Later on, when Tai and Agumon were in the bathroom, Ogremon and Leomon caught them by surprise. Leomon attempted to kill Tai, but was stopped by a Digivice, freeing him from Devimon's control. But somehow, Devimon brainwashed Leomon again.

When the DigiDestined got seperated, Leomon attacked Izzy, Mimi, Palmon, Tentomon, and Centarumon. Both Leomon and Centarumon fought each other but Leomon was scared off when The 2 DigiDestined used the Digivice.
