#5 Michael Tarver vs John Cena
Tarver was one of the original Nexus members, but he failed to break out as a singles star and was released soon after the group disbanded.
Michael Tarver has since stated multiple times that John Cena had a beef with him. Tarver went on to say that Cena was threatened by the talent he possessed and purposefully fractured Tarver's arm during a WWE PPV.
John Cena never made a comment on these accusations and Tarver soon fizzled into obscurity.
#4 JBL vs The Blue Meanie
The Blue Meanie was one of the ECW originals, and a part of the group named "Blue World Order", a mockery of WCW's 'New World Order'. During the ECW One Night Stand PPV, the WWE and ECW wrestlers engaged in a chaotic fight at the end.
Meanie had been stating in interviews that JBL was a backstage bully and this didn't sit well with the former WWE champion. JBL decided to legitimately hurt Meanie during the chaos. Later, The Blue Meanie was offered a WWE contract for a brief run and he decided not to sue JBL.
Meanie, however, had the last laugh when he defeated JBL in a no disqualification match with assistance from fellow B.W.O member Steven Richards.
To put things in perspective, JBL has been known as a legitimate bully in the WWE locker room. Superstars both past and present have criticized the former acolyte for his brash mannerisms.
