"My name is Damien Sandow, and these tropes are here to help you.":
Ain't Too Proud to Beg: Went the whole nine yards when Cody threatened to chuck the World Title MITB briefcase in the Gulf of Mexico, from admitting Cody led Rhodes Scholars and being Damien's intellectual superior to having better facial hair and being more handsome, pretty much backtracking on everything he said about being above Cody. Cody saw through this as well, mockingly telling Sandow "you've earned this" before tossing the case into the water.
Affably Evil: He just wants to "enlighten" the WWE fans (make them less stupid), but he goes about it in an arrogant manner.
Has a showboaty elbow drop he calls the Cubito Aequet (Elbow of Disdain). Careful examination of the Latin language will reveal that the second word is translated as distain, which means "to discolor" or "to sully," and thus makes no sense in this context, although it may be a hint that Sandow isn't actually as smart as he presents himself to be. The correct name is Cubito Fastidia.
His Finishing Move, a straightjacket neckbreaker, is called Terminus (pronounced "ter-mi-noose"), or "The End."
Badass Bookworm: Your teacher, Matt Stryker claims that Damien Sandow makes him look like a mental midget and only got one question wrong on his SATs because it was spelled wrong. Sandow himself claims he has studied every WWE wrestler to know exactly how long they can go before becoming fatigued.
Badass Long Robe: His standard entrance attire is usually a brightly colored robe.
Bad Santa: For 2013's Christmas episode of Raw, he was literally referred to as "Bad Santa", publicly announced his plans to cancel Christmas, and appeared in a skit where he insulted small children before a match with Good Santa (i.e. Mark Henry), which he lost.
Also with Brodus Clay, who he repeatedly ambushed and assaulted. When they finally have a straight match, Brodus spends most of it beating the crap out of him, only losing when Damien cheats and grabs his tights. And after that, Damien finds himself on the receiving end of Brodus' wrath.
Breakup Breakout: He is currently a much bigger star than his former tag team partner KC James. Inverted with the Rhodes Scholars as Cody has gotten a bigger push out of the two.
The Cast Show Off: Sandow's recently done some parody singing on the JBL and Cole Show and even occasionally on Raw. He's pretty good
Catch Phrase: Begins his promos with "Allow me to beg your indulgence. My Name is Damien Sandow, and I'm here to help all of you." Ends his promos - and occasionally his beatdowns - with "You're welcome." Also tends to use "I do this for the benefit and the welfare of you, the unwashed masses"
Combat Pragmatist: His cash in for the WWE championship actually went further than most money in the bank winners, not merely waiting for the champion to get injured or be beat down but both and then further beating him down himself with the briefcase.
Cutting the Knot: Did this in a literal sense when presenting the challenge of the Gordian Knot. Sheamus was attempting to solve Sandow's Gordian Knot puzzle, when Sandow took the knot and cut it.
Difficulty Spike: After his Tag Team Partner, Cody Rhodes, was Put on a Bus due to injury, his most recent gimmick involved him "searching for an apprentice" by calling a random person from the audience up into the ring and asking three questions to test their intellect. The first two are usually easy enough that almost anyone with a basic education can get them right, but the third ends up being a question better suited for the Million Dollar Question in Who Wants to Be a Millionaire?. This gimmick was dropped when Cody Rhodes returned and Team Rhodes Scholars was reformed.
Do Well, But Not Perfect: Damien put a quiz detailing the history of the WWE on the organization's website which mocked participants as sub ignoramuses if they did terribly and cheaters if they got them all right.
Finishing Move: Initially, cross-arm/straight jacket neckbreaker, which has been dubbed "Terminus" (Latin for "over" or "end"). Then (and very briefly), a sitout side slam he calls the Silencer. Currently, a full-nelson side slam called "You're Welcome."
Genre Savvy: During the Money in the Bank ladder match, he hid for the majority of the time, and only re-entered the match when everyone has been laid out and Cody was on his way to victory.
Hypocrite: Claims to be more refined than anyone else in the building, but his wrestling attacks are every bit as savage as Randy Orton's.
Claimed to be intellectual and professional equals with Cody Rhodes, as well as promising that neither man would prevent the other from achieving greatness. Cue Money in the Bank, where Cody seems primed to take the briefcase and Sandow unceremoniously dumps him off the ladder to claim it for himself. Then the following weeks would see Sandow saying that he was smarter than Cody and that he "taught him everything he knows" in the ring.
Insufferable Genius: The basis of his feud with Sheamus, where Damien Sandow would repeatedly outsmart him or cheat him and then flaunt in Sheamus's face till Sheamus kicked him.
It Will Never Catch On: TNA refused to even put Idol Steven in a dark match, so he went to WWC, reinvented himself and went back to WWE.
Mean Character, Nice Actor: He plays the obnoxious know-it-all to perfection, but during an episode of WWE Main Event,Cody Rhodes took a nasty fall that left him with head and shoulder injuries. Cody and a lot of fans noticed that Sandow refused to tag Cody back into the match after it happened and prevented the injury from getting worse. Cody later thanked him saying it probably saved his career.
In 2014, he was spotted on the street giving $10 bills to homeless people. Hardly anybody was there to witness it, meaning that was purely an act of kindness rather than a publicity stunt.
Minor Insult Meltdown: Sandow was supposed to wrestle Yoshi Tatsu, but deemed him an unworthy opponent. He beat him up anyway when Tatsu called him "chicken"..
Mythology Gag: Haddad's stage name is an apparent homage to Billy Sandow, a member of the "Gold Dust Trio" which was influential in establishing wrestling as a worked sport in the 1920s.
Rock: Let The Rock ask you one final question and if you get it right, you'll get an amazing prize from The Rock here in Miami: What happens when you combine a geological aggregate of minerals with its lowest form?
Sandow: That would be, you would get 'rock bottom'!
Rock: Exactly. *Rock Bottoms Sandow*
Screw This, I'm Outta Here!: Pulls these when he's put in matches that are made on the fly, as he wants to study his opponents and exploit any weakness they may have.
Smug Snake: So much so that if he ever pulls one competitive dick move on a friend, it hangs in the air like a neon sign saying "DO NOT WANT" all over said friendship. Just ask Cody Rhodes.
His theme song "Hallelujah" makes sense when you remember his former ring name "the idol" and his current claims to be an intellectual savior.
The Snark Knight: Feels no one is of his caliber (aside from Cody Rhodes at one time), and regularly makes comments belittling those beneath him, using sarcasm and facial expressions. His Outside The Ring videos show this clearly
Spot of Tea: On Twitter, many of his (or rather, "Ignatius" his supposed personal scribe's) tweets are regarding what type of tea he is drinking.
Super Drowning Skills: When Cody Rhodes threw Sandow's Money in the Bank briefcase into the Gulf of Mexico, Sandow revealed that he can't swim, and then nearly drowned trying to retrieve the briefcase.
(in the WWC [World Wrestling Council] in Puerto Rico): The American Family, w/Shawn Spears
(in OVW): The Jersey Shore Crew, w/Nova, Danny Infernonote Danny Gimondo, aka Inferno or the Inferno Kid and Trudi DeNucci.
The Teacher's Pets, with KC James
Team Rhodes Scholars
Viewers Are Morons: The original "WWE in Roughly Five Minutes" videos on YouTube (since removed, though they can be found elsewhere on the Interwebz) began a segment called Understanding Sandow: A Simple Guide for the Feeble-Minded.
Sandow: Deplorable, contemptible, and abhorrent.
Translation: Bad, bad, and bad.
Sandow: This is not what our Founding Fathers had in mind as they were fighting for our independence.
Translation: This isn't what John and Ben and those other dudes wanted you to do with your free time.
Sandow: And the Intellectual Savior of the Masses and Your Martyr, I am obligated to rid the WWE of all foolishness.
Translation: I'm pretty smart and a bro, and I don't like silly stuff.
Sandow: Any man who engages in a ridiculous activity such as dancing...
Translation: Men dancing is silly and the Dougie is stupid...
Sandow: ...serves only to contribute to the delinquency of our society.
Translation: ...except when Kate Upton does it. Anyone who isn't her should stop.
Villain Team-Up: With Cody Rhodes, calling themselves Team Rhodes Scholars, who Damien says is the only guy on the roster that he can have an intelligent conversation with (which is hilarious when you consider who Cody's father and brother are.) After a couple months as a tag team, they went their separate ways, but vowed to to remain best friends... or at least that was the plan. The two continued to support one each other regardless and reunited only a month afterwards.
Villainous Friendship: Type 1. The two legitimately enjoyed one another's company and considered the other their best friend. Until…well…see Smug Snake for a clue as to what happened.
Villainous Breakdown/Enraged By Idiocy: Had a minor one during the September 21 episode of Smackdown when Edge, Kane, and Daniel Bryan were in the process of "hugging it out" to get rid of their frustrations. Sandow came out and was doing his usual schtick when Edge asked the audience if they'd rather see Sandow face Kane or Bryan. After Edge kept repeating "Bryan or Kane?" over and over, Sandow went from being calm like he usually is to screaming "STOP IT! STOP IT! STOP IT!" Had another one when Rhodes deliberately threw his Money in the Bank briefcase during the July 26, 2013 episode of SmackDown.
Villainous BSOD: When he cashed in his Money In The Bank contract on John Cena and failed (despite him destroying Cena's injured arm beforehand and coming so close to succeeding), the look on his face in the corner while Cena celebrated just screamed this trope. There was no doubt that he was a broken man when this happened.
