The Thundercats on New Thundera receive a 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.
The Heritage 118 118

Cracker's Revenge 122 122
Capt. Cracker and his mechanical parrot Polly land on Way-Out Back and free the Lunatacs and put Bragg and Crownan in one of the train's cages. They plan to go to Third Earth to attack it since most of the Thundercats are no longer on Third Earth. Meanwhile the ThunderCats have learned Cracker escaped and Snarfer and Mandora go to catch him. Bragg has Crownan ride a fire exstiquisher, so he can get into space and get help. Mandora finds him, and the three of them go to Third Earth. Mandora fights with Cracker and the Lunatacs, but is beaten and she and Snarfer are tied to her cycle and sent towards a mountain.

Ma-Mutt's Confusion 124 124
Mumm-Ra has a new device, the Babylonian Barbarian Boiler, that he plans to use on Cats Lair. Ma-Mutt fools around too much and Mumm-Ra banishes him from the Pyramid. Later, the Thunderkittens, Snarf, and Snarfer bring Ma-Mutt back to Cats Lair and then Mumm-Ra fires the Boiler's beam at the Lair, which causes it to start melting. Snarfer makes a communicating device (because Ma-Mutt was trying to tell them about the beam), so they can understand Ma-Mutt. Ma-Mutt starts telling them of the Boiler, but Mumm-Ra sees this and through the Cauldron's magic brings Ma-Mutt back to the Pyramid.
The Shadowmaster 125 125
From the Shadow Realm, the Shadowmaster contacts the Ancient Spirits of Evil (ASOE), telling them of how he captured Lion-O's father, Claudus, just before Thundera blew up. Then the Shadowmaster, through a bad dream, shows Lion-O his captured father and challenges Lion-O to a fight. Lion-O goes to the Shadow Realm through the Book and Sword of Omens, and is able to fight the Shadowmaster as long as the Sword stays bonded to the book. However, the Shadowmaster sends a huge bat to steal the Sword. It succeeds, and then Lion-O becomes very weak in the Shadow Realm. Mumm-Ra meanwhile, feeling like the ASOE will turn against him in favor of the Shadowmaster, sends Ma-Mutt to secretly steal the sword from the bat and put it back near the book. This will be crucial to Lion-O's triumph in this realm.
Swan Song 126 126
An Ecology Inspector (EI) comes to Thundera to inspect the new Cats Lair. His ship uses the SWAN system (Space Way Airborn Navigations) to direct him to planets all over the universe. When he arrives on Thundera, he gets ambushed by Two-Time (see Return to Thundera, Part III, this page). Two-Time uses a hologram to make the EI's ship crash into a mountain, and then when the Thundercats come to rescue the EI in the Feliner, Two-Time uses the hologram again. Lion-O manages to fly around the mountain and lands the Feliner. Meanwhile, Two-Time flies to new Cats Lair in his spaceship, Dome-Down. He actually picks up the whole Lair and keeps it inside Dome-Down.
The Touch of Amortus 127 127
Mumm-Ra orders Amortus, a being he banished to the Land of No Return centuries ago, to destroy Lynx-O. Amortus makes Lynx-O crash in the Thunderstrike, and then he touches Lynx-O's face. The spell from the touch makes Lynx-O feel like he is an outcast, so he leaves to join Amortus in the Land of No Return. The other TCats, Lion-O, Panthro, and Cheetara, go after him. In the Land of No Return, Amortus again touches Lynx-O, this time causing him to turn to stone. The other TCats arrive and try to beat Amortus, but he touches all of them, causing them to start turning to stone. But just as Lion-O is about to turn entirely to stone, he calls the Sword and it breaks them free.
The Zaxx Factor 128 128
Vultureman escapes from exile by hijacking a bookmobile. He finds a disk containing ancient history about two powerful evil forces on Third Earth: Mumm-Ra and his enemy Zaxx. Using this information, Vultureman plots to defeat Mumm-Ra and rule the universe.
Well of Doubt 129 129
The Thundercats use a new Tower signal to guide a Thunderian ship in; aboard are Baron Tass and Mr. Grubber, a devious pair of Thunderians. Later Lion-O sends Torr, Baron Tass and Mr. Grubber to get water, but on the way the Baron stops at the Well of Doubt and gets some of its water. The water causes a person to become very doubtful of his own abilities. When they get back to the Thundercats, Baron Tass gives some of the water to Lion-O. On the way to inspecting the new Tower in the Whisker, Lion-O feels the effects of the water and causes the Whisker to crash. Tass comes back (from getting his Guardsman, giant stone-men), and has them attack the Thundercats. Will Lion-O recover his courage and determination?
The Book of Omens 130 130
Finally Panthr-O deciphers how to use the Key of Omens. He enters the code to open the lock and, suddenly, the Guardian of Omens is summoned and it tells the Thundercats they have 24 hours to present both the key and present four other items to the four places in disgrace (geological disasters) all over New Thundera. All was proceeding correctly except for the key, which was stolen by the evil Mumm-Ra. However, he enters the Book just when Lion-O found him and the battle will go on inside the book. This presented a somewhat legitimate finale for the complete series, with an open ending (which will continue in a short series of comics in an "after future" saga on the year 2002).
