This paper toy is a chibi Greece (human name: Heracles Karpusi), a supporting character in the manga / anime Hetalia: Axis Powers, the papercraft was created by smilerobinson. Greece is said to have a serious personality, but he often seems carefree and casual. He is often seen with cats, a reference to Greece's stray cat population. He loves naps and is often seen sleeping, but even though it seems there is nothing in his head, he has a love for philosophy and history, and thinks about all sorts of things. It is said that if you dig in his backyard, you'll find many ancient ruins and things belonging to his mother, Ancient Greece.
It is also implied that he frequently takes part in sexual activity; this is shown in a contribution Himaruya made to a Hetalia doujinshi anthology where England and France try to place the "blame" of the creation of the condom on him, seeing as he uses it very often. He replies by saying that while he does do these "activities" often, he doesn't really use condoms. [Source: wikia]
