This papercraft is the Kon, based on the anime and manga franchise Bleach, the paper model is designed by Icthus7. Kon is an artificial soul modified by the Soul Society operation known as "Project: Spearhead" to inhabit a dead body and use his special powers to help the Shinigami fight Hollows. Kon's special power is in his leg muscles. His name is short for Kaizō Konpaku. Ichigo uses him to transform into his Shinigami form, leaving him in charge of his body the way normal Shinigami use artificial souls to look after their gigais. When not serving this purpose, Kon usually inhabits a lion plushy.
Kon primarily serves as a comedic foil in the series; when not inhabiting Ichigo's body, his normal plushy body is treated with little respect and much disdain, sometimes bordering on abuse.
Kon is quite perverted and is preoccupied by sex much of the time. He will often try to take advantage of his plushy body to get girls to hug him to their chests. Kon is especially attracted to girls with large breasts, which makes Orihime the center of many of his fantasies. In the manga he is also seen using Ichigo's body to gratify himself while fantasizing about Orihime and Rukia.
Kon's redeeming quality, which allows Ichigo and Rukia to see him as someone worth saving, is his views on the sanctity of life. Because he spent many years in the form of a pill, fearful that one day he would be discovered and disposed of, Kon has developed a moral stance that prevents him from killing anything. He will also risk his own life in order to save even the lowliest of creatures, and is angered to see people who belittle their creations and dispose of them off-hand.
