#3 Ryback
Under the name of Skip Sheffield, Ryback debuted in the main roster as a member of the Nexus. He annihilated the locker room under the leadership of Wade Barrett there. However, a broken ankle halted his run and he had to be taken out of action.
After returning, he donned the role of a human wrecking machine. He would squash various jobbers and lead the audience in chanting "Feed Me More." This gimmick even landed him a match against CM Punk for the WWE Championship at Hell in a Cell.
In the following four years, he feuded with the likes of Shield, Chris Jericho, Authority, Bray Wyatt, Rusev, and Kalisto. On May 2, 2016, WWE sent him home from television due to a contract dispute. Thereafter, we came to know that they had been on bad terms. Ryback wasn't happy with WWE's pay structure and vented out his creative frustration by posting this on his Tumblr page the next day:
Why not pay the talent equally? The winners have more MERCH as it is or are supposed to anyways so they get that extra perk, but why make the guy who is told to and agrees to lose earn less and sacrifice spots in big pay per view match ups etc. This is one of the major problems with wrestling and WWE today. Most guys take great satisfaction in helping making other talent, the bitching and the moaning we always hear about stems from the fact they know they are ultimately over time going to make less and live in fear of being released.
On August 5, Ryback announced on his Instagram that he and WWE had parted ways. WWE confirmed so by announcing it three days later.
