Alliin Mepou was a Human male Meatlump thug who lived on Corellia during the Galactic Civil War. By the time of the Battle of Yavin, Mepou was an old man and a very disillusioned Meatlump. In 1 ABY, the old Meatlump was smashing some generators in Coronet to please his lieutenant, Kaiya Merel, when he encountered a spacer. The spacer was working for Vani Korr, a Corellia Times reporter who was investigating the Meatlumps. Mepou confessed he could not retire from being a Meatlump unless a new person take his place. The spacer, who wanted to infiltrate the Meatlumps, accepted to replace Alliin and the old man finally retired. The spacer moved to work for Kaiya Merel while Alliin Mepou planned to go find some seashells on the beach, or jut sleep all day and watch holovids.
Alliin Mepou appeared as a non-player character in the 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game developed by Sony Online Entertainment and published by LucasArts, prior to its closure on December 15, 2011. Alliin Mepou was added to the game with the update dubbed "Chapter 10: The Search for the Meatlump King," released on June 19, 2008.
