The Justice League Unlimited card game was available with purchases of McDonald's Happy Meals in select countries. The cards were randomly distributed inside of eight toy cases shaped like a different team member. The toy set debuted in Australia and New Zealand on August 14, 2009.

The game cards measure 9 cm in height. The rules are based on the game of "rock, paper, scissors." There are eight team members and each card has a corresponding game symbol.

There were six toys sold in Malaysia from October 1-29, 2009. Hawkgirl and Wonder Woman cases were not included.

Cards distributed by McDonald's China were printed by The ODM Group in Hong Kong.

Mattel released a Justice League Unlimited trading card set with a 2005 toyline.

In 2007, Justice League Unlimited: Heroes vs. Villains was released in the United States by Carl's Jr. and Hardee's.

In 2007, McDonald's issued a different JLU 50-card game and case set in Latin America.
