9. Seth Rollins: Colby Lopez
Can’t imagine Rollins winning a World Title using the name Colby, although he did use his real name out on the Indie circuit when he first began in 2005. Signing with ROH in 2007, Seth was completely re-branded into his new persona of Tyler Black. He would take the promotion by storm and later win the ROH World Championship. Soon after, he left the company for a shot at a promising WWE career.
Signing in August of 2010, Rollins made his debut in a dark match using his prior name of Tyler Black. Once he would begin with FCW, Black was officially renamed to Seth Rollins, a name we can safely say that stuck with him throughout his rise to the top. Following his FCW stint, Seth would join the main roster as a part of the Shield angle. He’d go on to become the top heel in the entire industry and he’s now trying to do the same, this time, as a babyface on the Raw brand.
