#5 The Mega Powers Explode (WrestleMania V)
Breaking up a popular team, by turning one of them on the other, and then having them feud with each other is actually the simplest way of igniting a rivalry, and this is exactly what WWF did with WWF Champion Randy Savage and Hulk Hogan back in 1989. A perfect storyline laid out over the course of one full year, this was easily the best WrestleMania program WWE had ever produced till that point.
After Hogan assisted Savage to win the WWF Championship at WrestleMania IV, the duo started teaming together as The Mega Powers. With Miss Elizabeth as their manager, the dominant trio fought and defeated every single heel tag team in the WWF throughout 1988. However, Hogan's closeness to Miss Elizabeth in early 1989 led to some outbursts from Savage.
Things escalated further when Hogan accidentally eliminated Savage from the Royal Rumble and the two had a face-off thereafter, which laid the foundation stone of a Savage Heel turn. This was solidified when Savage attacked Hogan with the title belt in a medical room, where Elizabeth was being checked. It was the best WWE had ever done with a Mania storyline, and it led to one of the most anticipated bouts in the history of WWE.
