Mephone is autistic/has ADHD !!!!!

1: Special Interests/Hyperfixations

He canonically has a fixation on reality TV, and has had this same never-fading passion for it since he was a child. It's often shown that he connects his interest with real life to try and understand it better, and at times his love and focus on it can get in the way of him doing chores or other important things. This is extremely similar (if not identical) to what having a special interest/hyperfixation is like for many ND people.

2: Stimming

Throughout the series, he's seen flapping his arms or moving around excitedly (especially when hosting his show and/or talking about reality TV)

3: Samefoods

(For explanation on what a samefood is, this tumblr post words it nicely) Throughout the entire series, a common running joke is Mephone's love for cookies, typically him eating them all himself when they were supposed to be prizes for the contestants. It's his comfort, and one of the few kinds of foods we ever see him eat.

4: Aversion To Touch

While it could also be due to trauma, he is shown to repeatedly avoid touch from others and panic when they do if it's not first initiated by him.

5: Lacking Sense Of Time

Due to most of the symptoms and issues that are inherent to ADHD, many with it have a very offset internal clock and have trouble with managing time and things because of this. Mephone has shown to have a similar problem, one of the creators even describing it as his internal clock being off himself.

6: Rejection Sensitivity

He canonically has PTSD (specifically parental trauma) and we see a few flashbacks of his trauma, many of them being him being yelled at, ignored, or having his interests be put down. Which could very easily be read as him having RSD. Additionally he gets especially defensive or upset when others put him down or make fun of him, which could also point towards this.

That's all for now! If you've read this far I am kissing you on the mouth platonically. (joke)
