One very cool action figure we found was Usagi Yojimbo! Released by Playmates in 1990 as part of their extremely successful Teenage Mutant Ninja Turtles collection. This is a great figure!
Usagi appeared several times in Teenage Mutant Ninja Turtles (the comic, both of the animated series, and the toy line), and the Turtles have appeared in Usagi Yojimbo as well. In his guest appearances, he is closest to Leonardo, both sharing the same ideals and code of ethics.
