In the WWE, this was Batista's new gimmick in that EVERYTHING had to be about him. His entrance? Every other light in the arena going off and a single spotlight being focused on him as he walked to the ring. Is he not in the World Championship match going on? He would run in and beat the crap out of both participants for daring to not have him in the match. If he cuts a promo, he will say this line at least twice.
In TNA, Dixie Carter's decision to fire Abyss. She was shown bullying General Manager Eric Bischoff into enforcing her wishes, which is admittedly her right as his superior. The problem here is that she wanted to fire Abyss not because he has been randomly attacking and trying to kill high-profile wrestlers (such as his assault on then-TNA Champion Rob Van Dam, forcing Van Dam to vacate the title), but because Abyss took Dixie hostage in front of the TNA "Impact Zone" (what TNA calls its in-studio fan base) and reduced her to a sniveling wreck on national television. She even orders it to be public just to humiliate Abyss just as he did her. She's already been put into harm's way before (via Fortune, which led to her husband Serge being assaulted in an attempt to come to her rescue) and she didn't bother to at least suspend them. Abyss's actions aside, this makes Dixie comes across as caring more about herself and how she appears than the well-being of her employees. When she talked to RVD about his match, the discussion was "I want you to beat him for what he did to me! ...Oh, and to you, too!"
Subverted in that Hulk Hogan and Eric Bischoff were actually working Dixie; they were the ones that had Abyss become an Ax-Crazy monster, carve up Rob Van Dam, warn maniacally about the coming of a force called "They"/"Them" that was telling him to do everything, and finally grab Dixie in order to frighten her into signing a contract Bischoff presented and said was for the firing of Abyss following Bound for Glory…but was actually for them to take over the company. Ironically, this trope built the motivation behind not just Hogan and Bischoff, but everybody involved in their Massive Multiplayer Scam.
For example, Wade Barrett ruined two groups as a leader/mouthpiece by this trope. First was The Nexus, who he risked his own contract to get on the show at first and treated as equals in various ways including promo time, but as soon as opportunity came to control and humiliate John Cena he turned Nexus into his anti-Cena group and had fun enslaving Cena for a few months while nothing else was happening for the group. This led first to David Otunga being The Starscream, then the entire group revolting and throwing him away for CM Punk. Fortunately, Justin Gabriel and Heath Slater preferred him to the cult-directing Punk, so they and Ezekiel Jackson joined him on Smackdown in the Corre. He insisted that they were equals, there was no leader, and he had learned his lesson, but then a #1 contender battle royal popped up and he said the Corre would be helping him win and it all deteriorated from there. Within two months, Jackson was kicked from the Corre and Slater and Gabriel disbanded it, all because of Barrett's insatisable ego and greed.
Doesn't end there, though. Slater and Gabriel stayed partners and friends after the end of the Corre, but that only lasted a couple of weeks. They fell out and became this trope themselves, with Slater saying in pre-match promos "I want my spotlight, cause I'm the One-Man Rock BAND, baby!", whereas Gabriel was actually working on a Heel-Face Turn while the hook of his then-new theme song, "All About the Power", which within a month was transferred to Otunga and Michael McGillicutty in their final period as the New Nexus (and is still Otunga's theme today), says this exact line three times within fifteen seconds.
The tenure of John Laurinaitis as General Manager of both Raw and Smack Down may have been supposedly based on the idea of "People Power", but as evidenced throughout his run, that was nothing more but a blatant lie, as Laurinaitis used his power to benefit his own personal gains and to trample anyone who got in his way.
CM Punk's 2012 Face-Heel Turn has him doing this, demanding everyone show him respect while showing everyone disrespect. When The Rock came out to rescue John Cena from a beatdown by The Big Show, Punk angrily assaulted The Rock, accusing him of disrespecting him by "hogging the spotlight from him." He'll often interrupt other people's promos and matches, saying they're hogging the spotlight.
This wasn't entirely unjustified — Punk was constantly overshadowed by non-title matches involving John Cena despite being the WWE Champion, and a lot of people agreed with him on that, especially when Cena's match with John Laurinaitis got higher billing than his. What's heelish about all this was best stated by Punk himself:
"It's all about the WWE Champion... which just happens to be me."
A common reaction to his sudden retirement in 2014 was the feeling that, rather than being some sort of statement against WWE's policies, Punk walked out on his contract because they refused to let him take the spotlight away from the lower card.
Generation Me. Despite being a tag team and brothers, Max and Jeremy Buck say this line constantly, and make it clear that they would sell each other out in a heartbeat to get ahead.
Evolution's purpose, even though it wasn't clear at the beginning, was to keep the World Title on Triple H. Hunter's jealousy over Randy's first world title reign (which he won off Chris Benoit, someone H was never able to beat on his own) is why Randy got kicked out — something Hunter would regret five years later when Randy finally completed his descent into insanity and started targeting Hunter's family, the McMahons, in retaliation for what happened with Evolution.
Brodus Clay's Face-Heel Turn in 2013 became this trope, after lending the rookie, Xavier Woods and R-Truth, he began bullying Xavier Woods and calling himself a "Main Event Player" constantly. This attitude change of his ultimately broke up his partnership with Tensai and he continues to call himself a Main Event Player.
