Vikemon

Vikemon is mega form of Gomamon. He appear in Digimon Adventure tri.

Determination
When attempting to rescue Meicoomon from the Digimon Emperor and his version of Imperialdramon, Gomamon quickly digivolves to Vikemon after Joe is shown that denying his burden as a DigiDestined means also denying Gomamon. Alongside Rosemon, he is able to turn the tide against Imperialdramon, even after he takes his Fighter Mode form, giving Leomon time to fight off his infection and save Meicoomon.
