Kefka – Final Fantasy VI
Chances are you were expecting Sephiroth somewhere on this list, right? While true that Sephiroth wasn't quite the full shilling, the infamous Kefka of Final Fantasy VI is a much better representation of the term 'psycho'. With a dark sense of humour and trademark high-pitched cackle, Kefka earned himself the nickname 'Psycho Clown' amongst fans, a name that was reflected in his jester-like appearance. The first test subject as a Magiteck Knight, Kefka was gifted with powerful magic, but it was too much for him and shattered his sanity. Immensely powerful and stark raving bonkers at the same time; a combination that doesn't bode well for the heroes of FFVI...
Harman Smith – Killer 7
If we were in a more boisterous mood, we would have used each of Harman Smith's seven personalities as an individual entry in our top 10, but for the benefit of time, space and indeed our own sanity, we have limited the character(s) to a single entry. In his head, Harman Smith assumes the role of one of seven personas (collectively known as the Smith Syndicate), all of which have unique traits that enable him to carry out his duties as an assassin with alarming success. Garcian Smith, Dan Smith, KAEDE Smith, Kevin Smith, Coyote Smith, Con Smith and MASK de Smith are seven parts of a unique killing machine. Harman Smith is not a person you want to be on the wrong sides of.
