Where it started
The backstory
ThunderCats premiered in 1985, and LJN’s toy line followed with Lion-O, Tygra, Panthro, Cheetara and their Mutant enemies. Most basic figures used Battle-Matic levers that swung an arm or triggered another movement, giving the toys a shared play pattern without making every body identical.
The line expanded with vehicles, playsets, electronic features and companion packs. Lion-O and Mumm-Ra received light-up eye effects activated by a power ring, while later versions paired characters with small allies. The ThunderCats Lair and Cats Lair vehicles gave the six-inch figures a suitably dramatic scale.
Small accessories drive condition and value. Swords, clubs, rings, capes and companion animals are often separated from their original figures. Check that a figure’s action lever moves freely, but never force a mechanism that has stiffened after forty years.
The familiar favorites
Popular figures to know
These are among the figures that defined the line for the widest audience.
1985 basic figure
Lion-O
The Lord of the ThunderCats carried the Sword of Omens and combined the line’s signature Battle-Matic movement with a heroic sculpt drawn directly from the animated series.
The Sword of Omens, claw shield and power ring are frequently missing. Distinguish the early basic release from later companion-pack variations before matching accessories.
1985 basic figure
Mumm-Ra
Mumm-Ra’s bandaged body, blue skin and red cape made him one of the line’s most distinctive villains. His electronic eye feature created a direct visual link to his animated transformation scenes.
Capes tear and small accessories disappear. Battery corrosion and dead electronics are common, so treat a working light feature as a bonus rather than something to force.
Beyond the obvious
Uncommon figures worth recognizing
Uncommon does not automatically mean priceless. Distribution, completeness, condition, authenticity and current collector demand all matter.
1987 late assortment
Bengali
The white tiger ThunderCat arrived late in the original line with a bold blue-and-white color scheme and a distinctive Hammer of Thundera. Limited shelf time made him less familiar than the core team.
The hammer and small belt details matter. Bright white plastic can show yellowing, so compare color across the torso and limbs under neutral light.
1987 late assortment
Captain Cracker
The robotic pirate Captain Cracker appeared near the end of LJN’s run. His unusual design and short distribution window made him one of the names collectors learn after the better-known heroes and Mutants.
Verify the correct weapon and test moving parts gently. Late figures are often offered with replacement accessories because authentic loose pieces are difficult to locate.

Fun facts hiding in the toy box
Many LJN figures used Battle-Matic levers to swing an arm, turn a waist or trigger another action feature.
Lion-O and Mumm-Ra used a small power ring to activate light-up eyes on certain releases.
Companion-pack versions gave key characters small animal allies, creating another completeness challenge for loose collectors.
Several 1987 figures received much less distribution than the core cast, which is why late characters dominate scarcity discussions.
