List of Thunder Cats Characters - Other Thunderians

Other Thunderians

• Leo (voiced by Will Friedle in the first appearance, Jason Marsden in the second appearance) - Exclusive to the 2011 series, Leo was Lion-O's direct ancestor and Mumm-Ra's right hand. Leo originally believed in Mumm-Ra's ideals for order across the cosmos prior to witnessing the death of the Plun-Darr galaxy. Deciding to engineer a rebellion, Leo gathered the scrapes from what remained from the creation of the Sword of Plun-Darr to create the Sword of Omens to defeat Mumm-Ra. In the aftermath of the Black Pyramid's descent to Third Earth, the Stones of Power taken from Mumm-Ra were split amongst the major races of Third earth with Leo keeping the War Stone with the Cats as the Eye of Thundera.

• Panthera (voiced by Cree Summer) - Exclusive to the 2011 series, Panthera was a Thunderian based on a panther who was among the Thunderians that worked for Mumm-Ra. Being the voice of reason to Leo, she tried to convince him that Mumm-Ra's methods of destruction do not match his goals. It was only after the death of the Plun-Darr galaxy that Panthera aids Leo in planning a resistance against Mumm-Ra. Her fate after the Black Pyramid's descent to Third Earth is unknown (although, given that she and Leo were implied to be a couple, it's possible that she married him and is also Lion-O's ancestor).

• Javan (voiced by Robin Atkin Downes) - Exclusive to the 2011 series, Javan is a Thunderian based on the Javan tiger and is the biological father of Tygra. His ancestors were shunned by the other Thunderians as the Tiger clan branch of the Thunderians were still loyal to Mumm-Ra. When his kin was inflicted with a plague, Javan choose not to turn to Thundera for aid and instead invoke the power of the Ancient Spirits of Evil to save his people. But once learning their price for their survival is the death of his newborn son Tigra, Javan couldn't bring himself to sacrifice the infant to honor their pact and send him away. As a result, the Ancient Spirits bound the souls of the Tiger Clan to the living world as cursed shape-shifting shadow monsters that obey the Ancient Spirits of Evil's every command. Many years later while he and Lion-O were in the mountains, Tygra came across his ancestral home and meets Javan, expressing discontent towards the father who abandoned him. It was only later that Lion-O learned the truth of the curse as Javan tells him not to tell Tygra and get him away from the village before the sun sets. However, upon learning that Caspin and some of his court are going to kill his son, Javan fends them off before the curse takes effect and he mindlessly attacks Tygra. However, Tygra's act of humility broke the curse so both Javan and his kin are able to pass on to the next life. Tygra then inherits his father's whip.
  • Caspin (voiced by Jim Cummings) - Exclusive to the 2011 series, Caspin is a Thunderian based on the Caspian tiger. He is among the tiger-based Thunderians that live in the mountains and serves their leader Javan as his right-hand Cat. When Lion-O and Tygra came across the Tiger Clan's cave, Caspin took them to meet Javan. During this time, Caspin saw an opportunity to end his people's curse as he and his conspirators decided to kill Tygra themselves. However, Javan comes to Tygra's aid and was forced to kill Caspin in self-defense stating that it didn't have to be this way. Before dying, Caspin told Javan that it had to be this way since it was Javan's fault that the entire Tiger Clan was cursed. But as the curse is broken and the Tiger Clan was revealed to have already died long ago, Caspin's sprit body faded away alongside the spirit bodies of the other Tiger Clan members.
