#4 Conor McGregor
The Irishman’s epic rise to prominence is so incredible that it’s hard to remember the regional fame that he had gathered in Ireland before being signed to the UFC.
Considering the fact that he exudes stardom, the UFC immediately knew that they had something special on their hands when they signed the Irishman, but the seeds of that stardom were planted during McGregor’s time fighting for the Cage Warriors promotion.

When McGregor began his career as a feisty Dublin boxer testing the waters of MMA, he was finishing opponents similar to the way he is now, just without the same magnitude. Competing in the UK-based Cage Warriors promotion, he became a two-weight world champion, holding the featherweight and lightweight titles simultaneously.
His double title hold in Cage Warriors was his inspiration for his historical triumph in the UFC, where he repeated the feat and solidified his legacy by becoming the first man in the promotion’s history to hold two World titles simultaneously, at UFC 205.
