3 WWE Gimmick Changes That Made Careers and 2 That Destroyed 

#4 Gimmick that destroyed a wrestler’s career in WWE: Stalker of The Undertaker’s wife Sara (Diamond Dallas Page)

DDP

Even though Diamond Dallas Page didn't debut as a main event wrestler, he eventually became one for WCW. When the company ran out of business, DDP decided to try his luck in Vince McMahon’s WWF.

However, things never worked out well for the former 'WCW main-eventer' as the company provided him an awful gimmick. After being a babyface in WCW, Page became a stalker in WWF who would always stare at The Undertaker’s wife Sara. I don't know why the writers thought to give him a gimmick like that but I do know is that it certainly destroyed his status in the eyes of WWE fans.

Things might have changed for the WWE Hall Of Famer but an unfortunate injury coerced him to retire soon. DDP then left the company in 2002 but returned to the ring in 2004 and then joined TNA.
