What’s the first thing you think about when you hear the word wonder or super or even bat?
Probably(if you do think of the teen heroes first, then you can skip to the end)not Wonder Girl, Supergirl, Superboy or a younger Batfamily member.
How many teen heroes do you know of?
Famous or not so famous.
I wanna know about them.
Edit: this topic is not limited to the super, wonder & bat families
Teen Titans come to mind… 
Well there’s Slobo, Impulse… Are you asking me to list every single one?
Young Justice has quite a few and that’s when I was introduced to a lot I’d never heard of like Tracy 13, Impulse and Halo.
Sure, if you want to.

My faves teens in those categories are Cassie Cain (bat), ( Wonder Girl Cassandra Sandsmark as a teen in the words u asked for) so that would be Super. Supergirl as a teen of course. Power Girl as Teen (both arrived as teens or were teens during travel and she basically fits under Supergirl category ). Barbara Gordon, would add Wonder Woman if allowed as a teen. Donna Troy too. That might be it for Teens under Bat, Super , or Wonder categories. Nope Stephanie Brown.
Oops . I just saw the disclaimer. I read top & post & it said Wonder, Super or Bat. I’ll keep mine but just teens.
