What character/characters would you have wanted to be kept alive to get more character development with?

Essentially what characters did you see potential in that were killed off too soon in the MCU?

Skurge
First off Karl Urban is always fantastic and I'm disappointed he didn't get more to do with the character to be honest. I know quite a few fans are calling GotG Vol.3 the Asgardians of the Galaxy with Thor joining the team, but he's only one Asgardian. Plus in the comics, Skurge is a part of that team.

Quicksilver
I just think he shouldn't have died in the first place to be honest. Especially the way he did. I would've enjoyed seeing more of his sibling relationship with his sister as the franchise kept growing. Not only that, but I like Aaron Taylor-Johnson.

Ronan
Based on what he said at the end of Captain Marvel, I think he could come back in her sequel if it takes place before he fights the Guardians in their first film. That being said I felt he had a lot of potential to be a great villain, but GotG already had to focus on five main characters so I get it.

The Black Order
Mostly Ebony Maw. I thought he was pretty menacing even if he was just a Thanos goon and I honestly would've liked to see more about them as a whole and their whereabouts throughout the time Thanos was sending people to get the Infinity Stones for him. It would've been interesting to see if they'd try to take revenge for Thanos death.
