Korvac is considered to be one of the greatest galactic threats in Marvel Comics. Point blank, there are maybe 4 people considered stronger than him and they are either Gods or the literal writers themselves. In the alternative Earth-691, Michael Korvac betrays humanity to the Badoon alien race in 3007 AD. Yet he is eventually caught asleep while working and as punishment, the Badoon grafts his upper body into a machine. That turns him into a cyborg with updated alien technology inside of him. The Grandmaster and Elder of the Universe send him back in time to fight the Defenders and Dr. Strange.
Korvac lost this fight but did so on purpose. He used this time to scan the Grandmaster’s cosmic power, allowing him to gain several cosmic abilities. With this newfound power, he kills the Badoon leaders. While he decides to conquer the cosmos and attempts to make the Earth’s sun go supernova to distract the world’s heroes, he is stopped. Yet a run-in with Galactus allows him to gain the “power cosmic.” Korvac is then a God and consistently gets into some incredible incidents. He’s set to appear in Captain Marvel 2 as the big bad. He’ll surely be one of the Marvel Comics characters that people will love instantly.
Mephisto is best described by calling him Marvel’s version of the Devil. Seriously, that is basically what this character happens to be. While he has been a cosmic threat, he often stands out as a magical being that affects several layers of the universe as well. He was initially introduced as a big bad for the Silver Surfer and Johnny Blaze (Ghost Rider). Yet he’d go on to have altercations with the likes of Dr. Strange and most notably, Spider-Man.
Due to having his fingers in so many different areas of the universe, he has become a major figure in the universe. Thus, he’s one of the Marvel Comics characters everyone expected to see in the MCU by now. While he has appeared in Ghost Rider movies, those are not MCU canon. Yet Mephisto is expected to be introduced into the MCU very soon, likely by the upcoming Dr. Strange film. When he pops up, he’ll likely be around for quite a long time. Get used to him everyone. The Devil is here.
First Appearance: The Amazing Spider-Man #31 (December 1965)
Created By:Stan Lee & Steve Ditko
Gwen Stacy was initially introduced as an early love interest for Peter Parker. Yet writers wanted to have Peter not only grow up more but look vulnerable. There isn’t a better way to do this than to hit them with something heartbreaking. The Green Goblin causes Gwen to fall from a great height, only to be caught by Peter. Yet the webbing caught her badly and she died. While she is dead in the mainline Marvel universe, the introduction of the multiverse gave her the opportunity to return. Marvel writers felt, given her consistent popularity, they could use her more in the multiverse.
That led to two characters being formed for her: Spider-Gwen and Gwenpool. Though the latter was fun, it was short-lived. Spider-Gwen became fun to read and the comic success led to Marvel taking it more seriously. Gwen needed to be seen as something more, resulting in her new “Ghost Spider” codename. Now, she is a huge part of the Spider-Verse. We will be seeing a lot from Gwen in the MCU but Marvel and Disney have already included her in many animated projects. Ghost Spider could even appear in the upcoming Spider-Man: No Way Home movie too!
