From season 2 of Batman: The Brave & the Bold:
Batman (Diedrich Bader) first teams with Detective Chimp in the teaser segment, but after that, the Justice Society & Black Canary join the Caped Crusader to take down old foe Per Degaton in "The Golden Age of Justice".
One quibble. In the comics, Professor Zee, shown as Degaton's servant, was actually Degaton's employer, and looked nothing like the character shown here. Instead, the animated Zee bears some resemblance to Dr. Thaddeus Bodog Sivana, arch-nemesis of Captain Marvel. How the producers screwed this up, I'll never know.
For now, we only have this sample:
It's a pity the series has ceased production, but that was Cartoon Network's call. Of course, those idiots are creating some havoc with their DC Nation block, which we'll discuss another time.
