9. Ms. Marvel

Kamala Khan is maybe the best and most beloved addition to the Marvel Universe of the 2010s.

She's fun and entertaining and totally lovable. If you aren't currently reading Ms. Marvel, you’re missing out. That thing is the bomb-dot-com. But if the MCU is going to survive into the future, it needs to keep introducing characters who don't age out of the parts within five years of getting them. So a revolution of teenaged heroes is about due.

We already have Spider-Man; maybe we should throw Ms. Marvel in there, as well. Kamala Khan is an inhuman with body-warping abilities. She can stretch a tiny bit, grow, and shrink. She can also individually alter the size of her own limbs. She patrols the streets of New Jersey, which puts her a bit outside of the Avengers’ regular stomping grounds.

Having a street-level hero on the squad is a good idea, as is getting another teen to play off Spider-Man. And Kamala's a good pick for both roles.
