This papercraft is Diablotiger, a Tiger-type Zoid, one of over 200 species of biomechanical life forms that provide the basis for TOMY's model kit, anime, and comic based Zoids franchise, the paper model was created by Ashley Ardis.
The Diablotiger is fairly enigmatic, having turned up from somewhere "far off in the future" along with its eternal rival Cyclops. It is described as having a cool personality, swearing loyalty only to one pilot it personally approves of as they seek out new, stronger partners and battle Cyclops.
While it sports many melee weapons, the Diablotiger's only ranged weapon is the Cyber Metal Cannon, which appears to fire energy projectiles. Defensively, it carries an energy shield, as well as chaff and optical camouflage. When that's not enough, it's also made of a mysterious "liquid metal" which allows it to self-heal. It's main form of attack, the Cyber Claws and Fangs, charge with the same energy from the Cyber Metal Cannon, and can appearently remain charged indefinately.
Oddly enough, the Diablotiger is identified with Guylos emblems on the box and Zenebas ones on its sticker sheet, leaving its alliance somewhat ambiguous other than "Imperial". [Source: wikia]
