The ThunderCats original series will forever be near and dear to me as one of the first cartoon series I can claim to have fully watched. Originally broadcasted in 1985, the series is a creative mixture of the traditional heroic storytelling set in a fantastical sci-fi world with alien cat-like humans saving the day, known as the ThunderCats.
The Sword of Omens
Having to escape their dying home planet of Thundera and avoid the relentless attacks from the Mutants of Plun-Darr, the ThunderCats are the surviving nobility of the Thundereans who are tasked with protecting the Sword of Omens and Eye of Thundera. The eye being the source of the species amazing powers is embedded in the blade of the Sword of Omens, which can only be used by the Lord of the ThunderCats.
Due to the circumstances of the evacuation, this duty fall upon the young heir Lion-O who is barely old enough to understand the circumstances of their fleeing Thundera. He is accompanied by several other nobles including Jaga the Wise, analytical Tygra, incredibly fast Cheetara, Panthro the loyal warrior, the twins WilyKit and WilyKat, and Lion-O’s nursemaid/protector Snarf. To ensure the safety of the ThunderCats, Jaga tasks himself with piloting their ship to the nearest habitable planet, Third Earth. In doing so, he dies of old age while the rest of the ThunderCats survive through the journey with the almost totally anti-aging suspension capsules.
