Kyle
From UnAnything Wiki
Kyle is a weird, cold-blooded Bionicle villain who wants to kill Jaller. However, he is actually Jaller's evil cousin. Kyle used to be normal, apparently, but he did drugs. This turned him into a cold-blooded killer, apparently.
He failed an audition for The Brak Show because the auditioners thought he wasn't chaotic enough. Plus, he ate one of them.
