#4 Trish Stratus
Trish Stratus is one performer who has been great at playing a babyface and a heel. And has been quite impactful at that. She began her career as being a valet for Test and Albert but was quite green as a wrestler and over the years she developed so well as a wrestler that WWE kept going a great deal to find a second version of her.
While she began as a heel, her most breakthrough moments were during the feud between herself, Christian and Chris Jericho. She spectacularly embraced the dark side at WrestleMania in a match with a ridiculous stipulation where Jericho and Christian were fighting to win her. She slapped the wits out of Jericho to assist Christian to gain the win. She then traumatized Lita for a great part of the year until the Queen of Extreme won the Women’s Championship from her in the main event of Raw in December 2004.
