Digimon Data Squad

Brought to DATS HQ by Yoshino, Marcus and Agumon learn that wild Digimon are placed in a teleporter to be sent back to the Digital World. With DATS still seeing Agumon as a threat, Marcus stops them from forcing Agumon into the teleporter and the two escape. Marcus resolves to hide Agumon at his house, only for the Digimon's existence to be found out by his mother Serah Damon and his younger sister Kristy Damon. From there, to Marcus's annoyance, his family and Agumon all quickly become friends. Marcus is further annoyed when he learns that Yoshino is going to keep an eye on him and Agumon indefinitely unless the youth becomes a member of DATS. The next day, Marcus passes by Kristy's school and learns that something is attacking the school's animals. Marcus plans a stakeout of the cages and places Agumon inside as bait, the culprit revealed to be a Kunemon that has been feeding off the emotions of Kristy's young classmate Takashi who secretly wished the animals would just disappear. No longer needing Takashi, Kunemon attacks with Yoshino's Digimon partner Lalamon digivolving to Sunflowmon to fight the wild Digimon. However, Kunemon digivolves to Flymon and uses his poison powder to paralyze Sunflowmon and Yoshino. By that time, have been unable to digivolve Agumon, Marcus learns how to access his DNA and activates it by punching Flymon before it is defeated by GeoGreymon. The old man who gave Marcus his Digivice then appears, telling the youth of the Digital World and all the opponents he could fight there. Returning to DATS HQ, Marcus is welcomed by Commander Sampson as a new member of DATS.
