Fan Casting Thundercats

After the destruction of their home planet, Thundera, the ThunderCats—a group of cat-like humanoid aliens—escape aboard their flagship. Pursued by their enemies, the Mutants of Plun-Darr, they eventually crash-land on Third Earth. Lion-O, the Young Lord of the ThunderCats Born as the heir to Thundera, Lion-O was destined to wield the legendary Sword of Omens and lead his people. However, when the planet meets its tragic end, the young prince is thrust into an unexpected journey of survival. En route to Third Earth, his suspension capsule malfunctions—causing his body to mature into that of an adult while his mind remains that of a child. Now stranded on a foreign world, Lion-O must navigate the trials of leadership, forging his own path while still grappling with the recklessness and innocence of youth. Thankfully, his best friends WilyKit and WilyKat remain by his side, offering companionship and mischief along the way. Meanwhile, the seasoned warriors Cheetara, Panthro, and Tygra struggle to mold him into a worthy ruler while ensuring his survival against the ever-present threats of the Mutants of Plun-Darr.
