This article contains plot/ending details.
Cole is a drummer who joined Kid Chameleon at Envy's request, forcing Scott Pilgrim to switch to bass. Presumably he was a much better drummer than Scott. He has black hair, dark-framed rectangular glasses and sideburns.
He appears in flashbacks in Book 3, and then later in Book 6 as the drummer for Stephen Stills and Joseph's Unnamed Band. Also, somewhere in between Scott Pilgrim vs. the Universe and Scott Pilgrim's Finest Hour, Scott encountered him and stabbed him in the face with a fork, assuming he was Gideon.
