Deltamon

Deltamon is a Composition Digimon in the Digimon franchise, formed by the fusion of three separate Digimon. According to lore, its creation resulted from a computer malfunction caused by an electromagnetic storm, forcing the three independent Digimon to merge. Deltamon possesses three heads and two tails, specializing in tripartite attacks that utilize its unique body structure, enabling it to battle three Digimon as if it were one entity. However, due to the fiendish nature of the Digimon it's comprised of, they are only united in their destructive tendencies and often clash with each other, lacking a cooperative spirit. Deltamon resembles a blue, bipedal dinosaur with blue scales on its back, white skin on its belly and nose, and four toes with a black claw on each foot. Two reptilian heads adorn its arms – a metal-plated mechanical head and a dinosaur skull, both equipped with sharp teeth. It also features a "Δ"-shaped mark on its abdomen. Deltamon appears in Digimon anime, manga, games, and card games, often as an antagonist or an evolvable Digimon.
