Jaxxon was a character that was created in the first couple of issues of the Star Wars comic series after Marvel was done with the official movie adaption. Jaxxon was a quick-witted creature known as a Lepi and was a smuggler from Coachelle Prime as his profession. He teamed up with Han Solo and Chewbacca on a few occasions. The character however looked very goofy and did not capture the imagination of the readers and was quickly left out of the story.
Years later, when Marvel re-acquired the rights to publish Star Wars, they made a goofy variant cover of issue 1 in which Jaxxon tries to get to the other Star Wars characters through a door, which the others manage to stop successfully by barricading the door. Jaxxon however knows the characters are there since he hears the loud breathing of Darth Vader.
