After seeing Darththomas81's "Lion-O AKA Cavecat Custom Action Figure" I wanted one for myself. I love the concept & backstory. So I asked him if I could steal his concept and he said "Sure mate!". So thanks for that Darththomas81!

Here is his backstory (by/based on Dartthomas's)

After the Thundarians escaped their dying planet they went into stasis. During their stasis Jaga, (who had stayed awake to pilot the ship), became very old and very frail. It was inevitable that he would soon pass. After he died the ship was left pilotless and crashed into a red planet just near third earth. However, before the ship crashed the stasis pods were ejected into space. Each pod scattered from the stricken ship in different directions. Lion-O's pod was sent hurtling to the outer reaches of the galaxy where it was sucked into a worm hole that sent him back in time, way back. Finding himself alone and friendless in a savage land of dinosaurs he soon realised his already muscular frame would not be enough, hunted daily by lizards the size of the thundertank he had to rely on his speed and agility. However, his speed and agility was not enough for him to hunt the kind of prey that was available. So, he set about building himself up and he soon grew to hulk like proprtions. Lion-O has now earnt himself the reputation of the most fearsome being on this planet and he is no longer hunted, he is the hunter. He hopes one day that he and the rest of the Thundercats will be reunited and fight for the thunderian code once again.

For my Savage Lion-O I used a Marvel Select Ultimate Hulk. Everything else was sculpted. Painted with Revell model paints and thats about it.
