Eclipse

Eclipse is the arch-enemy of TBS. He is a black sun, and a few Kra'lythe work for him, including Genetoes and Minutún.

When Deathsaurus was fighting Yon, Chikato made a missile fired by Deathsaurus explode. The shards of the missile then melted into the floor, and dark spores rose out of the ground, and became Eclipse, who sprayed shadow energy everywhere, destroying everything in his path.

Eclipse appeared again during the Battle of Mata Nui II, and offered Blackout an alliance. Eclipse was then attacked by TBS. Blackout wasn't too happy about Eclipse's offer either, and blasted him with lightning.

While Genetoes and Nosmilo were fighting, Eclipse helped Genetoes by smashing Nosmilo five miles away. Advanced Dal then appeared and attacked Genetoes, but Eclipse crushed him into a fine mist. Eclipse then sent the insides of Dal to an artificial disaster, altered time to make said disaster happen over and over again, and then sent them to a very convenient plane.

When TBS was fighting Vorahk-Kah, Eclipse appeared, and helped TBS fight the mutated Rahkshi.

During the Battle of Lantea, Ynot decided to use the Vahi Cube. Eclipse then appeared and undid all time editing, and then disappeared. This caused a lot of insanity, which meant that none of that ever happened.

Eclipse vanished for many years, leaving his loyal servants scattered and confused. Eclipse was eventually located by Genetoes, woken from his slumber, and taken to Kalta Thaea to join the Kindred of Dawn.
