Digimon: The Movie
The ride leaves without Willis and Davis, who encounter Wendigomon which leads to a battle between him, Flamedramon and Gargomon. Before anyone is defeated, Wendigomon disappears, repeating his cryptic message, "go back."
Wendigomon reappears, as expected, but digivolves to Antylamon. He swiftly evades the attacks of Gargomon, Flamedramon, Halsemon and Digmon and throws all the Digimon around like rag dolls. Antylamon sinks into the lake (and changes the scenery), and rises again, but as Kerpymon. He then de-digivolves all the Digimon. However, they still try to fight, but to no avail, as Kerpymon grabs them and is about to eat them when Angemon and Angewomon cut off his arms and T.K. and Kari show up.
