#3 Vladamir Kozlov

Ukrainian-American wrestler Vladimir Kozlov signed a developmental deal with WWE in 2006, getting his proper main roster call-up in 2008. To emphasize the strength and intensity of Kozlov, he did not have an entrance music or a titantron video, instead he approached the ring in darkness with a spotlight following him.
Kozlov was quickly in the championship picture, competing in a bunch of qualifying matches within ECW programming. After Regal turned on Kozlov in late 2009, Kozlov turned babyface.

Shortly after joining the Raw roster, Kozlov was paired with WWE's main comedic wrestler Santino Marella. The two would compete in a dance-off before becoming a tag team. Ultimately, there would be a segment in which Kozlov and Marella hosted Sheamus for a tea party.
But more importantly, Kozlov was expected to dance, and he did dance plenty more times before he left the WWE in 2011. Undoubtedly Kozlov became less of a feared competitor as a result of his dancing, although Kozlov now works steadily in movie projects as an actor and producer, so it appears that things worked out just fine for him.
