The Lost Episode from The Adventures of Batman and Robin
The Adventures of Batman and Robin is probably one of the best representations of the caped crusader’s adventures in cartoons (second only to the original Robin-less Batman: The Animated Series!), so its episodes have been watched and universally loved by legions of Bat-fans, but unless you have a Sega Genesis with the Sega CD Add-On and a copy of the TABR game, you probably missed out on “The Lost Episode”.
The Lost Episode is basically a series of 16 minute, fully animated cutscenes found in the Sega CD game for The Adventures of Batman and Robin, which can be aranged to form a semi-cohesive story. The limitations of the 16 bit Genesis console and its Sega CD Add on meant that the videos were limited to a 256 color pallete, but the animation was done by TMS, and uses the original voice actors so it stands well on its own as a canonical episode from The Adventures of Batman and Robin TV series.
