The Marvel Cinematic Universe has progressed so far that some avid fans can't even keep track of all the characters anymore. However, some characters stood out, so much so that having their own movies might even be a hit if they were produced.
1. Valkyrie/Brunnhilde
From being apathetic towards Thor's problems to becoming a warrior on the God of Thunder's side during Ragnarok, we quickly see just how formidable she can be. After Loki got into her head, we also witnessed the tragedy that led to her being the last Valkyrie. It would definitely be interesting to see what it was like when the elite force of shield-maidens was still around.
2. Mantis
If we got to see the human celestial hybrid Star-Lord with his adventures, it might be cool to also watch his half-sister's life in her servitude to Ego. All we know is that she was raised by the psychotic celestial, but all the things she went through during that time are unknown. Either that or the movie will follow her adventures after "Guardians of the Galaxy Vol 3."
3. Okoye
Loyal to Wakanda and those who aim to protect the land, Okoye is the kind of warrior that you want by your side. The good news is that a "Wakanda" series in development already has the actress behind the character Danai Gurira, involved. It would be nice if it showed the origins of Okoye and how she came to be the general of the Dora Milaje.
4. Wong
Even though Wong is seen as a serious character, he still manages to make fans laugh in certain scenes where he is involved. He has been in Kamar-Taj long before Dr. Strange found it, so one can only imagine what he has been doing in the past, which would also explain how he learned everything he knows now.
5. Hank Pym
It was already explained in the "Ant-Man" movies how Hank discovering the Pym Particles led to the tragic loss of his wife, Janet van Dyne as she sacrificed herself. While her story led to her being back on Earth, seeing Hank and Janet as Ant-Man and the Wasp would make for a cool prequel, especially since they served as the original wearers of the suits.
6. Yondu
Despite being tough, Yondu is a beloved character in the MCU after "Guardians of the Galaxy Vol. 2" showed how he actually cared for Peter Quill like a son. It was also revealed that he was exiled from the original Ravager group because they weren't supposed to "deal in kids." A movie about his friendship with Stakar before his dealings with Ego would be a good story.
7. Morgan Stark
In "Avengers: End Game," we finally see Tony Stark have the family he deserves especially with his interactions with his daughter Morgan. While we saw very little of her, the statement "I love you 3000" stuck with us. Being the daughter of a memorable character, it would be exciting to see what she does when she grows up, perhaps continuing the Stark legacy of innovators.
