This transformers papercraft is a vehicle mode (HUMMER H2) Ratchet, an Autobot medical officer and tech support, who has a very dim view of humans who he considers to be a dull and primitive race, based on the Transformers: Dark of the Moon, the paper model created by Paper Replika. There is another Vehicle Mode Ratchet paper model at the site: Transformers: Prime – Ratchet Vehicle Mode Free Paper Model.
Ratchet, the Autobots' medic, is probably the bravest of them all. He'll risk his life to pull any wounded comrade from the battlefield. Indeed, he did not join Optimus Prime's team to be a soldier; rather, he's there to save lives, and thinks Prime is the best chance the universe has for peace.
A medic who dislikes violence, Ratchet's well-armed appearance is more due to being an improviser with surgical tools, such as his buzzsaw, which he discovered he had a penchant for due to his early experiences as a tool-and-die maker. When combat is unavoidable, he can employ these makeshift weapons with surprising agility for his size. His closest comrade is Arcee, and they share a common enemy in Lockdown.
