Digimon Adventure (PSP, English Sub): Part 108: Crossover Dungeon 6/8 (Xros Their Hearts)

Tai, Agumon, and a wounded Hackmon continue through the Digital Dungeon after parting from Marcus and his Agumon. They are ambushed by a horde of Chrysalimon, but are rescued by Shoutmon and his human partner, Taiki (Mikey) Judo, leader of the Xros Heart team. Shoutmon defeats the Chrysalimon, and the group must escape before more attackers arrive. In Area 2, Tai explains the situation to Mikey and Shoutmon, and the trio become honorary members of Xros Heart. In Area 3, they confront a fake OmniShoutmon that lacks the DEF Charge Omega ability but still possesses Ultra Counter. The fake is defeated, allowing Tai and Agumon to split from the group while Shoutmon continues with the unconscious Hackmon, all while Mikey keeps the team focused on their shared goal.
