Ivan (イワン Iwan?) is the strong man of the Bio-Hybrid trio consisting of himself, Kouki and Nanami. Ivan seems to have difficulty with holding his inner thoughs, and tends to blurt out what he's thinking without realizing it. After meeting her for the first time, he developed a sort of attraction towards Yoshino Fujieda (calling her his "honey bun" at one point). After gaining his ability to assume his final form, this prompted him to engage Rosemon in a duel for Yoshino's love, only for him to be defeated at their hands. In the same episode this battle occured in, it was revealed that Ivan is something of a mercenary, and underwent his transformation into a Bio-Hybrid for the sake of money. It was learned that he also had many brothers and sisters in Russia, and that he was fighting for their sakes. In the last episode, Ivan was also rising his D.N.A. into the sky, together with his siblings. 

Masaru, a second year Junior High student and undefeated street-fighter, is about to learn the meaning of the word "teamwork." After Agumon escapes DATS, an organization that deals with Digimon, it winds up in a fight with Masaru. Soon Yoshino and Lalamon come to capture Agumon, and the two fighters escape. After an evil Digimon appears, it's up to Masaru and Agumon to defeat it with their DNA Charge.<br><br>
Soon, Masaru must join DATS to put an end to the Digimon coming to Earth. With the help of Yoshino, Ikuto, and Touma, the group must stop any evil Digimon that appear, and return them to the Digital World.<br><br>
But not everything goes as planned...
