Arch-Enemy: He and Dolph Ziggler once feuded almost nonstop for the midcard titles. They've occasionally revived their feud over the tag titles. Randy Orton qualifies as well. Epico & Primo, and The Prime Time Players while tag champ, the former with Bourne and the latter with Truth. Wade Barrett's become one recently, as has The Miz.
Awesome, but Impractical: The S.O.S. (an arm trap somersault STO), which involves flipping himself and his opponent over rather awkwardly. It looks cool, but it's hard as all hell to execute, which is probably the reason it's never become his primary finishing move. In fact, the Japanese wrestler who created the move, Madoka (no, not that Madoka), performs it at high-speed to minimize the time of its intrincated motion.
His Trouble In Paradise finisher. It's a spinning kick to the face that can be executed on nearly anyone from nearly anywhere - including from the ring apron.
There was on time he pushed The Miz into the ropes, not even a foot away from him, and managed to land one of the nastiest kicks to his face, knocking him out cold. Give Kofi a chance and he will literally pull the kick off anywhere.
Berserk Button: Don't mention his relative lack of success during his singles run. Not if you know what's good for your health. (See the trope below.)
Beware the Nice Ones: This is why Shelton Benjamin had such a losing streak against Kofi Kingston, because he kept pushing his buttons or trying to intimidate him. Then in one of the WWE's most triumphant examples, he came after Legacy after they beat him up and blamed him for team Raw losing bragging at the bragging rights pay per view. Randy Orton would blame Kofi for his loss to John Cena later that night, since Legacy were suppose to help him win but the subsequent feud Randy sparked brought out levels of mischief and anger we had never seen in Kofi before.
This poor guy can not seem to catch a break, especially as far as tag team partners go. First, his reign with Evan Bourne was ended abruptly when the latter had a second Wellness Violation. He would later suffer a career-threatening injury to his foot, and hasn't been seen since. And just when it seemed like WWE had done him a solid by teaming him with R-Truth (who also served a suspension stemming from the same incident), Truth has also been written off television again due to a broken foot.
Not to mention every time he lost the tag titles, it was on a house show.
Subverted in the R-Truth case. Truth got better and he and Kofi became Tag Champions. Even when they dropped the belts, it was at Night of Champions.
Continuity Nod: After losing the Tag Team Titles to Team Hell No, Kofi and Truth split amicably as a tag team. They're still depicted as very good friends, though, to the point where their respective midcard singles feuds (Kofi as the IC Champion defending against Wade Barrett, and Truth as the challenger to Antonio Cesaro's US Title) have almost overlapped at points.
Everything's Better with Spinning: Zigzagged. His moveset's notably low on lucha libre-style moves (that is, for lack of a better descriptor, the "flippy stuff"), but a spin's the one thing that separates his Trouble In Paradise from...well, just a kick. Justified, however, as the way he does it really would transfer the momentum to the kick.
Fake Nationality: Was billed as being from Jamaica in NECW at a booker's suggestion. "Everyone knows reggae music and Bob Marley" being her reasoning. This kept up all the way until WWECW but it was eventually revealed on Raw he's from Ghana, West Africa.Justified when Triple H questioned him about his lost accent and he explained he was paying tribute to the Jamaican culture.
Five Moves of Doom: He tends to finish tag team matches off a sequence of four signature moves followed by Trouble in Paradise.
Genre Savvy: Might have had a moment like this after a recent rematch with The Miz. Miz tried to shake Kofi's hand after the match. Kofi responded by dropkicking Miz in the face.
His 2013 Championship win against Antonio Caesaro. During a championship match, it is very rare that someone will be able to measure up their opponent and then pull off their finisher...so while he was getting up after a failed pinning attempt, Kofi pulled out Antonio's leg and then used Trouble in Paradise to knock him out.
Ignored Enemy: Sometimes he's taken for granted by opponents with seemingly bigger fish to fry. Some people - like Chris Jericho and Randy Orton, for instance - have found out that this only makes him angrier, and isn't a good idea.
Aesop Amnesia on Orton's part occurring when he faced off with Kofi on the January, 13 2014 episode, thinking he could take out his anger at The Authority on Kingston. Instead, Kofi counters Orton's trademark DDT into an SOS for a shocking three count!
Once saved himself from Elimination in the Royal Rumble by walking on his hands outside the ring, all the way to the steps. The rules state that a competitor is eliminated if he (orshe) goes over the top rope and both feet touch the floor.
And again in the 2014 Rumble, where, after having been caught and placed on the barricadenote as part of a revenge beat down by a recently eliminated contender, Kofi made a running jump from the security barricade to the ring apron, a distance of more than seven feet.
In the same match, he survived by the tip of his toes.
Mr. Fanservice: When he went after The Miz during a segment involving them both and Larry King, a tux-wearing Kofi removed his jacket, tie and shirt. Audible female screaming could be heard from the audience.
No Man of Woman Born/Exact Words: Played straight in his U.S. Title win against Antonio Cesaro, where the latter boastfully declared that no American could beat him for the title. Kofi, of course, is from Ghana.
Offscreen Moment of Awesome: A subversion; Won the Intercontinental Title from The Miz in a match that was (apparently) very acclaimed by wrestling dirtsheets and the IWC. Miz only shows up on Smackdown on Friday after the fact and without his title. But this moment wasn't offscreen if you happen to have the ION channel, which is the cable network on which WWE's new B Show, WWE Main Event, aired the match.
Red Baron: In 2013, WWE took to calling him "The Wildcat", though it has not really caught on with the fans
Running Gag: Kofi's developed a reputation for being the hardest man to eliminate from the Royal Rumble; every time he enters, he does something entirely unexpected to save himself and get back in.
The Rival: From all the way back in Deep South Wrestling, Montel Vontavious Porter. They had a friendly rival mostly, and MVP symbolically passed his torch onto Kofi.
Not-so-friendly, though, with The Miz. The two just don't seem to get along, and anytime they're in the ring together, bad things tend to happen.
Signature Move: Double Leg "boom" drop, jumping forearm, top rope cross body block in tribute to Ricky Steamboat, Frog splash to rising opponent's back, double open handed chest strike, a Koronco buster followed by five punches on the top rope.
The Scapegoat: Legacy blamed him for Raw losing the Bragging Rights match to Smackdown, since Kofi was the one to get pinned, rather than on The Big Show who betrayed Team Raw by pushing Kofi off the top rope.
Not only that, but in his Traditional Survivor Series tag team match against Team Orton, he pins both CM Punk and Orton -two former world champions- in 6 seconds, becoming the sole survivor of the match.
He beat Randy again on January 13th, 2014. Let this sink in: he's pinned the WWE World Heavy Champion. Twice.
