#4: The Nexus
In June 2010, the WWE was rocked to the core, when the Nexus showed up.
A group of young, hungry rookies from Season 1 of the original NXT, the team would demolish everyone on Monday Night RAW, regardless of who the fans supported.
Perhaps the best example of their ability to intimidate is when they crowded WWE Champion Sheamus, forcing the Irishman to form an uneasy alliance with his rival at the time, John Cena.
A truly shocking team, the more eagle-eyed fans may have noticed that the Nexus were incredibly similar to Generation Next in ROH. Back in 2004 and comprising of Alex Shelley, Roderick Strong, Austin Aries, and Jack Evans, Generation Next also took no prisoners, and waged war on those in the main event.
Whilst the Nexus could've been WWE's own creation, the similarities are very striking.
