|Debut||Digimon World 4|
BlackWarGreymon X is a Dragon Man Digimon and carrier of the X-Antibody. Its negative power has been condensed to its maximum, and its cunning for seizing victory by any means necessary has been accelerated. It has imparted the strongest toughness of the "Brave Shield" to the "Dramon Killers", leading to it possessing perfected equipment of unified offense and defense. Due to its fighting style, in which it instantly plunges into the heart of the enemy with the vernier it has equipped to its back, which boast explosive acceleration at the expense of it being able to fly for extended periods, it has certainly become the strongest form of land combat Digimon, a "Land War Hero".
- Ankoku no Gaia Force (暗黑のガイアフォース? lit. "Dark Gaia Force"): Similar to WarGreymon's "Terra Force", except that it takes all of the "negative emotions" within this world and concentrates them into one spot, and then fires it.
- Hades Force: Continuously fires its Special Move "Ankoku no Gaia Force" at ultra-high speed. Evasion of its "Hades Force" seems impossible.
- Afterburst: Accelerates its attacks with its vernier applied to the "Dramon Killers". It is also a one-hit knockout technique.
- BlackWarGreymon (X-Antibody) (ブラックウォーグレイモン（X抗体）)
- BlackWarGreymon X (ブラックウォーグレイモンX)
Samudramon, designed by As'maria, was originally created as BlackWarGreymon X. He was asked to redesign BlackWarGreymon to have more Japanese flair, so he designed it to dual wield two swords. It was loved so much, it was renamed and made a standalone Digimon, instead of an X-Antibody counterpart.
