Seth Rollins, the CrossFit Jesus himself, is no stranger to polarizing the fanbase. Early on in his Ring of Honor days, he was a pure villain, part of the Age of the Fall stable along with Goth Princess Jimmy Jacobs and Necro Butcher. They attacked the Briscoes and hung Mark from the rafters ala the Undertaker.
Then he gradually became a solo act and wound up being ROH world champion. He also collected every other belt the promotion had to offer along the way. As Tyler Black, he turned a lot of heads in the industry, including the WWE.
Seth was brought into the developmental brand and groomed for the main roster. He made his debut as part of the heel group the Shield. Of course, the Shield was polarizing in and of themselves. They were ostensibly the bad guys, but there intensity and skill made a lot of fans cheer for them.
Of course, Seth was the first to betray the group and wound up on his own. He became a full-on heel for a time, but again his intensity and skill made a lot of fans cheer for him. These days Seth is universally cheered....for now.
