#1. Lars Sullivan was advertised for WWE's Monday Night RAW but failed to appear
Lars Sullivan was one of the most dominant forces in NXT throughout his time on the brand before he was called up to the WWE main roster - alongside a number of other faces including Nikki Cross, Lacey Evans, and Heavy Machinery.

Sullivan was set to make his first appearance on an episode of RAW in January 2019, but "The Freak" failed to make his debut alongside the other up and coming NXT talent.
Instead, it was revealed following the show that Sullivan had suffered a panic attack backstage and was then sent home by the company. Once again, this was a last-minute decision that forced WWE to make a number of changes to the show.
Sullivan did finally make his main roster debut the night after WrestleMania a few months later when he attacked Kurt Angle. The imposing Superstar was only a few months into his main roster run, though, when he suffered a knee injury in a handicap match against The Lucha House Party.
Sulivan is currently on the sidelines, but could be a surprise name included in the upcoming WWE Draft later this week.
