Nope. In the meantime, can you give a list of things Discord would in-character when meeting someone like Dr. Clef?
Discord became a frequently reoccurring character during 1 of the seasons, & it's been years since I've watched MLP, & he has a wall of hax.
I do not remember his behaviour when meeting new, hostile or otherwise individuals well enough to be sure how he'd act.
He's often self-serving & interested in fun, as shown with how he needed time to grasp a lot of concepts of friendship, & as the embodiment of Chaos, what he might do is not something I'm uncertain of.
Some of it might be dependent on how Dr. Clef is, especially at a glance. How does he look & act & such? Besides that he's hostile?
Lemme re-read the Wiki a bit to refresh my memory.
For the seventh episode of season five, see Make New Friends but Keep Discord. For the twenty-second episode of season five, see What About Discord?. For the seventeenth episode of season six, see Dungeons & Discords. For Discord's secret identity in season nine, see Grogar. Discord is a male...

"When Twilight and her friends venture into the palace labyrinth, Discord prevents them from "cheating" in his "game" by magically removing the ponies' wings and horns. This enforces the first rule of his game: no flying and no magic. The second rule is that they must all play the game, or else he wins. He separates them in the maze, and the game begins. Discord confronts the Mane Six with trials that make them question themselves, causing them to contradict the elements they represent."
So in that instance, when the Mane 6 were coming to confront him, he did a form of Power Nullification & then Mind Manipulation.
"Twilight is upset when Discord takes away the maze before they can find the Elements of Harmony, until Discord reveals they were not in the labyrinth but back in Ponyville."
& apparently use of an illusion?
"When Tree Hugger soothes the Smooze back to normal, Discord becomes fed up and nearly banishes her to another dimension."
BFR. In context, Tree Hugger was a friend of Fluttershy's, & Discord had become jealous.
"Throughout the evening, Discord tries to steer things toward more enjoyable activities, but Spike and Big Mac insist on playing their game. Discord's disinterest in the game and frustration eventually drive him to create a real-life version of Ogres & Oubliettes."
A bunch of Reality Warping... which is an innately adequate description since Reality Warping inherently means involving other abilities. I'm just not sure which. He made the board game & the costumes & powers real, IIRC. Context: During a guy's night with Big Mac & Spike, Discord wanted to play other games.
"In A Matter of Principals, Discord gets so upset when Twilight leaves Starlight Glimmer in charge of the School of Friendship in her absence instead of him that he tries to sabotage her lessons and activities. When Starlight banishes his physical form from the school grounds, he terrorizes the students as a ghost. Starlight eventually realizes that the reason for Discord's actions is because he felt left out of the school, not even having been invited to its grand opening."
Context speaks for itself. Astral Projection, plus probably Possession & other stuff, depending on what he did, which I don't remember.
The MLP Wiki describes his Personality with, among other things:
"In The Return of Harmony Part 1 and Part 2, Discord is shown to be a mischievous and manipulative trickster who effortlessly pulls pranks on others through the use of his powerful magic, illusions, and hypnotism with little to no consideration towards his victims. He has a sense of showmanship and drama, preferring to be playful towards his victims before getting down to business, as seen when he mocks and banters with Celestia and the Mane Six in Canterlot Tower."
So yeah, I'm not entirely sure what he'd lead with.
Other MLP experts may be able to provide info.
