The WWE Divas deserve special mention here. He seemed to save his venom for two very specific Divas, Natalya Neidhart and Eve Torres. While most of the Divas are accused of being Faux Action Girl Eye Candy, he decided to pick on possibly two of the most dangerous of them. Natalya is a veteran wrestler and a member of the Hart Wrestling Family. Eve is a trained Gracie Jiu Jitsu fighter, and is (in Real Life) dating a member of the Gracie Family. He decided not only to bully the two most dangerous female Dragons, he also chooses the two most-well connected.
In 2007, Santino Marella would regularly mock "Stone Cold" Steve Austin: mangling Austin's catchphrases, cosplaying as him while acting like an idiot, bashing Austin's movies and declaring him a horrible actor. When Austin finally confronts him face-to-face, he forces Santino to admit that he never actually watched any of his movies. Austin offers Santino a DVD of The Condemned and requests that he watch it before evaluating his acting skills, but Santino throws it down and stomps on it. Cue beatdown.
In the early months of 2012, Cody Rhodes made it his mission in life to mock The Big Show, calling him a fat loser and continuously showing clips of Show's embarrassing moments. No matter how many times Show catches up to him and gives him a No-Holds-Barred Beatdown, he just won't stop. Come WrestleMania 28, Rhodes ends up paying the price, as he not only got KO'd by Show, but he lost the Intercontinental Title as a result. Show then returned the favor to Rhodes, showing humiliating moments during his matches.
Chris Jericho's debut in WWE/WWF had him interrupting The Rock. That's one thing that few superstars, let alone newbies like Jericho, have the guts to do. However, his second appearance had him interrupting The Undertaker.
Damien Sandow interrupting the D-Generation X Army reunion. A rare occurrence where the bully openly acknowledges the consequences beforehand.
During Wrestlemania 6, Bobby Heenan slapped André the Giant for losing a tag team match against Demolition. Andre went bezerk and knocked Heenan out.
