‘’Return to Thundera, Part 5 is the one hundred fifteen episode of ThunderCats (original series)


After another earthquake caused by Mumm-Ra ruins the new Cat's Lair construction site, the Thundercats go to see Jagara and confront Mumm-Ra. Unfortunately, Mumm-Ra puts up a force field over entrance.

Jaga appears to Lion-O and tells him to use the Eye of Thundera to get to Jagara and the Gyroscope. Lion-O does so and battles Mumm-Ra, who throws him into the bottomless pit underneath the Gyroscope. However, Lion-O manages to throw his grappling hook to the top, which pulls him back up. Lion-O then shines the signal, which goes through the force field.

All the ThunderCats leap through the signal which takes them through the force field. Together, they fire all their weapons at Mumm-Ra and he is defeated. But before he leaves, he breaks the cord that holds the Gyroscope above the pit and it falls through. Now, New Thundera is literally falling apart. Lion-O however throws the sword in the spot where the Gyroscope used to be and calls upon the Thundercat Ancestors for help. The sword starts spinning and creates a new Gyroscope, thus New Thundera is saved.
