#2. Former WWE Champion Brock Lesnar
NXT was once seen as WWE's developmental brand, but in the past, the likes of John Cena, Chris Jericho, Batista, and even Randy Orton have all appeared on the show.
One name that doesn't make the list, perhaps unsurprisingly, is Brock Lesnar. Lesnar is seen as a part-time star in the company at present, and only returns when he is needed for a big-money match.

It's unlikely that WWE would ever pay the money needed to have Lesnar come back and wrestle a match for it to take place on NXT. This means that despite NXT alumni currently populating the best part of the company's main roster, Lesnar could always be the one who stands out.
At present, almost all of the Champions in the company came through NXT as well, with all of the Women's Championships being held by former NXT Superstars as well as the company's two main Championships.
There is only Randy Orton and The Usos, who currently hold titles but didn't come through the ranks in NXT.
