The figures stood at a average of 5" tall and well represented each character from the series. LJN produced 3 main series of figures, with many side action figure series with a total of 37 different figures. All cast characters of both good and evil were produced.
This would include the honorable Thundercats team to the vile Mutants and Mumm-Ra. Many of the characters who appeared only a few episodes were also produced. This would include the Beserkers, Rampagers and even Safari Joe. The most demanded figures to collectors are the ones from the last series. These characters are Jaga, Ben Gali, Pumyra and Lynx-o. Each figure was jointed at the neck, arms and legs. LJN did not hold back on their extreme detail of sculpting, allowing each figure to look exactly like the character from the show.
To accompany such a vast action figure line was many vehicles, accessories and monsters. LJN produced 2 playsets, 6 vehicles, 6 accessories & 2 monsters. Of these, the most famous pieces are the Thundertank and the Cat Lair. Most of the other ships appeared in the series while others were created by LJN. There are also 2 other ships called Shuttle Guns that PlayFul created that never appeared in the show. The toughest and most desired pieces are the Cats Lair, and the 2 monsters of the Astral Moat Monster and Tounge-A-Saurus.
Other toys and items were also produced with the 5" series. A 2" series of figures was produced with playsets. Burrger King also ran a Kid's Meal which featured various Thundercats pieces. Eraser, Cake Figurines and more were also produced, keeping a collector busy hunting for quite awhile.
One of the most interesting things about this line is that it was cancelled to early, and LJN had planned many more figures and piece to be produced. These unproduced prototypes were so close to production, that they were featured in catalogs inserts with the toys. The unproduced figures were Red Eye of Lunatacs and two more Beserkers. It is probable that the Lunatacs team was also being in pre production, but no one is sure due to the lack of LJN prototypes. Unproduced ships and vehicles included the Feliner, Luna Tacker & Thunderstrike. Many other unproduced pieces were pictured and slated, and were never released
Most action figure collectors find this line to be one of the best to collect. Collectors are often still searching for the toughest pieces for their collection. These would be the Cats Lair, the Monster, Jaga and Ben Gali. But the toughest and most expensive pieces are the carded gift set packages of Lion-O with Thunderwings and Mumm-Ra with Luna Lasher.
