Harley & Ivy
This is why I love them!
Harley is an abuse survivor of course she’d wreck this dude!!!
Can I just say how much I love the implications here?
Harley and Ivy are known public figures. People know who they are, and recognize them. And this kid knows that, despite being violent criminals, they’re safe enough to go to for protection.
Ivy is dead certain that the Batfamily will be okay with them intervening to protect a kid. That has some intersting implications - either she knows damn well where the lines lie and that this is overriding enough to get her a pass, or (more likely, given the first bit) this has come up before.
one of my favorite tropes is villains acting heroically not because the other villain is a threat to them or because it benefits them, but because they have standards
yeah, the trope is called “even evil has standards”
side note, the constant standard shared across all the batman villains is that none of them are, nor will they ever tolerate nazis. as soon as joker found out some people he was working with was a nazi, he turned on them.
