"Smallville" Super Post!

This post, ironically, isn't as super as the other ones, but that's ok.  Sometimes it takes a while - even for a popular show - for an adaptation to trickle into continuity.  At any rate, Smallville is already on its way to becoming one of the all-time high sources of canon immigration.

In Superman/Batman #44 (February 2008), Superman mentions that Kryptonite can give powers to humans and turns them into a twisted version of themselves. This is a reference to Smallville (2001) - specifically, the plot device that gave him villains to fight every week for the first couple of seasons.
