Yara looks rad. Hope she's cool and they find a way to incorporate her into the mainline if so. I don't think she needs to be Wonder Girl to become Wonder Woman. Just give her a unique identity and branch the Wonder family out more.

I swear if those aren't mementos from fallen friends Diana is sporting, but instead trophies, I'm out. I'd get this to see Jen Barrel do inheritor art alone but that would be a deal breaker.
