Titre original : The DATS Team Annihilated?! Clash, Mercurimon
After overcoming difficult hardships along their trek, the DATS finally arrive at Infinity Ice Ridge. To their surprise, the old man, Homer Yushima, is waiting for them near the entrance, leading them to a cave shortcut. Once inside, they make their way through a swarm of Tsumemon, and then against Keenan, who is bound to defeat the humans once and for all. However, Gotsumon betrays Keenan and takes the whole group hostage, except for Marcus, delivering them all before Merukimon. Saving Keenan from certain death, Marcus and Agumon hurry to Merukimon's palace for a final showdown.
