Summary
- Invincible’s power scaling impresses with strong main characters.
- Unique weak characters like Elephant provide diversity in the series.
- Street-level threats like Killcannon and Machine Head add depth to the superhero world.
Invincible has gained immense popularity on Amazon Prime as one of the top-rated animated superhero shows, and it’s not hard to see why. This outstanding series takes inspiration from some of the best DC and Marvel animated superhero series, like Justice League and X-Men Evolution. One of the key features of the show is its power scaling, as the main characters display remarkable strength and distinctive abilities. However, no superhero series can do without its own filler characters and common threats.
In the world of Invincible, an array of superpowered characters with varying strengths are present. Some are humorous or pay tribute to characters from different dimensions, but many possess intriguing roles. Even the weakest characters in this universe hold distinctive personalities that make them memorable, and they aren’t simply overlooked or considered insignificant.
8. Elephant
A Man With the Strength of an Elephant

The Elephant serves as a somewhat humorous antagonist with occasional appearances. He isn’t strictly villainous but takes on small jobs as a hired gun. Despite having kind intentions, his immense power can potentially be harmful to ordinary humans. His primary goal is to discourage people from consuming meat, which he does by displaying his strength and asserting that he gained it due to his vegetarian diet.
Essentially, he’s a character portrayed as an elephant in a suit, featuring a trunk and oversized ears, and boasting strength comparable to the actual animal, capable of lifting roughly 6 tons. However, compared to the characters in the Invincible universe who can demolish cities, level mountains, and obliterate asteroids, his power seems rather insignificant. Due to his peaceful demeanor, this character, known as Elephant, serves as a training tool for Invincible and, at a later stage in the series, his sibling Oliver.
7. Killcannon
Atom Eve’s Arch Nemesis is Quite Weak

In the series, Killcannon becomes the initial villain to be conquered by both Invincible and Atom Eve for the first time. He debuts in the inaugural episode following Mark’s acquisition of his powers, as he searches for suitable ways to employ them within the city. As Killcannon flees a bank robbery, he crosses paths with an inexperienced Invincible. Their encounter results in a feeble resistance from Killcannon, making it simple for Invincible to subdue him. Similarly, during his battle against a young and green Atom Eve in the comic “Invincible: Atom Eve“, he succumbs swiftly to her novice abilities.
Compared to an elephant, his physical strength might actually be quite feeble. However, it’s his arm cannon that makes him a significant danger due to its destructive capabilities. In their second confrontation, this weapon demonstrated a strong performance against Atom Eve, thanks to the supercharging by Robot’s device. Known as Killcannon, he is more sinister and doesn’t hesitate to endanger innocent lives. Nonetheless, he’s generally quite weak in terms of overall power.
6. Isotope
Right-Hand Man to Street Level Crime Syndicate Bosses

In the series, Isotope is undeniably the least powerful super-character, yet he manages to make an impression due to his unique power that can be manipulated. He often serves as a trusted associate or second-in-command to the underpowered crime syndicate leaders. Initially, he was employed by Machine Head, but later turns on him and joins forces with Titan, who seizes control of the criminal organization. Later, Isotope reteams with Machine Head, who escapes from prison as a result of Mr. Lee’s rampage.
As a devoted admirer, let me share my thoughts on Isotope: His unique ability lies in teleportation, yet the rest of him is remarkably human, giving him limited strength. Despite this, he’s a cunning character who skillfully navigates challenges, always mindful of his limitations. In critical moments, when utilized shrewdly, his powers prove incredibly beneficial for extricating himself from perilous situations.
5. Machine Head
A Gimmicky Crime Boss With an Autotuned Voice

In the gripping world of “Invincible,” Machine Head quickly captured the hearts of fans in season one, not because of his brute strength or supernatural abilities, but rather due to his intricate connections within the criminal underworld and his skillful navigation amidst a sea of superheroes. To put it simply, he’s the kind of guy who can manipulate even an intimidating figure like Battle Beast into engaging in a street-level brawl – now that’s impressive!
Machine Head possesses strengths rooted in his intellect and the capacity to enhance it, as his head symbolizes a mechanical entity. Upon receiving a chip from Titan, Machine Head integrates this technology into his own brain, which appears to grant him abilities of prescience. These skills enable him to predict Titan’s treachery, leading him to recruit several superpowered individuals for the purpose of confronting Invincible and Titan.
4. Titan
Impressive Strength & Durability

Among the engaging antagonists operating at the grassroots level, Titan stands out. Initially presented as a henchman for Machine Head due to a personal obligation, he later deceives Invincible into collaborating with him to bring down Machine Head, allowing him to seize power. He uses the appalling living conditions on the streets, which are a result of Machine Head’s oppressive rule, to create a moral quandary for Invincible.
In the course of the series, he consistently displays remarkable feats of power and resilience that are reminiscent of a blend between Tombstone and Luke Cage from the Marvel Comics world. His abilities enable him to transform his body into a rock-like structure that is nearly indestructible by bullets, and he experiences significantly less pain when struck. Additionally, he demonstrates proficiency in hand-to-hand combat. One of the most astonishing moments in the series was when he withstood several attacks from Battle Beast, one of the strongest characters known to us, with minimal injury.
3. Doc Seismic
The Genius Environmentalist Plagued by Poor Mental Health

Doc Seismic frequently serves as a secondary antagonist in stories, possessing street-level abilities, yet he consistently showcases an impressive skill set that often necessitates the combined efforts of powerful superheroes to bring him down. While he’s not typically regarded with much seriousness, his capabilities suggest otherwise. The character is a topic of discussion among fans of Invincible, as there is debate about his true intentions. He harbors a belief that humanity’s arrogance is leading to the planet’s destruction, and his ambition is to instate a new global order that prioritizes nature above all else.
His abilities appear to match those of powerful mutants seen in the X-Men series. He’s capable of inducing seismic shockwaves that can lead to destructive earthquakes and devising clever strategies. However, his mental instability makes him volatile and unpredictable, posing a threat even to superheroes like Invincible. Despite this, he proves to be a formidable adversary, often requiring multiple superheroes to counter his schemes. In the grand scheme of things, the series portrays him as a common street-level antagonist.
2. Donald Ferguson
Cecil’s Loyal Right-Hand Man is a Capable but Weak Cyborg

Throughout much of the first season of Invincible, it seems like Donald is just a normal human working for Cecil. He’s one of Cecil’s most faithful enforcers, serving as his second-in-command at the GDA. However, as the series progresses, we discover that he’s actually a cyborg, with only his brain remaining as his original human component. Similar to the Immortal, Donald has experienced death on multiple occasions and each time, his cybernetic body is rebuilt.
His strength and durability significantly exceed those of ordinary humans, allowing him to endure incidents that would typically annihilate numerous super-powered individuals. For example, he survives having his spine crushed by Omni-Man in Season 1. This extraordinary resilience to death has given Donald a somewhat reckless attitude, encouraging him to confront dangers far beyond his capabilities. Additionally, he is exceptionally intelligent, often demonstrating a higher intellect than Cecil, and possesses a keen intuition.
1. Brit
Invulnerable to Damage, But Has Little Else Going For Him

In the third season, Brit makes his appearance, hinting at a distinguished past with Cecil Stedman. Previously serving as a soldier, he acquired an extraordinary ability – absolute resistance to any form of harm. This unique backstory creates an intriguing character dynamic, as despite this seemingly unbeatable trait, Brit is among the series’ least complex characters. Apart from his invincibility, he doesn’t have many other distinct characteristics.
Brit possesses remarkable fighting skills, given that he was trained as a soldier in battlefields. Additionally, he exhibits an exceptional level of strength, capable of lifting weights well beyond what normal humans can manage. However, it’s uncertain if his strength is naturally enhanced or if his resilience allows him to perform tasks that would typically be too strenuous. A captivating hypothetical situation would involve pitting him against the strongest character in the series, either Thragg or Invincible, to test the limits of his invulnerability. Nevertheless, he’s not demonstrated much due to his ability to withstand any harm that comes his way.
