This is not a rant and it's not reducing my enjoyment of the series (IT'S FREAKING GOOD) but like the title says I'd like someone to open my eyes on the matter.

1. Ep 1- Throws a baseball across the globe I think casually. Same episode he struggles against the rock guy(Titan)
2. Ep 2- Gets a rage boost after seeing Eve almost die, yet can't kill the alien boss
3. Ep. 5- Stops and throws an asteroid back to space. Rage boost doesn't do shit against the thugs he faces.

I get some things are done for plot reasons, but can someone tell me an estimate of his base strength and whether his powers will keep fluctuating as the show goes on?

This is “Crimson Mark” In his universe, Nolan pieced into marks head the ideals of Viltrum as he grew, although keeping these teachings from Debbie.

Once mark got his powers, Nolan began training him physically right away, it was a grueling effort, but with Nolan’s help, over the course of a year, mark got powerful, for a bit he was a hero, even got his outfit and wanted it to look bold but intimidating. As Invincible, mark grew quickly to feel it was right to kill the villains he fought. After another year mark continued to be a hero although increasing more of a loose canon, especially with the extended time he spent training with Nolan

Once Omni Man killed most of the guardians, Immortal managed to escape,

Afterwards when Nolan recovered, he revealed the whole truth to mark, shortly after, immortal came back and started to fight Omni Man,

Mark, being conflicted, tried to get both of them to stop, but once he realized neither was going to budge an inch, he realized that talking, was pointless, the following battle was brutal, with mark barely making it out the victor of the three.

Knowing that the Viltrumites would be on their way, and also knowing he couldn’t beat them, Mark decided to take over the planet, the once bold Hero, turned into a silent killer, mark had learned that the best way for him to solve a problem, wasn’t to talk it out, or give a speech, but to end it, permanently.

This Version of Mark is stronger than most Variants, and is not to be trifled with.

Compared to where he began in S1. How far has Mark come in terms of his overall power and skill set?

So Let's say that Mark had a pretty similar uprising to MCU Pete, with a few differences.

Firstly, Mark lived with his parents like a normal kid in New York, until a burglar came in and shot Nolan killing him (For Simplicity's sake let's say he had powers when he was younger but somehow lost them).

This leads to Debbie having to raise Mark on her own, and when he hits 17, his powers kick in for the first time and she explains his Viltrumite origins to him, Mark then sets out to become a great hero and prevent others from sharing his fate.

What Would happen with Mark replacing Peter? could he get as far as Pete did? How would the Avengers act with him around?

Invincible is by far one of my favorite comic books I’ve ever read and a huge part of that is the fact that it’s a complete story from beginning to end with no need to commit to some status quo. The characters are allowed to grow up and permanently change, characters stay dead, etc. That being said, I have a few gripes with the way Mark’s characterization was handled towards the end of the series.

One of the best parts of Mark’s character arc was his internal conflict over whether or not he should kill. The way this was handled felt so refreshing from other comics bc we got to see Mark actually try and start killing people as opposed to abiding by some strict code. And after the fiasco with Rus Livingston, Mark realizes that killing is too easy and goes back to trying to be a hero without doing so. We got to see our hero go through actual change by starting to kill people and then ultimately realize why it’s wrong. It was major growth in his character.

Except suddenly Mark goes back to killing villains because….reasons. Like after that entire conflict over whether he should kill or not, Mark kills Conquest and it’s casually written off as “oh it’s war so it’s necessary”. I mean sure I guess I can get on board with that, except then Mark goes back to Earth and tries to kill Dinosaurus after the global catastrophe. And when Dinosaurus redeems himself, Mark kills him instead of finding another solution (not to mention he killed Dinosaurus’s innocent host). This is straight up just never addressed. I’m fine with mark going back to killing if it’s done in a way that makes sense and remains consistent with what’s previously established but the way it’s written makes it seem like all the stuff with Rus Livingston meant nothing and was just completely undone.

Then Mark proceeds to do even worse shit like saying “being a hero is bullshit” and kills Thragg’s kid in cold blood. Ok fine, Mark’s not a hero anymore he’s just some guy trying to protect his family, but then right after that he joins the war effort against Thragg and claims he doesn’t wan’t too see Thragg killing any more of his own children (real ironic considering he killed one of them) and knocks him straight into the sun, makes a big speech about how he’s fighting for all his people including thragg’s own army, and how the vilturmites can spread peace throughout the universe, and sacrifices his own life to stop thragg. This sudden return to heroism comes completely out of nowhere after the previous issues focus on mark making the selfish choice to prioritize his family over being a hero and even leaving earth so he wouldn’t have to fight Rex. Except all of a sudden right after beating thragg mark goes back to earth to fight Rex and claims that he was wrong to have left earth in the first place, which feels like a total 180.

All in all Mark’s characterization seems to randomly flip flop with no explanation towards the end of the series. One moment he’s a moral, compassionate hero and the next he’s a gray anti-hero then he’s just a guy trying to protect his family then back again. Like what’s the takeaway supposed to be here? Is Mark actually a hero? Was his entire character arc about realizing he’s not actually a hero and giving up on trying to be one? Does he try to return to being one by the end? It just ended up leaving me confused which is a shame because he was a genuinely well developed character for the majority of the series.

Scenario: Wanting to redeem himself after his fight with Omni-Man(his father), Mark Grayson a.k.a Invincible has moved into New York City where Peter Parker has moved out, leaving Mark to become New York's protector and having to deal with all of the trials and tribulations that Peter has dealt with, including his rouge gallery.

Invincible's rouge gallery: Venom, Colonel Jupiter, Green Goblin, Vulture, Shocker and The Enforcers, Sandman, Electro, Sandman, Rhino, Tombstone, Hammerhead, Silvermane, Chameleon, Kraven The Hunter, Doctor Octopus, Molten Man, Mysterio, The Lizard and Silver Sable.

Mark also has to contend with J. Jonah Jameson and The Daily Bugle's views on him and masked vigilantes in general.

He starts at the beginning of the series and he's in character(as of the end of Season 1 of Invincible, Mark has gained basic knowledge of New York City and the villains are aware of Mark Grayson's identity).

Can Mark Grayson become Peter Parker's successor?

Debbie Grayson is one of the strongest characters in Invincible, and not because she can throw a punch. She’s the only one who can stand up to Mark without fighting him.

This scene is so powerful because she’s not just arguing—she’s calling him out. Mark grew up with Omni-Man’s idea of strength, but Debbie’s the one who’s teaching him what real strength looks like. Not power, not dominance—just doing the right thing, even when no one can stop you from doing the wrong one.

She knows she can’t make him listen. But she still tries. And that’s why Mark is becoming the right kind of hero.

How much of Mark’s heroism do you think comes from Debbie?

I know what everyone will think reading the title, but the fact is Invincible doesn't really have "superpowers" all of his powers are 100% natural to his species like our ability to run, jump and spit(a lot of animals can't spit) are for us humans.

What if he was granted super powers through science, magical or other unknown means? Imagine if he had the same ability as Dupli-Kate?

I guess the point of this is, would this make a good "what-if?" story or is it interesting to you as a reader/watcher of the series the idea of Mark gaining powers other than his natural abilties? I guess another reason I'm making this, I just never saw anyone discuss this before.
