Crisis of Infinite Episodes - Bane

Although Bane was still a brand new villain, he got a fairly serviceable introduction here. Sure it wasn't the instant classic like the introductions of Freeze or Two-Face, but Bane's brains as well as brawn were introduced giving the baddie more respect than he would get on screen for years to come. 

Crisis of Infinite Episodes - Harlequinade

 

By this point, Harley had already cemented herself as a star, but her musical solo was the icing on the cake. It was a ton of fun watching Batman team up with the Clowned Queen of Crime just waiting for her to double cross him, because you knew it was coming.

If Ra's last episode was a tribute to classic Bond movies, this episode paid homage to Indiana Jones. Once again, seeing Bats and Talia team up was a lot of fun, even if I never quite understood what the grand plan really was.

Crisis of Infinite Episodes - Sideshow
