NXT call-up that exceeded your expectation?

Have any NXT call-ups actually exceeded your expectations of them?  I think the only one that has exceeded my personal expectations has been Elias.  Everyone else has either disappointed, or been about right where I thought they would be.  

Definitely Elias.  I'd also add Alexa Bliss, who was mostly a manager in NXT and is suddenly a multi-time champion on the main roster.
