Broken Bird: He used to whine a lot on Twitter about his doubts and how insecure he is of his role as a good leader.
the beginning of 2014 was not kind to him at all, starting with the deaths of his father and his paternal grandparents.
Expository Hairstyles: Played with in Explorers of the Human Body. Since the others often joke about how Leeteuk could easily pass as a member of H.O.T., he does in 3 minutes the signature hairstyles of the idols of the 80s, 90s and 2000s.
It's even rumoured in the fandom that the company made them sign an agreement to reduce the amount of fanservice.
In September 2012, Kangin posted a screenshot of a message Leeteuk had sent him over a smartphone app. The caption reads "See(,) our relationship is like this", and in the messages, Leeteuk appears to be praising Kangin for something he had done and making him promise to always be there for him.
Also with Yesung. They are seen close to the other in many interviews, random takes on the street and some MVs
The Host: Another of his special skills. Even the MCs from the show he's invited to comment Leeteuk should be permanent co-host.
The Dreaded: In Intimate Note, the others reveal Eunhyuk once expressed that Heechul's pants didn't go with the performance they were going to do. Manager's answer?
Manager: If I make Heechul change, maybe we won't see Eunhyuk anymore.
(Worth noting Heechul never changed clothes in the end)
In the same episode, everyone kept repeating "We love milk-skin Kim Heechul", and later admited it was because they knew the consequences of living with him if they elected him as the meanest band member against Eunhyuk (worth noting that the only ones who still stood behind him were Hankyung and Sungmin).
Harmless Lady Disguise: He explained once in an interview that one of the reasons he adopted that fashion style was because he was tired of Yunho borrowing his clothes, so he started to choose anything Yunho would never pick from him.
He is also very protective of his close circle of friends, which include Kibum, Siwon and Donghae from the band.
His closest friends are also called the "Chocoballs": Hongki (to the point Kyuhyun complained about how he favored Hongki more than him being the maknae, to which Heechul yelled that it was because he wouldn't trick him into going to a reality tv show), Choi Mithra from Epik High, Jay and Jungmoo from TRAX.
Hidden Depths: Heechul also expressed interest in writing children books.
Hot-Blooded: The other guys told once that back in trainee days, Heechul is very territorial with his food. When Dong Bang Shin Ki's Jaejoong took one bite of his burger, Heechul snapped and left the table. Since then Jaejoong never took food from anyone.
Even invoked in Intimate Note, where he proclaims "If I'm on a show, I have to be the protagonist" (the episode was Kangin and Sungmin centric, and the others had to help them to bond). Second part of the special turned out he indeed was one of the main subjects, along with Eunhyuk.
Lolicon: If one considers his enthusiastic obsession with Wonder Girls'Sohee, who is almost nine years younger, as well as his close friendship with labelmate f(x)'s Sulli.
Motor Mouth: He also raps well. Listen to his rap in "Oops"
Put on a Bus: Went to fulfill his Mandatory Military Service in 2011.
The Bus Came Back: He returned in 2013, but officially performed with the others for the last runs of Super Show 5 and the 7th album in 2014.
Real Men Wear Pink: He is very proud of his fashion sense. Aside the fact that it's his favorite color, he also started to dress like this so Yunho, back when they were roomates, wouldn't borrow anything.
Troll: The first Korean words he taught Hankyung were profanities. And also did the same with Henry, teaching him pick-up lines.
Heterosexual Life-Partners: While the fandom mostly recognizes Ryeowook as such (for the Fanservice and the fact that they were roomates), Yesung is mostly next to Leeteuk in the MVs, interviews and other random takes on the street. And also there's Kyuhyun.
Momma's Boy: Most of his photo updates and song dedicatories go for her.
No Sense of Personal Space: It's revealed in an interview that the others remember Yesung has the custom of going to all rooms and touch their philtrums (upper lips) in the middle of the night.
There's also another interview where the others tell Yesung tends to forget his towel before taking a shower and leaves the bathroom with nothing on to look for it.
One Steve Limit: Kangin (Youngwoon) and Yesung's (Jongwoon) names are pronounced very similar. Both have Stage Names.
Put on a Bus: As May 6th, Yesung joined the army for his mandatory military service.
Trademark Favorite Food: Apparently in fanon, Yesung loves coffee. He even bought a coffee shop for his mother called "Handel & Gretel", he and other bandmates attended as baristas for the opening day. On his 2012 vacations he went to taste all the coffee shops he could encounter.
As of November 2012, he has opened another coffee shop called "Mouse Rabbit Cafe".
Arson, Murder, and Jaywalking: When they appeared on the show Intimate Note, Kangin listed his own faults as being playing favorites with the younger members, not rehearsing well enough, and gaining weight.
Big Brother Bully: He mostly fulfills this role in the group, especially because he often threatens the others with chasing them if they pull a prank on him.
Promptly the other guys back off quickly as soon as Kangin gets pissed off.
Another big example comes from EHB, where he started the trend of de-pant the other members on camera (they were using lycra shorts under, but it was still embarrassing for them). When the others tried to prank him as well, Kangin was Genre Savvy enough to tie his pants belt to avoid it.
Jack-of-All-Trades: Forever the outsider, not quite entering the ranks of the main vocalists or dancers (considered to be ranked fourth best for each, just after the respective Spotlight Stealing Squads (see below)). Also has an innate talent to pick things up far quicker than others on variety shows (ranging from bubble-blowing, to flairtending, to magic tricks... the list goes on).
Sungmin: Heechul hyung. About that time when we kissed.
Heechul: You're bringing this up again?!
Sungmin: I did it, right? Then why do you still hate me? LOL
Sungmin: In the end he said I did it better!!
Heechul: That already sounds weird!!
Real Men Wear Pink: LITERALLY. To the point he himself started to reconsider changing his wardrobe when he realized there was too many pink items there.
Renaissance Man: He's not only considered a great singer and dancer in a group with several members that specialize in those fields, he's an actor, MC, and a musical star. He's fluent in Japanese (even starring in Japanese musicals, which is a first for any Korean pop star), plays several instruments including the guitar and the bass guitar, and is a martial arts expert. He's also one of two Super Junior members that is in every sub-group (excluding SJ-KRY, but he has performed with them).
Sweet Tooth: He really likes sweets and deserts. His favorite vegetable is even sweet pumpkin.
Put on a Bus: After appearing in the promotional material for the 3rd album, Kibum didn't participate in any of the live performances. It was later announced that he was going to devote full-time to his acting carreer, also stating many times he didn't leave the band. Despite that, his profile is not shown in later Super Junior album profiles, instead only appearing as an individual actor in the SM website and fanmeetings (where he is presented as "Actor Kim Kibum" instead of "Super Junior Kim Kibum").
Sir Not-Appearing-in-This-Trailer: He only appeared in the trailers for "Sorry, Sorry" and "It's You", and only appears in the photos for the Super Show 2 concert, but went completely absent from Bonamana and so on.
Deliberately Cute Child: Kyuhyun may also be seen as this, although he tends to utilise the role of team brat to create this effect. Also, he gets automatic points for being the maknae (youngest).
The Determinator: He recovered from his post-accident rehab and was able to perform again, contrary to his doctor's predictions.
From EHB, He was the only one from his team to hit the center with his arrow after many hours of practicing. Let's consider he was fresh out of his physical rehab, which counts as a Crowning Moment Of Awesome.
Fan Nickname: Invoked by even by the members. Kyuhyun actually has infinite nicknames. One needs only to attach "Kyu" to a short word, as in TroperKyu. The possibilities are practically endless.
This subunit consists of Hangeng (who left the group in 2011), Siwon, Donghae, Ryeowook and Kyuhyun, plus Henry and Zhoumi,who are exclusive to this subunit. After Hangeng left, Eunhyuk and Sungmin were also added.In general:
Token Minority: Hankyung (while still in the band) was the first Chinese member, Zhoumi is currently the only Chinese member, while Henry is Canadian (his mother is Taiwanese and his father is from Hong Kong).
Omniglot: His native language is English, he is also fluent in Mandarin and Korean. In addition, he can also speak Cantonese, Taiwanese Hokkien, a little Japanese and Thai, and basic French, which he learned while in Canada.
Lately with FX's Amber, since both of them take a lot of selfies together having dinner, going to the gym, and also Amber featuring in two of his songs (his Super Show cover of "Baby" and "1-3-4 I love you"). They also happen to speak the same language, both are chinese descendants and are very similar.
Sixth Ranger: Subverted. He almost got to join, but the fans protested so hard that he only joined the sub-division M.
Full Name: Zhou Mi
Adorkable: Whenever he is Squeeing, he is this, contrasting with him not being one of the younger members and the tallest.
In his drama, he was tasked with punching fellow lead Calvin Chen twice. Each one of the punches appeared to have been made with the side of his hand.
Fans consider him to be quite shy, although he's a trained MC.
When f(x) was going to debut, he met with member Victoria and the two of them cried happily about it, despite everyone else celebrating.
As noted above, he loves shopping. When going on vacation, he takes an empty suitcase with him for purchases and almost always brings it back full. Sometimes he needs to buy another one while he's there.
He's been very thin since before his debut, and still is, gym time notwithstanding. Also tends to wear lensless glasses a lot and has had a variety of fancy haircuts.
Like Brother and Sister: He and Victoria were cast as leads for a Taiwanese drama. For the kiss scene, they couldn't help laughing awkwardly, and said they were like siblings.
