GammaBigdramon is a Beast Dragon Digimon based on a Mechanical Megatherium. It can be considered a counterpart to the Greymon line, as it's digivolution line shares many similarities to each other. Unlike MetalGreymon, though, it may be a Vaccine Digimon like it as well, but is more destructive in nature. The earphones resemble the scarf of the ultimate warrior from another world, and due to the resemblence, many mistake him and BetaBigdramon for said warrior. It goes almost completely undetected in darker areas, as it's fur is made to reflect as little light as possible, making it blend in perfectly with darker areas, with even in well lit areas it's body appearing mostly dark.
