#4 Black Mass
As Tommy End, Aleister Black tore it up all over the independent scene in Europe for a decade, and while many people worried that he wouldn't translate to the WWE, he's done a fantastic job, and become one of the most promising stars in the entire company. The hybrid striking/high-flying style means that Black can adapt to all styles of matches, as we saw during his time with NXT, and now that he's on the main roster, it's time for him to rise through the ranks.
Right now, Black is teaming with Ricochet, and while that's a great tandem, he's a main event player waiting to happen, and all main event stars need a great finisher, and Aleister definitely possesses one. The Black Mass may be a simple spinning heel kick, but it's been built up so well through NXT and sold so well that it looks incredibly devastating, and like the RKO, it can come out of nowhere, and that's what earns it this place on our list.
