9. Cassie Lang

Cassie is so great. I really hope the movies let her age into adulthood so she can take on her comic book identities.

Cassie had a heart condition, which inspired Scott to steal the Ant-Man outfit so he could save her. The teenage Cassie lost her father during Avengers: Disassembled, and she started messing around with Pym Particles. She met up with the Young Avengers, started dating the teenage Vision, and used her new size-changing powers as Stature. A pretty good name for a new Ant-Hero.

She used that identity off and on for a long time. But after more dealings with her revived father (and she died and came back as herself) she took on a new name: Stinger.

Of course, she’d already been going by Stinger in the MC2 Marvel alternate future. Because comics are confusing.
