Thundercats

Goof: As Panthro drove the ThunderTank, he made the comment to Tygra that it looked like there was a snow field ahead. However, they were already driving on the snow at that point.

Goof: As the ThunderTank followed Snowmeow to find Lion-O, Panthro commented that Cats Lair was half-buried in snow as they drove past. However, the snow didn't even reach the bridge, let alone the lair.

Excalibur defeated the Sword of Omens by stabbing through the Eye of Thundera. This made the sword shrink and fall to the ground and the eye to disappear completely, leaving a solid red circle. Consequently, it made the Thundercat insignias worn on each Thundercat to go blank as well as the Thundercat symbol on Cats Lair. This weakened the Thundercats to the point they all collapsed.

Even though Mumm-Ra takes the disguise of King Arthur, he never identifies himself as King Arthur to the Thundercats. He only identifies himself as a knight sent by Jaga to aid them.

Lion-O rode a saddled unicorn in the joust competition against Mumm-Ra, who was disguised as a knight in a suit of armor.

Goof: After Arthur takes off his gloves and slaps Lion-O in the face with them, he drops them to the ground. In the next moment you see he is wearing gloves again, but then as he walks out of the room he isn't wearing gloves.

Goof: Mumm-Ra said that Lion-O defeated his monster creations with the Sword of Omens then showed a flashback to him defeating the Warbot in Return to Thundera. However, the Warbot was created by the Mutants, not Mumm-Ra. They designed it before they ever arrived on Third Earth.

Tygra is not allowed to help Lion-O in any way, but apparantly that does not include keeping the Mutants away from Lion-O.

Tygra has never used his mind powers before because it is a terrible strain on him and has been storing up all his mental energy for the anointment trial.

Lion-O discovers that his greatest fear is that he'll feel afraid again, like he felt as a boy fleeing Thundera.

Although Lion-O's trial with Tygra is being able to overcome Tygra's mental powers of illusion, they end up in a physical hand to hand fight, like Lion-O did with Panthro in the trial of strength. He did not, however, fight hand to hand with Cheetara or the ThunderKittens.

Tygra's Powers: (First Use) Mind Power - the ability to create illusions so that others see what is not really there.

This is the second time the Thunderkittens get trapped out in a storm (see The Rock Giant). They apparently forgot Lion-O's earlier advice to them not to hide under a tree in a thunderstorm. Like before, the tree they tried to hide under was struck by lightning.

Goof: In Return to Thundera, it was discovered that the Warbot's only weakness was a hole in one foot where its energy supply was hooked up. Firing weapons on the the robot would do no damage. However, in this episode, the ThunderTank managed to shoot holes in the Warbot to destroy it.

Previously the War Machine took all the Thundercats to defeat, but this time Panthro just shot some stuff out of his nunchuks at it and it fell over and was destroyed.

Goof: Lion-O opened the Eye of Thundera for the camera, but in the next shot the eye was closed. But after that, the Eye was open again as he shrunk the sword back down and closed the eye.

Mumm-Ra summoned out of the sand various robots and war machines. The War Machine was from Turmagar the Tuska and the Warbot was from Return to Thundera. Also present were the Driller and a Mechenosect.

The recorders make sounds like a camera taking a still photograph, yet it plays back video footage.

When Lion-O summoned the Thundercats, the Eye of Thundera gave all of them, except Snarf, the strength and ability to overcome the effects of the bracelets.

Goof: Just before Lion-O summons the Thundercats with the sword and is trapped in a pink beam being shot at him from Mumm-Ra's hands, the Sword of Omens is already full size with the Eye of Thundera showing. Yet just before that moment and just after when he starts the call, the sword is properly small with the Eye closed.
