There Is No Kill Like Overkill: Professional Wrestling
During the pre-1990s era, a common practice to help push Monster Heels – especially large super-sized musclemen – as unstoppable, feared, bloodthirsty forces (at least on syndicated television) was to have said heel continue beating their opponent, applying a submission hold, or delivering the finishing moves multiple times to a hapless jobber long after the victory was recorded. Naturally, the heel would then grunt out that he wanted to do the same to the top babyface of the organization, thus setting up the anticipated feud.
King Kong Bundy: During his mid- to late-1980s run as a monster heel, he often insisted that referees count to five (instead of the usual three) when counting the pinfall after delivering (sometimes multiple) avalanches to hapless jobbers, to push himself as an unstoppable force.
In WWE, wrestlers who have been feuding long enough will pull off something that garners this trope. One example involves The Nexus beating the hell out of people, though their favorite punching bag John Cena pulled this off himself at TLC 2010 where after beating Nexus leaderWade Barrett, he pulled a table on top of him and then dropped a series of supposedly decorative steel chairs suspended by a cable on top of him.
Heels are more likely to pull this trope on regular episodes just because they can.
The Rock once hit Mick Foley with SIXTEEN chair shots... Yes that's nearly half of Sheamus' total, but Mick's hands were cuffed behind his back, and each shot was directly to the face and head.
In CHIKARA, "Lightning" Mike Quackenbush got himself disqualified by hitting his nemesis 17 with the Quakendriver varieties I-IV.
During his Iron Man match with John Cena at Bragging Rights 2009, Randy Orton tried to blow him up with pyrotechnics. In fact, this is pretty much Randy's modus operandi — other instances include that time he attacked Batista after he won the WWE Title from him at Extreme Rules, and that time he RKO'd Christiantwice on the announcer's table after Christian took advantage of the stipulations of their match and used it to win the World Heavyweight Championship. Note that during the latter, Randy was a Face.
