NeoCrimson is an experimental lifeform that is a fusion of the human Tamer Crimson and the Chaos series Digimon. It inherits its feet and cannons from Chaos Lord, ChaosMetalSeadramon's tail, and the two red floating ribbons on its back from ChaosPiedmon. It wields ChaosBlackWarGreymon's "Dramon Destroyer" on its right arm and has its legs as well as its "Brave Shield" on its back. Its shoulders, body, left arm, and head are a fusion of ChaosBlackWarGreymon and Chaos Lord.
