"Knight Time", is one of the best episodes of Superman the Animated Series ever, Superman learns that Batman/Bruce Wayne has gone missing and decides to head straight to Gotham to investigate the disappearance of his sometimes uneasy ally. What he finds is the deadly city overrun with crime as the Dark Knight's rogues are running rampant in the streets with no one, but Robin to stop them. So when the Man of Steel meets up with the Boy Wonder they both decide to put the element of fear back in Gotham City's thugs by having Supes don the 'ol cape and cowl. But no matter how much you dress up Superman in Batman's fear-striking attire, he is still same old Boy Scout underneath, which is why Robin has to give the Kyptonian superhero a crash course in detective work, fear and intimidation.
We get some classic moments as the "Bat of Steel" and the Boy Wonder meet up with Commissioner Gordon and officer Montoya who points out to Gordon that Batman, "looks bigger". We also get to see the "Super-Bat" go up against The Riddler, The Mad Hatter and Bane! And as the all-new Dynamic Duo continue to uncover the secret of Wayne's disappearance, Superman points out to Robin how all this sneaking around isn't really his style to which Robin replies with a smile, "What do you mean? It's half the fun."
