And some are not Robin villains at all. Harley? Talon?!

The problem with "Robin" is there are plenty of those, and apart from Tim, they had few solo adventures (unless you count the New Carthage days of Dick). The rest of solo adventures is Nightwing, Red Robin or Red Hood. Not Robin. Which is more an argument against a Robin navbox than anything.

Black Lightning could be done. Now name 5 villains and supporting characters that aren't related to him :). Research allowed.

Starman has a similar issue as Robin - many people with the name. But at least he's not using someone else's villains. Between all of them, there's probably enough to fill a navbox.
