Digimon: Digital Monsters - Season 1 Episode 13

T.K. is attacked in Primary Village by Leomon and Ogremon, until Tai, Matt, Izzy, Mimi, and their Digimon arrive to his rescue, where they use their Digivices to free Leomon from the Black Gears. Leomon later explains the prophecy that the children, as "DigiDestined", are to the saviors of the Digital World. The group fights Devimon, who absorbs Black Gears and Ogremon. Devimon defeats the DigiDestined, even when Joe and Sora rejoin them. Patamon Digivolves into Angemon when T.K. is in danger and sacrifices himself to defeat Devimon. Angemon's data reconstitutes into a DigiEgg, and File Island begins to reform itself. The DigiDestined are then suddenly contacted by Gennai.
