U.S. retailer Target started selling Star Wars action figures exclusive 2-packs on October 1st, 2009. The 2-packs were themed based on the arena conflict seen in Attack Of The Clones. The series started with six 2-packs, including a total of 12 figures in 2009.
In 2010, Target continued the series with another six 2-packs (another 12 figures). Both series' contained re-releases and new Star Wars figures, and by the end of 2010 the entire series consisted of a total of 24 figures.
Each 2-pack came with a hero and a villain, except for the C-3PO and R2-D2 set. Although, it could be argued that 3PO counts as a villain since he came with a Battle Droid head.
The packaging was designed so that it created a half circle (Geonosian Arena) when put together with other sets.
