There isn't a more gargantuan event for professional wrestling than WWE's self proclaimed annual 'showcase of the immortals'. Each year, it's perpetually riddled with unabashed spectacle, defining moments of various wrestlers careers and creating countless future video package staples that transcend the context of the business itself. It is by all accounts - wrestling's must-see event. The scale and importance of WrestleMania is clearly at such a forefront in the minds of WWE's hard-working creative forces, that it often provides a large quantity of moments that will set the rest of the year in motion. There's everything from shocking championship wins, to the pulse-quickening token Undertaker match. But occasionally, there are also huge face and/or heel turns that can change the landscape of the company, or sometimes just the careers of those involved, for the foreseeable future. Take WrestleMania 13, at which Bret Hart and Stone Cold Steve Austin flawlessly executed what is known as a 'double turn'. Hart entered the match as a pure babyface, and Austin swaggered in as a heel. But gradually as the bout progressed, the two switched places, culminating in the image of a bloodied Austin in excruciating pain, trapped in the sharpshooter and eventually passing out in a pool of his own blood. Expertly done. Or alternatively take 2004's WrestleMania XX, at which Trish Stratus turned heel against Chris Jericho, to side with Christian in what many call one of the greatest examples in women's wrestling history. Face and heel turns at WrestleMania are a tradition, highlighting WWE's 'unpredictability' on the grandest stage of them all. Each year there's heaps of speculation regarding who might turn on the big day, and there's no exception for this year. WrestleMania XXX has a card that could very easily be one of the best in recent memory, with a set of stellar main events already sparking up with their promo-laden wheels in motion. But to top these off, there just has to be one, two or maybe more face or heel turns on the cards. Here are 10 face and heel turn possibilities that could (in theory) take place on the night of WrestleMania XXX:
