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, the paper model created by ProjectKITT. The scale of the paper craft is in 1:32.
Ratchet has a dry wit, often giving his wounded comrades a hard time for taking hits he somehow avoids. With the Energon supplies becoming less and less, he works to find new ways to make do, and he'd really prefer if the Autobots didn't risk injury to protect humans. He'd also prefer the humans weren't brought back to Autobot Outpost Omega One but since he is unfamiliar with human tech, he needs Raf Esquivel to help him out. However, for all his views on humans, deep down Ratchet admires what the tiny fleshies bring to the fight.
Ratchet is often frustrated by the primitive Earth technology available to him on Earth. Ratchet is also the creator of the Ground-Bridge Technology, which is used by the Autobots to travel between any two points on Earth and an alternative Low-Powered version of the Cybertronian Space Bridge. Originally contemptuous of the Autobots new human allies, he eventually gains some respect for them, especially Raf, who twice fixed the Autobot's "Earthian" Computer when Ratchet could not.
