0 0

Warning: Contains SPOILERS for Invincible season 3!

Invincible season 3 has come to a close, and here are the top 10 strongest characters who have been introduced in the Amazon Prime Video show so far. The world of Invincible is full of incredibly powerful characters, with the Viltrumites only scratching the surface of the power potential that the show's heroes and villains have. Even more incredibly powerful characters were introduced in Invincible season 3, so here is a full breakdown of the show's strongest characters so far.

Fans of Invincible who have read the comics may know about the future of the story, with even more powerful characters just waiting to be introduced in the show. However, since characters like Grand Regent Thragg haven't been introduced in Amazon Prime Video's Invincible yet, these Titans aren't in the running for this list. This list will only consider characters who have been seen in Invincible's first three seasons, and it will be going based on their power level and abilities as of the Invincible season 3 finale. So, here are the 10 strongest Invincible characters from weakest to strongest.

10 Space Racer

Introduced In Season 2

Although he has only had a brief appearance in Invincible so far, Space Racer is already one of the show's strongest characters. Space Racer has only appeared in a flashback in Invincible season 2, with Mark and Allen the Alien discovering who he is through one of Nolan's books. Space Racer is one of the few characters capable of killing a Viltrumite in the Invincible universe, although it isn't due to his powers.

Instead, Space Racer is able to weld the most powerful weapon in the Invincible universe: the Infinity Ray. The Infinity Ray is able to shoot indestructible blasts that will tear through anything in the universe. This includes Viltrumites, meaning that Space Racer is capable of killing them in a single blow. However, Space Racer is the only one who can fire the Infinity Ray, making him an incredibly valuable character.

9 Kregg

Introduced In Season 1

Kregg is a character who hasn't been seen since Invincible season 2, with him being the Viltrumite who tells Mark that he has been appointed to prepare Earth for Viltrumite invasion. Kregg's fighting potential hasn't yet been seen in the show, although his Viltrumite heritage instantly makes him one of the universe's most powerful characters. While viewers have only started to see his potential, Kregg is capable of so much more.

In the Viltrum Empire, Kregg is the right-hand man of Grand Regent Thragg, the leader of the Viltrum Empire. This speaks to Kregg's strength, although he is usually sent out as a mouthpiece for the Empire rather than a soldier. Because of this, it can be assumed that he isn't as strong as some of Invincible's other Viltrumite antagonists.

8 Anissa

Introduced In Season 2

Another incredibly powerful Viltrumite who was last seen in Invincible season 2 is Anissa. Anissa came to Earth in order to check on Mark Grayson's progress, with her being disappointed at how Mark's preparations are coming along. This led to Mark and Anissa fighting, although it wasn't as intense as some of Mark's other battles with Viltrumites.

Based on Anissa's own admission, she isn't the strongest member of the Viltrum Empire. Before Anissa leaves Earth, she warns Mark of Conquest's arrival, signaling that he is one of the most powerful Viltrumites. Anissa being sent at all means that she is probably one of the more powerful Viltrumites. However, she is not as big of a threat as some of the other entries on this list.

7 Atom Eve

Introduced In Season 1

Atom Eve has gotten some major upgrades in Invincible season 3, causing her to immediately shoot up the show's power rankings. Firstly, the Invincible season 3 finale shows that Atom Eve can hold her own against Conquest, one of the most powerful Viltrumites. Although he does eventually defeat her, she outwits him for a while, with her surviving for much longer than many others would. The same can be said for her fight with an evil Invincible during the Invincible War, although she eventually lost this battle as well.

Atom Eve's energy blast that she uses on Conquest is a major new power, with her being able to turn the tide in Mark's favor. On top of that, Atom Eve has now learned that she can remove the mental block that prevents her from altering biological matter. Once Atom Eve figures out how to properly use this power, she has the potential to be Invincible's most powerful character.

6 Thaedus

Introduced In Season 2

Thaedus started Invincible out as the leader of the Coalition of Planets. However, perceptions of his power level changed with Allen the Alien made a major discovery about Thaedus: he is a Viltrumite. Thaedus abandoned the Viltrum Empire long ago, with him working with the Coalition to take down his home planet.

Thaedus' Viltrumite powers make him a strong enough character, and more of these abilities will be seen in Invincible season 4's Viltrumite War arc. However, Thaedus is also incredibly intelligent. Thaedus has spent years studying Viltrumite weaknesses, and is even able to synthesize another version of the Scourge Virus. Thaedus' political positions also add to his power, with him having the entire Coalition behind him.

5 Nolan Grayson

Introduced In Season 1

In Invincible season 1, Nolan Grayson was undoubtedly the most powerful character in the show. Omni-Man's battle with his son showed that Invincible stood no chance against him, and neither did any other force on Earth. Nolan is respected throughout the Viltrum Empire for his strength, and he has managed to kill several Viltrumites throughout Invincible's three seasons.

However, Nolan has been outclassed by some other characters as Invincible has gone on. Characters like Allen the Alien and Battle Beast could probably beat Nolan, and by Cecil's own admission, Nolan couldn't beat Conquest. Since Mark does beat Conquest, this also means that Nolan is weaker than him.

4 Mark Grayson

Introduced In Season 1

Mark Grayson is the protagonist and title character of Invincible, and despite his name and prominence throughout the show, he isn't even in the top three strongest characters. Mark Grayson is constantly getting beat up, although he has improved alot throughout the three seasons. Mark's GDA training gave him a major step up in Invincible season 3, and his fight with Conquest proved that he was stronger than his father.

However, it is doubtful that Mark could beat Allen the Alien or Battle Beast, both of whom have beaten him before. While Mark did beat Conquest, he nearly died, and he was only given a second chance thanks to Atom Eve's intervention. Thus, Mark is strong, but he isn't the show's strongest character.

3 Battle Beast

Introduced In Season 1

Although he isn't a Viltrumite, Battle Beast is stronger than many of the Viltrumites in Invincible. Battle Beast was introduced in Invincible season 1, although his true strength wasn't demonstrated until season 3. Battle Beast managed to go one-on-one with a Viltrumite during Allen and Nolan's prison break, and he came out virtually unscathed. The same can't be said for the Viltrumite, meaning that Battle Beast could probably take on even the strongest members of the Viltrum Empire.

2 Conquest

Introduced In Season 3

Of all the Viltrumites who have been introduced in the Invincible show as of season 3, Conquest is the strongest. Cecil explicitly says that Nolan couldn't beat Conquest, showing how powerful he is. While Conquest is defeated by Mark, this is only because Mark had the help of Atom Eve. On top of that, Conquest's metal arm means that he wasn't even at his full power. Conquest is a force to be reckoned with, and the destruction he caused in the Invincible season 3 finale proves this.

1 Allen The Alien

Introduced In Season 3

Allen the Alien got a major upgrade in Invincible season 2, with the Coalition of Planets making him stronger than the Viltrumites. There is nobody in the Invincible universe that Allen can't handle, with him even having to fake being knocked out by Viltrumites in season 2 and season 3. Allen is able to joke around while fighting Viltrumites, and after seeing what they can do to other Invincible characters, this is a true testament to his strength.
