Below is a quick guide to the core cast — click through to any name for a full history, powers, and trivia.
🦁 Lion-O — The young Lord of the ThunderCats and wielder of the Sword of Omens. Raised and mentored by Jaga, he ages into adulthood shortly after landing on Third Earth and must grow into the responsibility of leadership.
🐯 Tygra — The team's engineer and strategist, armed with the Bolo Whip and the power of invisibility. Rational, methodical, and deeply connected to Third Earth's wilderness.
🐆 Panthro — The strongest and most technically skilled ThunderCat, responsible for building and maintaining the ThunderTank and other vehicles. A veteran warrior and mechanic.
🐈 Cheetara — Gifted with superhuman speed and precognitive "sixth sense" abilities, she often senses danger before it strikes and serves as the team's moral compass.

🦡 Lynx-O — Blind since birth, he compensates with extraordinary hearing and other heightened senses, serving as one of the team's wisest elders.
🧙 Mumm-Ra — The Ever-Living sorcerer and primary antagonist, sustained by three ancient hearts and able to transform from a mummified husk into "Mumm-Ra the Ever-Living" at will.
👹 The Mutants of Plun-Darr — Slithe, Monkian, Jackalman and Vultureman, Mumm-Ra's recurring and often bumbling allies who pursue the ThunderCats across Third Earth.
