Usagi Yojimbo
Usagi Yojimbo is a samurai rabbit and master swordsman from an alternative universe's 16th century Edo Period in Japan, where animals are the dominant species, not humans. He appeared in two episodes of the 1987 series. Usagi Yojimbo is a comic book series created by Stan Sakai starring the ronin hero rabbit, Miyamoto Usagi, which had several crossovers with the TMNT comics; apparently the TV show writers did not understand the distinction and misnamed the character after the comic book.
The character returned for the 2003 animated series with his actual name, Miyamoto Usagi, and became a friend and close ally of the turtles, especially developing a strong friendship with Leonardo, since both are swordsmen. Leonardo also ended up in Usagi's dimension when Ultimate Draco scattered the five mutants to different parts of the multiverse.
