1530 years after his creation, he only appeared in 10 comic book issues
It's hard to think of a time when no one really knew who Rocket Raccoon was, but in the nearly 30 years after his creation, he only actually appeared in a total of ten comic books.
Although he first appeared in 1976 as a raccoon named "Rocky," it was nearly ten
years before he would appear again in The Incredible Hulk #271. He eventually got his own four-issue mini-series in 1985, followed by an appearance in Quasar #15 and in three issues of Sensational She-Hulk.
Rocket was actually only meant to serve as a one-off character, but Marvel writers and artists kept bringing him back for more stories. Now, he's an official member of the Marvel cinematic universe, both in the movies and the comics.
