This papercraft is WarGrowlmon, Guilmon's ultimate form, an Android Digimon whose Japanese name and design are derived from "Great Growlmon", and whose English name is derived from "War Growlmon", based on the anime, manga and video games series Digimon, the paper model created by Destro2k.
As its name suggests, it body has grown gigantic, and its upper body has been metallized with the strongest metal, "Chrome Digizoid". It is able to take flight with the two vernier attached to both of its shoulders, so it is possible for it to perform both anti-air and anti-ground attacks. In order to suppress its rampaging due to excess power, a restraining tool similar to a bit is attached to its jaw section. Also, since the "Assault Balancer" extending like a cable from its back section is extensible, it can be used to impale the opponent. It has the "Pendulum Blades" equipped to both of its arms.
The first few times Growlmon Digivolved into WarGrowlmon, he and Takato were linked mentally. Takato declared the "Atomic Blaster" attack at the same time his Digimon was about to use the attack. Takato even made some of the same movements that WarGrowlmon did.
