We've got another Teen Titans short from The Superman-Aquaman Hour of Adventure, "The Space Beast Round-Up". Scope it!
To think it took some 35 years before the Titans would return to TV, albeit based on the 1980's incarnation, but done in Americanized anime. If it wasn't for the anti-violence movement that started the following year, there was perhaps the chance these Titans would've been spun off into their own series, with Robin joining them by that point. Ah, what was and what might've been.
