Abner is a character from All Hail King Julien. He is a rebellious, dim-witted hillbilly lemur who, along with his wife, Becca, repeatedly tries to overthrow King Julien.
Originally a mild mannered lemur with a dirty water hole problem, he is now an avid fighter for lemur freedom, thanks to Banana Guy Mike, who was really King Julien in a disguise.
Upon the "death" of Banana Guy Mike, Abner and his wife Becca take over LALA and swear to avenge their fallen leader by overthrowing the king.
Since then, LALA's attempts at killing King Julien have all ended with Clover beating them up.
Though it seems that Becca and Abner are the only members of LALA, they have repeatedly used Mort to carry out their plans.
