Inspired by this, here's my attempt to calculate Kane's turns:
- Debuts in 1997 as a heel coming after Undertaker.
- Turned face for a bit in early 1998 to side with 'Taker vs. D-X.
- Turns heel at 1998 Royal Rumble when he betrays and sets Undertaker on fire in a casket.
- Turns face in Oct./Nov. 1998 when Paul Bearer betrays him for Undertaker, then having an alliance with Stone Cold Steve Austin for a bit.
- Turns heel shortly after as a member of The Corporation.
- Around April/May 1999, turns face and teams up with D-X's X-Pac.
- Turned heel in Summer 2000 to feud with American Bad Ass Undertaker.
- Turned back face in early(?) 2001 to team up with Undertaker as the Brothers of Destruction. Would disappear for a bit in 2002, but returned as face with a new appearance.
- Turned heel in August 2003 after being unmasked.
- Turned face in 2005(?).
- Turned heel in 2007(?)
- Stays face until 2010, when he reveals his "plan" to destroy the Undertaker.
- Returns in 2011 with a new, masked appearance.
- Turned face in late 2012 as part of Team Hell No with Daniel Bryan.
- Turned heel in November 2013 when emerging as "Korporate Kane" after going missing for a few months due to being taken by the Wyatt Family. He joins The Authority as "Director of Operations".
