Neo Saiba

Neo Saiba is an evil Tamer in V-Tamer and the brother of Rei. His original Digimon was a Greymon that he rejected after it kept losing in battle. When he worked for Daemon, he had a lot of Digimon at his disposal, including a Devimon and an Ogremon that could DNA Digivolve into SkullSatamon, which he used to kill Etemonkey, MetalGreymon (which was digivolved from his own Greymon), Ghoulmon, and more. Each of them was killed by either Neo or Zeromaru. Then he received Arkadimon from Daemon, which he used to kill Piedmon and later Rosemon. He later brought it during the invasion upon Lord HolyAngemon's castle with an army of Airdramon, Devidramon, Vilemon, Devimon, a Boltmon, a Gryphonmon, a Megadramon, a Gigadramon, and a VenomMyotismon. His Arkadimon defeated Leo and Lord HolyAngemon. Sometime after the invasion and after Rei threatens to stop the fight by jumping off the cliff, Neo and Taichi stop their rivalry. After the event, Neo befriends Tai and the Alias III again and saves Taichi's life. He goes on to win the next D-1 tournament and keeps his friendship with the four in the Real World.
