While soaring through the network during "Holy Digimon", Izumi Koshiro and Tentomon got eaten by Whamon. Whamon was then attacked by a group of Tylomon controlled by Soundbirdmon, which caused Whamon to spit them out. The Tylomon then pursued Koshiro and Tentomon rather than Whamon, which Koshiro took as a chance to separate them and allow Whamon to run.
Before the events of "Bolt, Herakle Kabuterimon", Whamon was captured by Nanomon, who threatened to have it eaten by its Gran Kuwagamon should Koshiro not solve his riddles. The last riddle was a hint of where Nanomon was hidden: inside Whamon itself, and Koshiro was able to lure him out once he understood that by sending him footage of Whamon being set on fire by the newly-evolved Herakle Kabuterimon. Whamon was then released after Herakle Kabuterimon defeated Nanomon and Gran Kuwagamon.
After Negamon was finally defeated in "The End of the Adventure", Whamon kept swimming alongside Marin Angemon's city, propelled by Daipenmon's Kakikaki-kun and Kochikochi-kun, now accompanied by Digimon from the city itself: a Seahomon, a Sangomon and a Shakomon, as well as groups of Betamon and Seadramon, and a Ranamon. Meanwhile, El Doradimon floated above them.
Whamon is a Perfect level Ocean-type Variable Digimon that can be learned by the combination of any Baby Digimon or Agumon + Ver. 1 Digimon (Agumon, Betamon, Tyranomon, Airdramon, or Numemon). Its signature technique, Tidal Wave can recover the user or an ally Digimon's health by 25% of its DP. It costs 3 VP.
Whamon only appears as an enemy Spiral.
Whamon evolves from Aquilamon, Gaogamon, Geo Greymon, Numemon, or Sunflowmon. It can evolve to Bancho Leomon, Demon, Mirage Gaogamon, Ouryumon, Platinum Numemon, Rosemon, Seraphimon, or Shine Greymon.

The profiles were changed with mention of such catastrophes excluded, but were soon reverted back to normal. The others were Ancient Mermaimon, Caturamon, Minotaurmon Adult, Neptunemon and Tactimon.
