I'm surprised it took more than 3 years for me to return to this topic, but alas, I wanted to do this again. Feel free to discuss the merits of each assessment at the end. Once again, I'll only be focusing on the main villain or antagonist(s) of each project.
Scarlet Witch (Doctor Strange in the Multiverse of Madness)
Whereas Strange has a more sacrificial approach to life, having accepted he won't marry Christine and putting his life and others at risk during the Blip, Wanda's constant losses have drawn her to be more proactive in her search for her own goals, even if they tend to be on the more selfish side.
Green Goblin (Spider-Man: No Way Home)
Speaking of selfish, the Goblin's god complex and disregard for innocent lives is the complete anthesis to Peter. While at various points Spider-Man does wish to neglect help to the villains, he is ultimately morally obliged to help, even more so than his variants
Namor (Black Panther: Wakanda Forever)
While the first movie pitted the King against against "common man", movie two makes this a War of Kings, or more closely, a war of Heirs. Namor reflect not just Shuri's desire for vengeance against an unfair reality, but is a shadow of T'Challa.
While T'Challa was very much a man of his people, even talking a stroll with them, Namor is deified. He is alone even among his own people. And his status as the orphaned child seeking revenge is all too similar to Killmonger.
Kang (Ant-Man and the Wasp: Quantumania)
In a way, Kang has the stature Scott wishes he had. In the Quantum Realm, Kang is feared by some, respected by others. He has power and is taken seriously. And nobody mistakes him for anyone else.
Taskmaster/Dreykov (Black Widow)
I'm putting these two together since one works as the physical threat and the other as the psychological one. But in the literal sense is the past coming back to haunt Nat.
Antonia's condition is Nat's worst case scenario, i.e. no autonomy. Dreykov's is the sense that she did nothing to change the system that forged her that day.
Gorr (Thor: Love and Thunder)
While not as serious as his comicbook counterpart, Gorr's mind snapped with the death of his child + learning the truth about his god. In that way, Gorr is a departure from the mythical villains of past films being the believer turned antitheist. And Gorr is the manifestation of Thor's insecurities, and his disappointment in the rest of the gods for not helping the world.
Anyone I've missed in these two that you'd want me to do next? Leave them below. Link for my previous analysis is also here, if you're interested in reading them.
