#3 Kalisto

For years WWE has been in search of the next breakout Latino star, and the company at one point had that in the sensational Kalisto.
During his time in NXT, Kalisto teamed up with Sin Cara as the Lucha Dragons, an exciting tag team that wowed the NXT fans in praised rivalries with tag teams such as The Ascension.

Kalisto definitely enjoyed a moderate amount of success on the main roster after being called up, and has been an important part of the WWE 205 Live roster, but Kalisto is a star who could break out and become a major player in WWE.
Should the company return Kalisto to NXT, and possibly give him a refreshed, maskless gimmick, the former NXT Tag Team Champion could return to the main roster as the Latin sensation the company has been looking to build.
With Eric Bischoff taking over SmackDown Live in the coming months, and his track record for showcasing Cruiserweight talents, Kalisto could return to NXT to be groomed for a call up to Bischoff's new SmackDown Live.
