Series 1

 New Figures (Using Generic Sculpts): The Atom, Dr Fate (w/ unique arms), Elongated Man, Amazo, Starman, Red Tornado

A collectible expansion on the original Justice League line, the JLU figures were either packed single with a simple accessory in a small card case. The first run of figures featured repaints of the original characters in modified uniforms and 'battle-damaged' versions of their original suits. The line then featured leading characters like Dr Fate and Atom. We see a revamped Green Lantern and Batman figures.

Singles

Each single figure had one accessory (not counting Green Arrow who has a bow and arrow and detachable quiver) and came with a collectible card. Some of the accessories are rather vital to each character (kryptonite, batarang, lasso etc). The line as singles didn't really give a 'generic' appearance as there were not many figures to count yet. A single villain was featured for the good guys to battle- Brainiac.

The 3-packs were meant to jumpstart newbies collections, with 2 of the singles packed in with a main character for 2 3-packs and the rest holding mainly new figures and previous releases.. Superman, Flash and Batman each appear twice in 3-packs. And other leaguers also reappear. Aquaman, who was previously an exclusive became open to retail. A lot of very generic figures appear namely Elongated Man, Starman and Amazo.

Series 2

 New Figures (Using Generic Sculpts): Booster Gold, Hawk, Dove, Atom Smasher, Wildcat, Metamorpho, Waverider, Aztek, Sinestro

These singles follow the previous series releasing matching suits for the heroes (albeit not relevant to the show). The series are smaller, with 2 every subset, and now with official names, unlike the unnamed variants of the earlier line. Red Tornado was color-corrected and released in this line. Aquaman and Starman of the previous line's 3-packs were also rereleased. Amazo was repainted for the singles as well. Lots of the paint jobs on the cardback differ from the actual relase, most notably Planet patrol Wonder Woman and Martian Manhunter.

The 3-packs follow the first line in offering the singles once again packed with other figures. This is especially handy with Hawk and Dove. 2 new packs contain 2 new figures each. Waverider came with 2 main leaguers. If the collector began collecting with the first line already, the repacked figures may start to become a nuisance.
