#3 Rusev
Rusev's story as one of the biggest self-made star is like a fantasy story. After struggling as mid-carder ever since losing his United States championship to John Cena, Rusev was paired with Aiden English. The odd pairing of English and Rusev, however, turned out to be a once in a lifetime pairing as the duo started a revolution.
What started as just any other normal promo, the concept of Rusev Day quickly got the attention of the fans. The chants for Rusev Day quickly became one of the most commonly heard chants in almost every arena. You can imagine the popularity of Rusev Day when the fans in Ring of Honor chanted for it during one of their shows.
The success of Rusev Day wasn't just limited to arenas and social media. Rusev Day merchandise quickly became as the number 1 selling merchandise for WWE Shop. The massive popularity eventually earned Rusev a shot AJ Styles' WWE Championship at Extreme Rules 2018. However, just like every other entry in this list so far, Rusev failed to win the big one.
