The series has received acclaim from critics, with praise for its animation, action sequences, story, voice performances (particularly Yeun, Oh and Simmons), and emotional weight.

[3] Shortly after his 17th birthday, Mark begins to develop powers of his own and learns how to wield them with help from his father, who turns out to not be as heroic as he thought, as he hides a dark secret, which starts to slip when he brutally murders the members of the world's greatest superhero team, the Guardians of the Globe.

The duo were set to produce the film alongside James Weaver through their company Point Grey Pictures, while Invincible co-creator Robert Kirkman also joined to produce alongside David Alpert, Bryan Furst, and Sean Furst through his company Skybound Entertainment, which had a first-look deal with Universal for the film.

[38][39][40] In April 2023, series creator Robert Kirkman stated that the second season would focus on Angstrom Levy, a supervillain with access to multiple dimensions.

[46][47][48] Sandra Oh, Mark Hamill, Seth Rogen, Gillian Jacobs, Andrew Rannells, Zazie Beetz, Walton Goggins, Jason Mantzoukas, Mae Whitman, Chris Diamantopoulos, Malese Jow, Kevin Michael Richardson, Grey Griffin and Max Burkholder also joined the cast of the series.

[52][53] The character of William, Mark's best friend, is openly gay from the outset of the series in contrast to the comics, where he spends a significant amount of time closeted.

Invincible's creator Robert Kirkman revealed that he wanted to represent the dark days that lie ahead by using the increasingly bloody title cards.

[70] On January 20, 2023, a teaser trailer was released, in which Steven Yeun and Seth Rogen as Invincible and Allen the Alien respectively discuss the upcoming season.

The site's consensus reads: "With bold animation, bloody action, and an all-star cast led by the charming Steven Yeun, Invincible smartly adapts its source material without sacrificing its nuanced perspective on the price of superpowers.

The site's consensus reads: "Still as bracing as a punch to the face and invigorating with its vivid worldbuilding, Invincible is practically impervious to disappointing audiences in this sterling sophomore season.

"[89] Caroline Framke from Variety commented: "Now, of course, Kirkman is the wildly successful co-creator and executive producer of 'The Walking Dead,' so even those who might not have picked up an 'Invincible' comic might be interested in this spry, hourlong animated series that somehow manages to be both snarky and earnest within the same breath.

"[91] Bob Strauss from Datebook praised the show, commenting: "While you can't describe 'Invincible' as gritty, it does feel like the right kind of animated super-show for an era marked by Zack Snyder's dark-hued 'Justice League' reconstruction and Amazon's own, ultra-pathological take on the genre, 'The Boys.'

"[93] Alan Sepinwall from Rolling Stone stated: "As the series moves along, Kirkman and company begin introducing twists to what we think is the formula — perhaps too many.

"[94] Roxana Hadadi from RogerEbert.com praised the series for its story and animation, commenting: "'Invincible' sets up those questions quickly and engagingly in these first three installments, wraps them in a mystery, and then splatters them with blood.

"[96] Louis Chilton from The Independent gave the series 3 stars of 5 and stated "Invincible often seems derivative; perhaps its ideas were more groundbreaking in the original early-2000s comics.

Some of its characters are unapologetic parodies (the Batman facsimile "Darkwing", for example), and you could easily go through picking out elements or story ideas that have cropped up in Watchmen, or The Incredibles, or Sky High, or Misfits.

[43] Invincible creator Robert Kirkman was sued by comic book colorist William Crabtree, citing a rights and profits concern, on January 10, 2022.
