#9 Shayna Baszler
When we talk about stars who have transitioned from MMA to WWE, many out with the wrestling inner circle will think of Ronda Rousey.
But when it comes to impact on a particular brand, the former RAW Women's Champion is topped by her training partner and friend. 'The Queen of Spades' Shayna Baszler made the jump to professional wrestling three years before Rousey, training under the mentorship of independent stalwart Mercedes Martinez.
New Champs in WWE! More RIGHT HERE
This meant that by the time she arrived in WWE for the Mae Young Classic, she was close to defining a more all-round style in the ring. Her arrival in NXT in 2018 came after a period of domination from Asuka, and the brand's division needed a new leading presence.
In the 24 months since her debut on the Black and Gold brand, Baszler vanquished all that came before her. For all bar 14 days of 2019, she reigned as NXT Women's Champion - an incredible feat in its own right. The list of enemies she has bettered is impressive in itself - Kairi Sane, Ember Moon, Bianca Belair, Io Shirai and Candice Le Rae to name a few.
Baszler's place on this list is cemented with her win in the Survivor Series 2019 main event over Becky Lynch and Bayley, a win which gave NXT the victory on the night and showed that she was a force to be reckoned with going forward.
