The Skeksis scientist is attacked by small animals, during the struggle he falls to his death in a pit of fire.
The chamberlain Skeksis gets his hand cut, a small amount of blood can be seen.
An innocent creature is forcefully strapped to a machine and has its life essence stolen, essentially killing the creature. The creature is then turned into a zombie slave. This is the most violent and disturbing scene in the movie.
In one scene, the Skeksis are eating at a feast. They bite heads and parts off of their food, some of seem to still be moving. Lots of gross sounds.
Two Skeksis duel, trying to bash each other and a stone with weapons. The loser's robes are ripped off violently, and he is banished.
The Garthim are seen fighting with and killing Landstriders (no blood, but it can be upsetting to some). One pair falls over a cliffside.
