Warning: Contains SPOILERS for Invincible season 2 and the comics!

Summary

• Mark Grayson's blue suit arc is a major storyline to expect in Invincible season 3, signaling a darker path for the character.
• Oliver's transformation into Kid Omni-Man is likely to happen in the season, following the comics closely.
• The introduction of Powerplex as Invincible's new arch-nemesis sets the stage for intense conflict and revenge in season 3.

Invincible season 2 has finally come to a close, but there are still many more arcs to explore, so here are 10 Invincible storylines from the comics to expect in season 3. Although the Invincible TV show has added in some original elements, many of the most significant storylines in the Invincible show are ripped straight from the comic series, with the show following the order and pacing of the comics. Because of this, it is already clear that some specific storylines will appear in Invincible season 3, and these 10 are the most likely candidates.

Invincible season 2, part 2 is finally here, with the highly anticipated continuation of Amazon Prime Video's critically acclaimed adaptation of the superhero comic series of the same name now released in full on the streaming service. Invincible season 2, part 2 picks up right where Invincible season 2, part 1 ended, with Mark Grayson returning home from Thraxa in order to take on more Earth-based threats. The Invincible season 2 finale finally saw Mark and Angstrom Levy face off, setting the stage for an even more exciting story to be told in the third season of Invincible.

10 Mark Grayson's Blue Suit

Mark Gets A Makeover

One of the most obvious storylines for Invincible to tell in season 3 is Mark Grayson's blue suit storyline. In the comics, Art makes Mark a new blue and black suit upon making the suit for Kid Omni-Man, with Art explaining it as a change of pace. Mark sticks with the blue suit for a while, with this being reflective of the character going down a much darker path.

Although the blue suit was teased throughout the season, Mark didn't get the blue suit in Invincible season 2, with the finale ending just before the point where Mark gets his superhero makeover in the comics. Because of this, it is fully expected that Mark will get his blue suit early in Invincible season 3, paying off the teases of season 2. The blue suit arc could be the main focus of the batch of episodes, as Mark eventually returns to his yellow and blue suit after rejecting his darker path.

9 Oliver's Transformation Into Kid Omni-Man

Oliver Follows In His Father's Footsteps

Alongside Mark Grayson's blue suit arc, it is also almost guaranteed that Invincible season 3 will contain Oliver's transformation into Kid Omni-Man. In the Invincible comics, Oliver comes to Earth from Thraxa as a baby, with his rapid aging allowing him to catch up to Mark pretty quickly. Upon becoming a teenager, Oliver decides that he wants to be a superhero like his father and his dad, with him using his Viltrumite powers to become Kid Omni-Man.

In the comics, Oliver Grayson reveals his superpowers to his brother in the issue directly after Rus Livingston and the Sequids are defeated by the Guardians of the Globe. Since this arc appeared in Invincible season 2, Oliver Grayson will probably get his powers soon, meaning that the Kid Omni-Man arc is almost guaranteed to happen in Invincible season 3.

8 The GDA's Implementation Of ReAnimen

Cecil Tries A New Approach

Another major storyline that occurs in the wake of Angstrom Levy's villain arc is the use of ReAnimen by the Global Defense Agency, something that shakes up the world of Invincible. In the comics, Cecil hires the villain D.A. Sinclair to create cyborgs out of dead bodies, with Cecil using the ReAnimen as foot soldiers. This decision causes some conflict between Cecil and Mark, something that will probably be explored in season 3.

Cecil's use of the ReAnimen for the GDA was heavily teased throughout Invincible season 2, with Cecil even talking to Sinclair about the ReAnimen several times throughout the season. Although they weren't ready yet, they will probably be ready in Invincible season 3, with the GDA's updated ReAnimen playing significant roles in several key storylines, including the truly epic Invincible War saga.

7 Allen & Omni-Man's Prison Escape

An Exciting Invincible Team-Up

The cosmic side of Invincible will also receive some more attention in Invincible season 3, with Allen the Alien and Omni-Man's prison escape possibly being the focus of the very first episode. In the comics, Allen the Alien meets Nolan in a Viltrumite prison, with the two bursting out and returning to the Coalition of Planets in an attempt to start working for the Coalition during the Viltrumite War.

The latter half of Invincible season 2 saw Allen attempting to track down Nolan, with Allen letting himself get kidnapped by the Viltrumties and finding Nolan in prison. The very last scene in Invincible season 2 involved Omni-Man itting that he missed his wife, hinting that he has fully turned against the Viltrum Empire. Because of this, Allen and Nolan will most likely burst out of the prison early in season 3, working together to escape from their Viltrumite kidnappers.

6 Gathering The Viltrumite Weaknesses From Omni-Man's Books

Using An Unexpected Ally

After escaping the Viltrumite prison in the Invincible comics, Allen the Alien and Nolan Grayson head to the Coalition of Planets homeworld in an attempt to begin preparing for the Viltrumite War. Thadeus sends Allen and Nolan to track down Viltrumite weaknesses from across the galaxy, with them using the books that Nolan wrote on Earth to find them. These intergalactic adventures allow Allen and Nolan to grow closer, setting up the Viltrumite War storyline.

Invincible season 2 already introduced Omni-Man's sci-fi books, with Allen going to Earth to scan them for weaknesses before returning to space. Several Viltrumite weaknesses are highlighted in Invincible season 2, with these important setups being used later in the series as weapons against the Viltrumites. This is the very next thing that Allen and Nolan do after breaking out of prison, meaning that it will most likely appear in season 3 as well.

5 The Timeline Of Tyrant King Immortal

He Goes Down A Dark Path

One of the weirdest storylines from the Invincible comics that could appear in season 3 has to do with time travel, with Mark Grayson taking on the tyrannical king of Earth, The Immortal. In the comics, Mark repeatedly runs into two time traveling bandits, only for them to reveal that they are actually trying to save a future Earth from a tyrant king. Mark goes to the future to help, only for him to realize that this tyrant is actually the former Guardians of the Globe member the Immortal.

While this storyline doesn't have much to do with the broader overarching story of Invincible, it is a fun side adventure that could fit into Invincible season 3. Although it may get cut for time, its position in the Invincible timeline means that it will probably appear in season 3, allowing for more Invincible time-traveling adventures.

4 Multi-Paul's Fight Against The Guardians

Forcing Another Superhero's Hand

The death of Dupli-Kate is a major turning point in Invincible, with it being the catalyst for several future storylines. The most significant of these occurs when Kate's brother Multi-Paul shows up to fight the Guardians in an attempt to avenge his sister. This epic fight causes a lot of destruction, but it also forces Kate to reveal that she is still alive to the world.

Dupli-Kate's purported death was one of the saddest parts of Invincible season 2, but her grand return will probably happen in season 3. Invincible season 2 has already revealed that Dupli-Kate is still alive, with The Immortal meeting her hidden clone in a cabin. Thus, it shouldn't be long until more characters find out that Kate is still alive, with her returning for the Multi-Paul storyline in Invincible season 3.

3 Mark's Falling Out With Cecil

Cecil Makes Some Drastic Choices

Although Mark Grayson and Cecil have never exactly seen eye to eye, the two have a major falling out after the events of Angstrom Levy's kidnapping of Debbie and Oliver, meaning that this could occur in Invincible season 3. In the comics, Cecil tries to rehabilitate people like D.A. Sinclair and Darkwing while also trying to get rid of people like Wolf-Man. Mark disagrees with these practices, causing him to have to fight Cecil's ReAnimen before quitting his job at the GDA.

Invincible season 2's introduction of Oliver and set up of Mark Grayson's blue suit arc set the stage for Mark and Cecil's big conflict to occur in season 3. Mark is questioning his role as a superhero and many of Cecil's actions, with Mark's decisions to lash out at several points eventually leading to his falling out with Cecil in the near future.

2 Invincible's New Arch-Nemesis, Powerplex

An All-New Street-Level Threat

Another new street-level villain is set to appear in Invincible soon, with this being Mark Grayson's new arch-nemesis, Powerplex. Powerplex is a character who has the ability to absorb and reuse energy, with him hoping to kill Mark Grayson as revenge for Powerplex's sister being a victim of Mark and Nolan's Chicago fight. However, Powerplex's plan backfires and leads to the death of his wife and child, making his hatred for Invincible only grow stronger.

Powerplex is one of the most complicated side characters in Invincible, and his first appearance and encounter with Mark will most likely occur in Invincible season 3. Powerplex is a recurring character throughout a significant chunk of Invincible, meaning that season 3 could set him up for even bigger roles in future seasons, including his role on a new GDA superhero team.

1 The Invincible War

Angstrom Levy's Climactic Plan

The biggest Invincible storyline that will undoubtedly appear in season 3 is the climactic Invincible War. In the comics, Angstrom Levy secretly survived his death at the hands of Invincible, with him disappearing to plot a new scheme. Angstrom Levy rounds up evil versions of Mark Grayson and brings them to the main Invincible universe, allowing them to wreak havoc on the world. The Invincible War has all kinds of repercussions, including some major deaths, with it being one of the most hyped potential moments in Invincible season 3.

Due to Invincible season 2 giving a heavy focus to Angstrom Levy, it is possible that he could return in season 3. Invincible season 2 ended with Mark believing that he killed Angstrom Levy, putting the final piece in place for Invincible season 3 to contain the Invincible War storyline.
