Batman: The Brave & the Bold s3e9 "Powerless"

This episode features the Batmen of All Nations, the Justice League International, Captain Atom doing G.I.Joe-style PSAs that lack only the "...and knowing is half the battle" line (but have an equally silly one in its place), and Aquaman spontaneously breaking into a musical number which he afterwards calls "Aquaman's Rousing Song of Heroism" and in which he appears as a couple dozen different superheroes, from Superman to Dr. Fate to Steel (the Detroit League version) to Black Canary. Yes, Aquaman as Black Canary.

The story ends up being the same as every other Red Tornado story ever, in that it's basically a Pinocchio story about a toy who wants to be a real boy, but I love that this one explicitly acknowledges that fact.

The dynamic immediately established between her and the other characters--especially Robin--is great, so I hope she becomes a frequently recurring character, if not a regular one. Eventually she puts on a standard Zatanna costume, but at first she shows up wearing a sort of Catholic schoolgirl outfit, which totally works for teenage Zatanna:
