Kyuubey the Failure is a character from the All Worlds Alliance series of fanfics.
Kyuubey the Failure is ousted incubator whom seeks to save magical girls from certain doom.
After the events from Mitakihara, Failure decided to retire as an Incubator and live his days as a house pet for Oriko Mikuni at the Uzumaki Villa.
Kyubey is a small cat-like creature, about two feet long (including tail). His entire body is covered in often clean white fur. He has what appear to be four ears; two that resemble an average cat, pointed and up, while the other two appear as long tassel-like appendages that split into three sections at their tip. The tassels fade from white to pink and have three red dots horizontally before the splits. they also bear a pair of floating golden rings. Kyubeys face is his most well-known feature; two large blue eyes with a thick eyebrows and a tiny, sigma-shaped "cat mouth". His tail has burnt end.
Unlike most Incubators, Failure has emotions. Failure was born different, he was the only Incubator that is capable to show emotions, and he was the only one who realized how horrible this system is and rebelled against. The other Incubators called him a failure and would try to get rid of him, in fear that he would ruin the system. He has been hiding for quite some time because as he was afraid of death.
Failure still had the capabilities to perform a contract and grant wishes. But he decided long time ago, that if he was going to do one, he is only doing it once. Failure can turn a normal girl into a magical girl without altering anything, such as placing their soul inside gems.
- Despite expressing that he'll only do a contract once, Failure formed a contract on both Madoka Kaname and Hitomi Shizuki.
