11. Spider-Man
While Robert Kirkman was writing Invincible, he was penning Marvel Team-Up. He had the genius idea to bring Mark into the Marvel universe in Marvel Team-Up No. 14. Within that crossover, Mark Grayson beat Doctor Octopus with ease and met the Avengers. Not shocking to anyone, Mark was weird around them. He gave them all nicknames based on Peter calling himself Spider-Man. Among them were Claw-Man (Wolverine) and Fabio-Man (Sentry)
This may be a long shot, but it’s possible. If you don’t see him, there’s a possibility that his webs will come through Angstrom Levy’s portals. It happened in the Invincible comics. Why not on Amazon Prime?

10. Tek Jacket
Tek Jacket isn’t a character that’s going to woo anyone with super strength or invulnerability. Instead, you’ll be amazed by the creative things his armor can do. The easiest way to picture it is if you combined Iron Man and Blue Beetles armor.
At first glance, it looks like something Iron Man would have built in his earlier days. Similar to Blue Beetle, the suit is alive. Also like Jaime Reyes, Tek Jacket is goofy at times but has the ability to stand up against and defeat a Viltrumite.

9. Conquest
Invincible will be overwhelmed by a lot of villains throughout this series. None of them as much as Conquest. Not even the biggest and most terrifying of the Viltrumites (Thragg) achieved what Conquest did. He didn’t just brutally batter Mark. Conquest almost killed him and psychologically tortured him. If that wasn’t enough, Conquest murdered Atom Eve in front of him and taunted after it.
Trust this writer when he says you’ll never forget Conquest. He’s easily one of Invincible’s greatest enemies.
