Arc 4The Golden Barrier and Beyond
He-El completed the Sevenfold Golden Barrier, defeated Quintessa, and gathered powerful technology while confronting the limits of his Kryptonian body. Back aboard his mothership, he began investigating Kryptonian genetic imprints and preparing to revive Kandor City's people as Zero started transforming the ship.
- Harold exposed the officials’ role in launching protons, while Optimus Prime explained that He-El’s seven barriers could focus sunlight into a devastating beam or charge the AllSpark.
- He-El created Black Suit as his guardian, destroyed General Adolf’s army, and began completing the Golden Barrier as the world darkened and Earth’s rotation stopped.
- Optimus Prime and Sentinel Prime opposed He-El as Sentinel Prime summoned Cybertron, but He-El shut down the Space Bridge and destroyed the Star Harvester’s beam before The Fallen could use it against the barrier.
- Quintessa shattered the completed barrier and attacked He-El, but his defenses overcame her weapons, and he subdued her after she awakened Unicron and Earth retreated from waking.
- Megatron praised He-El’s resolve, and He-El gathered Quintessa’s cells and Cybertronian technology before taking the Star Harvester and Energy Converter for his mothership.
- He-El met Ciri, supplied her with Quintessa’s cells for research, and used the AllSpark to turn Zero into a Transformer that would become the mothership.
- He-El’s attempts to restore Kandor City prisoners to their original size caused their genes to collapse, leading him to discover a psychic Thought Imprint in Kryptonian genes and build a database to replace their genetic information.
- He-El tested the replacement on Chester, ordered Zero to preserve him for observation, and instructed Zero to begin transforming the completed mothership design.
