Digimon Fusion
Agumon appears in the first ever Digimon Manga "C'mon Digimon" with a different design than what was used in other media, having been redesigned by Tenya Yabuno. This design was never used again. Agumon also appears in "Digimon Next" as the partner of Tsurugi Tatsuno. It initially appears in its 1997 design, only to mutate into its 2006 design during the course of the story, which causes it to go down the same digivolution line as Marcus Damon's Agumon - only with as its Mega form. Tai's Agumon's appears during a cross-over in the "Digimon Fusion" manga and "Digimon Adventure V-Tamer 01", with Tai's Agumon meeting his alternate universe counterparts. Finally, various Agumon cameo in the rest of Digimon's Mangas.
