Lion-O wakes up from an awful nightmare he has been having about leaving Thundera. He remembers leaving some of his fellow
Thunderians on Thundera because the ship could not stay any longer. Jaga appears to him and explains that they did not perish,
and that they are on third earth. Anxious to find them, Lion-O asks Cheetara to use her psychic powers to find their location.
Mumm-Ra, overhearing this news, send the Berserkers to capture the Thunderians, and bring them to him. He captures them, and
has them sent to Fire Rock mountain (otherwise known to the thundercats as thundrainium). Weakened by the thundrainium, the
thunderians are hopeless. Lion-O, unable to get past the thunrainium to save them uses the power of the star of thundera to cancel
the effects of the thundrainium. Mumm-ra sends Grune to stop Jaga from getting the power of the star for Lion-O, but Grune fails.
After giving the stars power to Lion-O, Mumm-Ra manages to steal it from him. Mumm-Ra, trying to possess the stars powers,
instead gets destroyed by the stars power. Lion-O saves the thunderians, and anoints them as Thundercats. Bengali, the white
tiger, Pumyra, the female puma, and Lynxo the blind lynx.
Mumm-Ra Lives! (5 part series)
Part I
The Thundercats think that they have destroyed Mumm-Ra for good. Little do they know that he survived. He returns to his tomb
with the help of Ma-Mutt, and is too weak to do anything. So he transforms Ma-Mutt into an image of himself, and sends this image
to order the mutants to release the Lunatacs.
Part II
The Lunatacs have been freed by the mutants. Mumm-Ra joins forces with them to destroy the Thundercats, and after doing so,
they would rule third earth together. The Lunatacs meet the Thundercats in battle, and prove to be much stronger than them. In
fact, Tug-Mug, one of the Lunatacs manages to break the sword of omens in half. Bengali however manages to reforge it since
he is a Thundarian Blacksmith.
Part III
The Lunatacs build their fortress with the help of the brute men. They call it Sky-Tomb, and not only is it powerful, but it can travel
through the air. It is a mobile fortress. The Thundercats ask the Berbils to help them build a new structure called the Tower of
Omens, that would help them easily locate the position of Sky Tomb, and stop the Lunatacs as fast as possible.
Part IV
Young Snarfer, Snarfs nephew, arives on third earth. His ship has gone off course though and landed in territory of the Lunatacs.
The Lunatacs manage to capture Snarfer, and the Thundercats must venture into Darkside to save young Snarfer so he can work
in the Tower of Omens.
Part V
Lion-O, Panthro, Tygra, and Pumyra set out to Darkside to free the slaves the Lunatacs have imprisoned. In doing so, they get
captured. Cheetara and Lynxo set out to Sky Tomb to save them. The Thundercats see Mumm-Ra for the first time after his "death"
at Sky Tomb, and discover that he cannot be harmed by his own reflection anymore. The ancient spirits of evil have made him more
powerful when they revived him. They Thundercats manage to escape, and leave the Lunatacs fighting amongst themselves.

The Mad Bubbler
The Mad Bubbler, an ancient creature of third earth who lives in an old Thundrilium mine on hook mountain has the power to turn

Lunatacs to fight against each other, and afterwards Panthro, Tygra, and Cheetarah. They fall under the bubblers power and begin
fighting each other to the death. Lion-O, observing these occurrences through the sword of omens finds out from Jaga that snarfs
are not capable of evil. He summons Snarf and Snarfer and tell them to retrieve the Thundercats from the mine so that they can be
returned to their normal selves.

for their ship, use excersise machines to power it up. They capture the other Thundercats and force them to workout on the
machines to power up the ship. The Thundercats manage to overwork the power supply, and escape from Sky Tomb. Back in the
caverns, Snarf manages to get the sword of omens to Lion-O with his tail, and they escape and return to third earth.
Thunderscope
Back visiting their old wreckage site, Lion-O and Snarf stumble upon the Thunder-scope, a legendary thunderian telescope that
locates lost thunderians, and their belongings. Mumm-Ra, interested in the Thunder-scope so he could find the treasure of thundera,
ambushes Lion-O. He actualy kills him in this scene. Before Lion-O dies, he manages to take out a lens from the Thunder-scope so
Mumm-Ra could not completely use it. Jaga appears to Snarf, and Lion-O's dead body, and revives him. Mumm-Ra comes back for
the missing piece, and Lion-O has to stop him.

Dragon possess the power to entrap people in its stomach. The legend says that Hachiman's ancestor gave the dragon to his wife as
a marriage gift, and since her father was so against their marriage, he put a curse on the dragon and it engulfed Hachiman's
ancestor. Jaga freed the him, and he gave the dragon to Jaga for safe keeping. Now, the Thundercats have found the Jade Dragon,

distress signal from Thunderian refugees trying to find their way to New Thundera. The Kittens are left alone with Snarf on at the
New Cat's Lair, and Lion-O and Snarfer are out constructing an early warning device (I guess for weather purposes). The rest of the
Thundercats seek out the refugees in space. When Wily Kit and Kat strike water, they accidentally unleash a monster that Jaga
trapped in the underground lake centuries ago. Frogman, with aquatic powers, tries to sink the New Cats Lair. Lion-O however
re-traps Frogman in his watery prison.

destroy the Golden Sphere of City.

Jaguara cannot work New Thundera's Gyro on her own. The Thundercats order a robot to aid her in running the Gyro. Screw Loose,
a robot who specializes in Gyros, comes to New Thundera. Mumm-Ra manages to mess up Screw Looses brain so he becomes
destructive instead of helpful. The Thundercats must help Jagara get Screw Loose under control, before the entire planet is
destroyed (again).
Malcar
