Wendigomon is a Champion Level Animal Digimon that resembles a brown monster with red eyes and a dog-like face. He has spikes on his shoulder, and carries a white skull on his head.
Digimon: The Movie
In the movie Wendigomon is known as Endigomon. After Omnimon defeated Diaboromon, everything seemed to finally be at peace. Until the virus that infected Diaboromon, infected Willis' Kokomon. For five years Willis had to watch Kokomon slowly digivolve into a monster. Kokomon, now in his Endigomon form, has been chasing Willis telling him to go back to he beginning, as well as making others who help Willis dissappear.
When Kari, TK, Patamon and Gatomon were in America to visit Mimi, they encounter Willis and Terriermon. They were being attacked by Kokomon. Terriermon fought his brother. After the battle ended, Kokomon disappeared. Aboard their train, TK and Kari encounter Kokomon again. He was about to make then disappear, until their D3 activated. This protected them and caused Kokomon to disappear, leaving the two stranded for the time being. When Davis, Willis, Terriermon and Veemon were separated by the others, they also encounter Kokomon. Terriermon digivoled into Gargomon and manage to defeat his brother.
When all the DigiDestined, (except for TK and Kari; they join the fight later on) are about to fight Kokomon, he Digvolved into Antylamon. He eventually Digivolved again, this time into Cherubimon. Veemon, and Terriermon golden armor Digivolved into Magnamon and Rapidmon and destroyed the virus that infected Kokomon. The once virus-infested monster disintegrated, as if at peace. Willis thought Kokomon was gone for good. What really happened is that Kokomon reverted into a Digi-Egg, because Digimon can never truly die. As Kari narrates one last time, the reformed Kokomon dances to "All Star" by Smash Mouth, and Willis finds him tone deaf.
His name and appearance are derived from the mythological Wendigo, especially its portrayal in the book, The Wendigo by author, Algernon Blackwood.
His name is sometimes spelled as "Cocomon".
Despite this, it actually sounds like "Kokomo".
He bears a physical resemblance to Mighty One-Eye from the The Thief & the Cobbler.
Kokomon did not make an appearance near the beginning of his respective film until the second half. This was most likely a way to surprise the audience that he is the main antagonist and not Diaboromon.
As Kokomon, he is voiced by Wendee Lee who also voices T.K. Takaishi in Digimon Adventure, Leafmon, Minomon and Mrs. Ichijouji in Digimon Adventure 02.
