From threeA Wiki
United Planet is a collaborative design effort between Mak Siu Fung, & Colan Ho. They have used the design concept/universe in sculpture, print media, and toy designs. In 2009 they collaborated with ThreeA to design two United Planet vinyl figures which were to be carried under the Showcase label.
It appears that ThreeA has dropped this project, due to unknown reasons. Different variations on these figures have been seen at Taipei Toy Festival (2011) without ThreeA's involvement.
