In 2005, Toy Biz introduced the "Build-a-Figure" (referred to as a "BAF" in the collector community) to the Marvel Legends line. Each individual figure in the series was packaged with a piece of a larger figure. Mattel emulated this pattern in the DC Universe Classics line as "Collect and Connect" with five (and later six or seven) separate figures including pieces to build one of DC's bigger characters. Variant versions of figures include the same piece as the regular version. The goal is for the Collect and Connect figures to be around 25% larger than the basic figures. This is only a ballpark figure, though - the Collect and Connect figure's size will vary based on the character's needs, though significantly larger characters (such as Chemo (DCUC wave 9) or Anti-Monitor) will need to be reduced in size in order to be released in the line. Wave 1 and 16 featured the smallest Collect and Connects with (Rex Mason Elemental Man and Bane) which were only slightly Larger then the Standard Figures. In addition the Collect and connects were of Particular Molds many such as Kilowog, Validus (of Waves 11 and 14), and Arkillo (of the Green Lantern Classic Wave 1) all share a Basic Mold of in Arms, Legs, Torso Parts while other Appearences are different (Colors, Heads and Hands)
