Season 1 comprises 65 episodes - a standard number for animated series at the time, as it allowed the series to be shown every weekday for thirteen weeks (one full broadcast season). The series' two-part pilot episode debuted starting January 23, 1985, with airdates varying by market; WTOG aired it on January 23, while WNEW aired it on February 1. The series subsequently began airing in its regular weekday time slot on September 9. In 1986, the series returned for a TV movie, ThunderCats - Ho!, which was subsequently aired as five separate episodes worked into the continuing rerun rotation of Season 1. The second season, which produced sixty episodes, was broadcast as three seasons between 1987 and 1989. Each broadcast season began with a five-part miniseries that established the new concepts and characters that would play into the events of the season that followed. Most online episode guides for the series list the episodes in two seasons as they were originally produced.
LJN produced the ThunderCats action figures from 1984 to 1987. The ThunderCats line was based on the animated series which was actually created in 1983. Due to difficulties, it would not air until 1985. Each figure had an action feature of some sort, and the line also included a unique "laser" light-up feature that interacted between the Cats' Lair playset, some figures, and some accessories. Lion-O's eyes and Mumm-Ra's eyes would illuminate when a special battery-powered key ring that came with the figure was pressed into a slot in their backs. PVC companions were packaged with some figures in 1986, including WilyKat with Tygra, WilyKit with Cheetara, Snarf with Lion-O, and Ma-Mutt with Mumm-Ra. The PVC companion figures were also produced as full size articulated figures.
LJN did produce a few variant figures including the young Tygra version and the silver rat-eye daggers for Rataro. There are also a few slight color variations of Lion-O, such as red and orange-haired versions. The third series of figures from 1987 are harder to find along with the Tongue-A-Saurus and Astral Moat Monster. Driller and Stinger are the toughest figures to track down; Stinger's wings are very fragile, making it next to impossible to find a loose, complete figure.
