Ikkakumon. However, they got ambushed by MegaSeadramon while they were passing Rainbow Bridge. Joe reliably saving T.K. from drowning gave Ikkakumon the ability to Digivolve to Zudomon, who defeated MegaSeadramon. Afterwards, in most battles, Ikkakumon would only appear briefly just before he would Digivolve to Zudomon.

Other than being used for battle, Ikkakumon was also used as a ferry for travelling across the water.

Second Season (Digimon Adventure 02)
One year after their adventure, Joe and Gomamon were reunited and Joe gave up his Crest power to free the Sovereigns. As a result, Gomamon lost the power to become Zudomon. Two years later, when the Digimon Emperor was conquering the Digital World, Gomamon was among the old generation Digimon to help the new gang out, appearing four times as Ikkakumon to fight Ebidramon, another MegaSeadramon, and BlackWarGreymon as well as Digivolve from Ikkakumon to Zudomon when fighting Scorpiomon and MarineDevimon.
