LJN was an American toy company and video game publisher. It was founded in 1970 by Jack Friedman and ran until 1994 when it was closed down and dissolved into Acclaim Entertainment. In the early 1980's, LJN was contracted to manufacture the Thundercats toy line. Unlike many other toys being produced at that time, the LJN Thundercats toy line was unique due to almost every toy having some sort of a "Battle-Matic" action. This feature, which made the toys extremely popular among children, was also employed by LJN in its previous toy line, Advanced Dungeons & Dragons.
