When I statted out Thundarr the Barbarian, I did it as part of my D&D/AE Masters of the Universe/Thundercats crossover. While the Masters were built on a level 20 power scale, the Thundercats were built at around 16th level and Thundarr was built at 10th. My reasoning for this, well ah-ha! I can't remember.
Thundarr was a Barbarian 7/Fighter 2/ Champion of Freedom 1. Ariel was a Sorcerer 9 (though I considered Rogue 5/Sorcerer 4), Ookla the Mok I made as a Barbarian 4/Ranger 4.
Lion-O was a Paladin 3/Unfettered 10/Litorian 3. Mumm-Ra was a Cleric 15/Somnancer 4/Lich. Tygra was a Mind Witch 7/Rogue 7. Cheetara was a Litorian 2/Monk 9/Cheetah Totem 2, with a 100' move. Panthro was a Litorian 3/Unfettered 6/Barbarian 5. Wilykit and Kat were Unfettered 4/Rogue 3. Pumyra was a Greenbond 10. Lynx-O was an Akashic 10. Snarf I never statted out.
He-Man was a Barbarian 10/Champion of Light 10, who transferred his championess to Castle Greyskull. Teela was a Ranger 3/Unfettered 10/Snake Totem 2. The Sorceress was a Druid 20 (just to be contrary). Orko was a Spryte 3/Magister 7. Mer-Man was a Ranger 6/Shark Totem 6/Sahaguin. Beastman was a Bugbear Bear Totem 8/Barbarian 5. Two-Bad was an ettin, Webstor was an Ettercap rogue (I think I might have been going towards Assassin with that one). Evil-Lyn was a Cleric 3/Magister 3/Mystic Theurge 8/Tiefling. Skeletor was a Heightened Greater Undead template Mage Blade 10/Blackguard 10.

Under a Broken Moon: Thundarr the Barbarian Roleplaying Game
"Ariel, Ookla! Ride!"
My favorite thing about this old series was the matte painting backgrounds. It was always the most random assortment of stuff. A luxury liner being used as a wizard's fortress in a swamp, for example. A lot of bad guys tended to set up shop on or near old National Monuments for whatever reason.
Apparently there used to exist a GURPS supplement for this setting, but its pretty obscure. If I were going to run it, I would have to do crossovers with other cartoons like He-Man and Thundercats. And maybe, just maybe, Transformers. Do it all under the d20 banner, most of the stuff already exists. (Moks are half-orcs with cosmetic differences, the Thundercats can all be made as AU litorians and terrig, Slive is just a lizardman and Jackalman is just a gnoll.)
So yeah, Masters of the Universe gets a comic relaunch, a new cartoon, a toyline that when tanks becomes a line of collector's busts, effectively making it the property that won't die... Thundarr gets a wiki page and a GURPS supplement that may or may not exist. Its just not fair.
Hey, I'll admit that viewed with the cool eye of reason, the cartoon sort of sucked. Cheap, sub-Hanna-Barbera animation, a plot that was some sort of derivative Star Wars/Conan knock-off and no engaging storyline beyond "Man in Fur Vest fights this week's poorly animated Monster/Wizard", but I can see past all that. I can see a game where barbarians and sorcerers fight multi-eyed wizards and giant furry bat-snakes on the decks of a partially buried cruise ship in the middle of a post-apocalyptic desert. I can see a world where men are free and Moks roam wild. I can see a world where conflicts of survival and savagery, sacrifice and struggle are played out-- under a broken moon.
By gods, man, can't you see it too?
