Roaring Rampage Of Revenge / Professional Wrestling
Roddy Piper was the master of this, and defined the trope from a wrestling standpoint in his 1986 feud with "Adorable" Adrian Adonis. On the WWF Superstars of Wrestling episode aired September 27, 1986, Piper began to berate Adonis over his "effeminate" gimmick and the "Flower Shop" segment (the former as a gimmick offensive to wrestling, the latter because Piper considered it to be hosted by a "Piper wannabe"), but found himself on the wrong end of a three-on-one beating when former Piper allies "Cowboy" Bob Orton and "Magnificent" Don Muraco helped Adonis instigate a horrifically brutal beatdown and destroyed the old "Piper's Pit" set. The trope kicked in the following week when Piper – who was feared dead or in the very least hospitalized with a concussion and multiple other injuries – came out with a crutch and, in a blind frenzy, destroyed the set of "The Flower Shop," before — with large amounts of spit foaming from his mouth — screaming out the words, "THE WAR HAS JUST BEGUN!" Eventually, Piper took out Muraco and Orton and then turned his attention on Adonis; after several delays due to legit injuries by Adonis, Piper and Adonis finally met at WrestleMania III, where Piper won a "retirement match."
Sting spent most of 1997 beating various members of the nWo with a baseball bat as revenge for their ruining his reputation and taking over WCW. While the nWo grew and grew, Sting never had any trouble beating them senseless; any time he appeared, the scene would end with the ringside area being filled with the beaten and unconscious bodies of mooks in black-and-white while Hulk Hogan and Eric Bischoff fled, yelling impotent epithets back at Sting.
In one memorable episode of WWF Raw is War, "Stone Cold" Steve Austin used guerrilla tactics to eliminate the members of Vince McMahon's goon squad, one at a time. He eventually trapped Vince himself in the ring, threatening his boss' life with a gun before revealing it to be a prop, as when he "fired" it, a flag popped out reading, "Bang! 3:16". This didn't stop Vince from completely wetting his pants, however.
Randy Orton (along with then-tag-team partner Edge) was also the victim of a Shawn Michaels RROR. Orton and Edge, along with an inopportune quad tear have taken out Triple H, and they're not exactly shy in telling everyone so. Shawn pulls Hunter's sledgehammer out from under the ring and proceeds to kick the everloving hell out of them.
John Cena succeeded in taking part in one against The Nexus for cheating him into being their slave and then Nexus leader Wade Barrett treating him horribly and forcing him into choosing between losing his career or ruling a match in Barrett's favor so he would become champion and be free. He chose to lose his career, ironically making him free to make Nexus' existence a living Hell. Subsequent weeks had Cena attacking Nexus members at random, eventually forcing Barrett to make a match between the two at WWE TLC. The match ended with Cena completing his mission as he handily beat Barrett.
In CHIKARA, Mike Quackenbush went on a rampage against the Power Stable GEKIDO for breaking his arm and putting him on the shelf for months. Quack broke 17's fingers at Chikarasaurus Rex: How to Hatch a Dinosaur, and engaged in some uncharacteristic post-match brutality against AssailANT and DeviANT at King of Trios 2012 that made even his best friend, Jigsaw, try to talk some sense into him.
Dean Ambrose. Ever since he betrayed The Shield, Seth Rollins cannot go a week without Dean trying to attack him in some way. Not even being Curb Stomped on the head onto cinder blocks could stop Dean Ambrose from trying to get his hands on Seth Rollins a month later. The kind of deep, personal loathing Dean has for Seth for betraying his trust is incomparable — Dean's only goal in life is to beat Seth within an inch of his life.
