Atha Prime was a character created by Kenner to be the big bad of the ongoing Star Wars action figure line after Return Of The Jedi. They had all sorts of plans for the line, but Lucasfilm turned them down. Years later Dark Horse comics used the character design as the Imperial Sentinel in the Dark Empire comic series. And then in 1998 when Hasbro was making figures based on comic characters, they made a figure of the Imperial Sentinel, finally making an Atha Prime action figure. Wookieepedia: Atha Prime, genetics master and ruler of the dark worlds, was an arbiter of the Clone Wars and a co-conspirator of Grand Moff Trachta's. He was exiled to the fringes of the galaxy by Palpatine, although the Emperor's death in 4 ABY allowed Prime to return to the galaxy and begin a campaign of conquest. With his Clone Warriors at his side and the double-decker Star Destroyer Annihilator at his command, Prime waged war with the Rebel Alliance, doing battle with its heroes, such as Luke Skywalker and Han Solo. #athaprime #kenner #kennerstarwars #starwarskenner #hasbro #hasbrostarwars #starwarshasbro #imperialsentinel #starwarsactionfigures #actionfigures #toys #toysofinstagram #rebelalliance #clonewars #lucasfilm #starwars #vintagestarwars #starwarslegends #ExpandedUniverse (at Portland, Oregon) https://www.instagram.com/p/CPFaRtphDXq/?utm_medium=tumblr
