Alias III

Alias III are a group of Tamers chosen by Neo Saiba to stop Taichi Yagami. They each fight a one-on-one fight against Taichi, each hoping to defeat the "bug." Eventually, however, they find out that they were just a way to stall for time so that could have the power needed to defeat him. They are also used as a means for Arkadimon to get more food.

Hideto Fujimoto
Hideto Fujimoto is a member of the Alias III and has two Digimon partners instead of one. They are Warg the WarGreymon and Melga the MetalGarurumon who can DNA Digivolve into Omnimon. Hideto is the third and final member of the Alias III to fight Taichi Yagami and Zeromaru for Neo Saiba after the rest of the Alias III failed. He blames himself for what happened to Rei Saiba (Neo also blames himself, too). He is relentless to destroy Taichi and Zero, going as far as pushing his two digimon several times past their limits, and it was that battle where he is shown the true meaning of friendship. He later helps out in the final battle against Arkadimon where Omnimon would have been killed if Hideto didn't have him De-DNA Digivolve. He keeps his friendship with the others in the Real World and his partner was the only digimon of the Alias III to not be deleted.

His contribution after he reforms played a big part in defeating Neo. Since he was the only one who had a digimon after the battle, it was his experience that he passed onto Taichi that helped Zero survive the first encounters against Arkadimon. He also used Omnimon to help the ones fighting Neo fly when Zero was badly injured. He, along with Leo and Lord HolyAngemon, stalled for time while Zero recovered. He was also able to help convince Neo that what he was doing was wrong. He is also an accomplished Tamer in the real world, only being defeated by Neo at his school and only behind Taichi and Neo in terms of power. He is also shown to have similar feelings to digimon as Taichi, not wanting to delete Warg and Melga when Neo told him they were too weak. His kindness to them paid off as it was this kindness that let them evolve.

Omnimon
Omnimon is partnered to Hideto of the Alias III. Omnimon is made up of Warg the WarGreymon and Melga the MetalGarurumon. During the battle, Omnimon realized that Zeromaru was a good guy and lost the battle on purpose. This caused Hideto to switch sides. Later on, Omnimon fought Arkadimon when Neo dismissed the Alias III but was critically wounded and barely managed to flee with Hideto. Later he helped defend Lord HolyAngemon's Castle from an attack by Neo, where he again fought Arkadimon until Zero took over. In the end, he is the only digimon of the Alias III who was not destroyed.

Before the events of the series, Hideto used Warg and Melga to secure the spot of best Tamer at his school, only to be dethroned when Neo arrived. Though Neo suggested he delete them for being weak Hideto refused, saying they were his friends. This kindness was what lead them to one night jogress into Omnimon, and it was this evolution that was partially responsible for Rei's accident. Their friendship is shown again when both Warg and Melga refused to continue fighting against Zero, knowing well that Hideto is fighting for the wrong reasons.
