BlackWarGreymon is the antagonist and now a protagonist in Digimon Adventure season 2. BlackWarGreymon showed up when Cody Hida's grandfather tried to talk Oikawa out of his plan. Myotismon momentarily took over Oikawa's body and with the additional power from absorbing one of the Dark Flowers, fired a blast of dark energy at Cody's grandfather. BlackWarGreymon stepped in front and took the full blast, saving Cody's grandfather's life, but he was mortally wounded by the blast. Oikawa fled and BlackWarGreymon realized that Myotismon was actually controlling Oikawa like a puppet. He used the last of his strength to seal the Highton View Terrace Gate to the Digital World to prevent Myotismon from entering the Digital World at that point. In the process, he found the purpose he had searched for all along and died a hero's death.
