Later in an alternative event of episode 11, Lelouch as Zero was in a middle of a battle against the Chinese Federation for kidnapping Tianzi and won after exposing the eunuch's plot and had them killed in their command ship. They are later confronted by the Britannian military forces led by Schneizel, along with the Knight of Rounds, Suzaku, Gino, Anya, and Luciano in their respected Knightmares. As the two sides prepare to fight each other an unknown black hole suddenly appeared and sucked all sides in, except for the Black Knight's flagship, Ikaruga, and a Britannian carriership with Schneizel inside, who both manage to escape.

Lelouch, along with Kallen and C.C., has arrived in Planet and suddenly appeared in a desert, where they witness a traces of a bonfire being spotted a ruined city. The group later entered a ruined dome, where they were approached by an unknown unit, later revealing themselves to be Sousuke Sagara, Melissa Mao, and Kurz Weber from the Full Metal Panic! series in their respected Arm Slave.

They later meet a second group consists of mechas from both Super Dimension Century Orguss and Overman King Gainer, with Olson D. Verne in his Orguss II unit speaking on behalf to join forces, in exchange for information. Lelouch who is also speaking on behalf of his group accepted his offer.

As the group come to a truce and decide to work together, they later encountered Suzaku, in his Lancelot, along with the Avalon. Lelouch tried to convince him that they are not here to fight and asked to cooperate with them, but Suzaku refused and prepared to attack, but was interrupted by the arrival of a group of SPR forces and a defense arms. The girl in the defense arm introduces herself as Spring One and offers to guide them through this world because she feels sorry for them. However she is easily seen through by Zero, and he rejects it. In reply, Spring began the attack on Zero's group, while the group was ordered by Zero to defend the Avalon.

As a large number of SPR fleet arrived after Spring's escape, the SMS Macross Quarter from the Macross Frontier series arrived, along with the Ark Alpha, and wiped out all of the remaining fleets. Lelouch and the group were surprised by its transformation and was contacted by Jeffrey Wilder, Captain of the Macross Quarter, confirming Lelouch's suspicion as their allies and decided to join them with the group, along with Suzaku who also agreed. Lelouch and his group had eventually sided with Autumn Four and boarded on her ship, where he had met with Suzaku, along with Lloyd and Cecile, who had also side with Autumn, leading both to had a small quarrel but eventually put their differences aside.

Later in the briefing room, after Autumn confessed to memory loss, he met with Autumn alone and revealed himself as Lelouch to her and used Geass on her to unlock her memories for answers, but was shocked when it did not have any effect on her. Autumn, aware of what he was doing, tells him that he and the others will be ready for their next mission and left. Lelouch has started to become fascinated with Autumn as his Geass did not work on her. Later in one of the missions, Lelouch and the others fought against Spring One in her Core unit, Sea Plant, which Autumn later delivered the final blow in her Core unit, Alpha Heart, causing Spring to escape. With many of the group starting to have doubts about Autumn, Lelouch question if she is really human, which she confirmed is true - that she was an android.

Later the Ark Alpha crew arrived at a Geo Plant facility station, and Lelouch was surprised by the appearance of Bonta-Kun, which took down two large Icon's easily. After passing through different levels, they encountered Cynthia Lane of Trans-Siberian Railway is blocked with Asuham Boone in front of them, from Overman King Gainer, and Zero notice Cynthia has lost the will to fight, leading Asuham Boone to attack and was defeated. This led Asuham to retreat, and the crew let Gainer convinced Cynthia to join them.

Crew of Ark Alpha succeed in the invasion to the centre of Geo Plant. However, Anti-U.N. forces and Summer One waited for them there. Summer One speaks the reason why there is no human in planet Area to them before the fight. Autumn believes that Ark Alpha is the hope of mankind, but Summer confirms that the humans have been destroyed at the Seasons hands, which has shocked the rest of the Ark-Alpha crew and begun attacking him in his Geo Breaker. As Summer One made his escape after his defeat and the collapse of the Geo Plant, Autumn went and secures data from Geo Breaker and request everyone to escape, believing that it would help them. Impressed with her determination, Lelouch assisted her and protected her from the falling debris with the others clear a path for her escape.

Near the end of the game, the rest of the group fought once more against the first three Seasons in their respective Plants. Winter then activated the ACE system, but was surprised that it would not work, and the group was later surprised as Winter was taken over an unknown entity, who revealed himself as Doctor Shiki, whom they then fought in Winter's Core unit, Four Seasons.

As the group manages to defeat him, Doctor Shiki escape and both Autumn Four and Lelouch went after him. As Autumn was about to kill him, Doctor Shiki revealed that his death will destroy Eria, which Lelouch then confronts him, thinking his death would save Planet Area, and realises Doctor Shiki's mind is connected to Winter's artificial brain. Lelouch then used his Geass on Doctor Shiki to suffer an eternal nightmare, causing him to suffer an immediate breakdown and collapsed, and escape with Autumn Four. System ACE was later activated and Autumn Four suppressed the black hole being expanded and opens the gate, leading the group to return to their own world. As Lelouch and the others return to their world in the Chinese Federation, he requests to Suzaku that the two would speak. The two had a brief conversation and went to there separate ways, with Lelouch knowing that they will be enemies again.

Nightmare of Nunnally
Lelouch receives a different Geass ability in the Nightmare of Nunnally spin-off series as a result of his near-death during the Britannian attempt to recapture C.C. Instead of the ability to control others, he receives invulnerability granted through a suit of black armour, transforming into a more heavily armoured version of Zero. In the armour, Lelouch can fight on par with multiple Knightmares in single combat. As in the original series, C.C. often serves as his body double, but here is able to manifest the same Geass ability and fight on the same level as Lelouch. With his new abilities, Lelouch forms a different Black Knights and leads them directly in battle instead of planning strategies from the rear, though his fighting ability allows him to achieve the same ends. Lelouch's fighting skills are impressive as his fighting style matches that of Suzaku's. The ability of Lelouch's armor functions almost the same as a Knightmare Frame, such as his cape which can create multiple sharp black whips similar to the Mark Nemo's Blonde Knives. Another ability it possesses is a system called D.O.M. Hostia or the D.O.M. system, which has the ability to control and disable a Knightmare. He also has the ability to summon his own personal Knightmare Frame, Gawain.

When Suzaku enrolls as a student at Ashford Academy, Lelouch becomes angry at the teachers and student who look down at Suzaku for being an Eleven. Growing more annoyed at Suzaku preventing him from help with the latter, fearing that his reputation could be affected and his identity as a Britannian Prince exposed.

He later comes across the mysterious Lancelot, later discovering to his shock that it was in fact Suzaku.

Code Geass: The Manga
The manga follows the same basic plot as the anime, but with several differences. For one, Knightmares do not exist. As for Lelouch's character, he is still the same as he was in the anime. He takes on the identity Zero, but largely focuses on his activities with the Black Knights. He shares the same relationship with Kallen in the anime with her admiration for Zero and disgust for Lelouch. As such it is often considered an alternate universe due to the extreme differences. Lelouch even meets Euphemia much sooner in the story.

The Miraculous Birthday
In a special Code Geass Picture Drama episode, Lelouch reappeared on December 5 for Ashford Academy's school festival, helping Rivalz, now school president, along with Rolo and Kallen. He later met with Suzaku, who brought along Nunnally, Shirley, but was surprised that C.C. appeared with them. However a battle erupted in school grounds by the Neo-Chinese Federation, led by former eunuchs, and took everyone hostage.

The rest of the group escape to the clubhouse and discuss their situation in the student council room, but Lelouch however thought of a plan to defeat them with everyone's help. Both he and C.C. went out to confront the two soldiers, and had used his Geass on them to lock themselves in the bathrooms, rather than having them kill each other, preventing any bloodshed being made in the school. Lelouch later rendezvoused with Rolo, along with the group and walked down the south hall. He received a call from Kallen, but was shocked that it was the eunuch and had captured both Suzaku and Kallen and request that they meet in the school's chapel. The group arrived and confronted the eunuchs, demanding to know where Kallen and Suzaku are, to which he revealed that they are in a vase. The group did not take it seriously, but C.C. recognize it and reveal it to be a mystic item known as the "Thousand-man Silver Vase", an item Charles had collected. The leader then used it on Nunnally and C.C, to which Lelouch and the group were shocked that their souls were absorbed and their body was left unconscious. While Lelouch figures out a way to defeat him, he realises that the vase only absorbs one soul per use and decides to don his Zero persona for his plan. As the eunuchs prepares to use his vase, Lelouch ordered Rolo to use his Geass to stop time, then Lelouch used his Geass on the students to wear the mask of Zero and got Rolo to release his, causing the vase to overload and explode, releasing all the souls and returned to their bodies and defeating the eunuch.

In the aftermath, Lelouch prepares to say goodbye as his body starts disappearing and left an inspiring speech for each of them before saying thanks to everyone.

Nunnally in Wonderland

While narrating the story, he is shown with different reactions in certain parts of the story. For instance, he is seen getting mad when the Cheshire Cat (C.C.) tries to convince Nunnally to stay in Wonderland. After finishing the story, he is confronted by the other characters for using them in his story while he did not do anything, after which they surround him and dress him up as the Mad Hatter.
