[1][2] In addition to the event, a one-shot issue titled Power Rangers Unlimited: Heir to Darkness was released on March 31, 2021.

and Hasbro announced "The Eltarian War" as the second part of the event, being written by Ryan Parrott through issues #13–16 of the ongoing Mighty Morphin and Power Rangers series, between November 2021 and February 2022.

[5] According to Parrot, this event continues where "Unlimited Power" left off, and it tells more about Lord Zedd's backstory, as well as the introduction of a new Blue Omega Ranger.

[6] In the mainstream universe, after the defeat of Kiya and the Anointed,[A] Lord Drakkon (who survived his time within the Morphin Grid) is sent back to Earth, where the Power Rangers locked him up in the Command Center.

Lord Zedd reunites with his minions in order to recruit a clone of Rita Repulsa and use the Chaos Crystal to turn them into his own "Dark Rangers".

Then the mysterious figure appears, and reveals itself as a member of the Empyreals, a race that has decided to wipe out the universe entirely, and is responsible for murdering the Red Emissary.

After a hard talk, Slayer gets the trust of the Coinless, but they are attacked by zombies led by the ghost of Rita Repulsa, who was summoned by Trini Kwan as a desperate measure to end their war, to no avail.

As she releases a man inside a Ranger armor, he desperately reveals her actions activated a signal, sending a message that allows an army of space monsters to conquer the world in case Drakkon was defeated.

Retreating from that battle, Zordon discovers that the new Green Ranger works for Promethea, leading him to have an argument with Grace Sterling.

When Skull gets unconscious for the battle, Bulk confronts Candice about keeping secrets from them, which leads her to go to Zordon and expose her true identity as Zenya of Eltar.

The Power Rangers try to deal with how Zedd could chase their families if their identities were revealed, until Grace calls for help to prevent the military forces from destroying the city.

Back on the Moon, Lord Zedd releases Zelya, but in exchange, he reveals her his true identity as Zophram, the former Supreme Guardian of Eltar, who got badly wounded after being rejected by the Zeo Crystal due to a protective incantation.

[20] After the outbreak, the Omega Rangers are in the run from bounty hunters hired by Zordon, while searching for the Shattered Grid with Drakkon's help, when the ship was powered down.

The Omega Rangers think it was Drakkon doing it, but it turned out it was caused by the Horrid, a race of vampire-like creatures that suffered their transformation after trying some experiments on the Morphin Grid that lead their planet to be destroyed.

Back on the Spectrum, Xi discovers Drakkon has been working with Zartus the entire time, in an attempt of freeing himself and regaining his powers.

Unbestknown to Astronema, she had his memories altered, making her believe her family was murdered by Power Rangers for allegedly serving Dark Specter.

After winning her death match against Darkonda's protégée, Astronema was chosen as the new Princess of Evil, as she gives orders to travel to Onyx, where the Omega Rangers are.

After escaping from Vile' armies, the Phantom Ranger takes Fienna and Rita to the Masterforge, where Grid Energy is collected.

Back to his current research, the Phantom Ranger found out Dark Specter has already begun to cross over from his dimension, and his presence is even more dangerous than the Empyreals' threat.

While Tommy and Aisha visit Grace, Matthew and Billy on Promethea, the Sentry Force Four attempt to capture Adam, Kimberly and Rocky.

When Zordon returns to the Command Center and meets Billy, they are interrupted by Zartus, who reveals that he was responsible for the spell on the Zeo Crystal that caused Zophram/Zedd's wounds over his body.

[26] After Drakkon destroys most of Xi's body, he leaves aboard the Spectrum, abandoning the Omega Rangers in the process, while the Empyreals initiate the planet's destruction.

Adam, Kimberly and Rocky confront Sentry Force Four before retreating to Promethea, where they reunite with Grace, Matthew, Tommy and Aisha.

While trying to get Xi back online, Trini finds distress calls from Earth, with the last message being sent by Tommy, who asks them for help while fighting the Eltarians around Promethea.

Back in the Command Center, Alpha-5 uses the security protocol that he previously used on Drakkon against the soldiers to save Billy and himself, but Goldar, Finster, Squatt and Baboo attempt to claim Zordon's chamber under Zedd's orders.

At the beginning, Zordon reconsiders how his loyalties led to Zartus' victory, but Billy convinces him to keep fighting and learn from his mistakes.

Goldar, Finster, Squatt and Baboo return to the Moon with Zedd, so they can all depart to another location before archiving their final plan against the Rangers.

"[40] The second part titled "Darkest Hour" debuted in August 2023 to commemorate the thirtieth anniversary of the Power Rangers franchise.
