During the late 1980s, the Honky Tonk Man became the longest-reigning WWF Intercontinental Champion to that point, holding the title for nearly 15 months in 1987-1988. During promos, Honky bragged that he was the "greatest Intercontinental Champion" in history, but his claim had little to do with his actual skills; rather, he would frequently get himself disqualified or have his manager, Jimmy "Mouth of the South" Hart, sneak-attack his opponents to set up an easy win. When the Ultimate Warrior finally caught up with Honky at the inaugural Summer Slam in 1988, it took 30 seconds to dethrone the braggart Honky. Honky never did regain the title, and his bragging soon became ignored by the fans as just hot air.
The Alpha Bitch team of LayCool play with this. They refer to themselves as "simply FLAWLESS!!!" and one night, while doing commentary, asked "Why doesn't anybody like us?" This is after they've been Curb Stomped by every other Diva more than once and invented several nicknames for several of them such as Smelly Kelly◊, Piggie James◊, and The Belly Twins◊
Mr. Kennedy (Kennedy!) appeared to embody this trope when he exploded onto the scene in the late spring of 2006, claiming to be WWE's newest sensation and harboring such a high opinion of himself that he performed his own ring entrances in authentic ring-announcer style. He would often say that he was "the man who is single-handedly changing Friday nights!" The twist was that Kennedy actually could back up his braggadocio, defeating the likes of Batista and The Undertaker (albeit by cheating, getting his opponent counted out, or by goading the other guy into dishing out Disproportionate Retribution to him and gaining a disqualification victory). In fact, the only occasions when Kennedy seemed to come up short were when actual titles were on the line.
A meta-example: Drew McIntyre was pumped up by Vince McMahon as a future World Champion upon his debut and proceeded to let it go to his head. Since then, Drew hasn't caught on with the fans (in real life) but still thinks he deserves A-list treatment (in kayfabe), becoming this trope.
Alberto Del Rio, an arrogant, smug, cowardly, racist "thousandaire" who thinks it's his "destiny" to be the WWE Champion. He will repeatedly say he is the greatest undisputed WWE Champion ever, and he takes full credit for inspiring the walkout on Raw despite the fact that he had little to do with it other than complaining a few times about how unfair it was to him to have to be put in Hell in a Cell against John Cena and CM Punk, and much of the credit for the walkout actually belongs to his cohort, Christian, who himself is something of a Small Name, Big Ego. In fact, this could easily describe most of Del Rio's lackeys and allies, what with their constant complaining about how they're not getting the treatment they "deserve". This was toned down a lot after his brief Heel-Face Turn.
Announcer Michael Cole, with his Face-Heel Turn in late 2010. He frequently declares himself the "Voice of the WWE", takes pride in his past as a broadcast journalist, and likes to brag about his WrestleMania "victory" over fellow announcer Jerry Lawler.note Though in reality, it wasn't really an "earned" victory, per se, the Anonymous Raw GM overturned Lawler's victory in favour of Cole., as well as his "superior" wrestling skills due to the aforementioned fact. It got better once he turned back to face.
