Before we begin, I'd like to remind everyone that these summations are based on my understanding of the characters, and what I've observed of them within the games. Sometimes, that comes with a little bit of extra analysis and headcanons, which are inherently interpretive. Those headcanons are not to be taken as the Absolute Authority on the characters. These entire guides are not meant to be Absolute Authority. They're about giving a good look at the characters as they're shown to us, based on what I know.
Also, follow-up questions are always welcome.
Schezo Wegey is motivited entirely by a never-ending desire to gain more power. So he says.
First thing's first, let's discuss his accidental double-entendre's. While it's extremely tempting to try to force as many of them as possible in his dialogue (I know I've been guilty of it), he doesn't make those slips that often.
Generally, his freudian slips happen when he's excited, flustered, or irritated. Or in other words, when he's not taking the time to actually think about the words he's saying.
(He is, after all, trying to break the habit) (via practicing his speech to a handmade doll) (that he made himself)
The slip-ups are of greatest effect when he forgets to say a word, or says the right words in the wrong order, or mispronounces something (as opposed to, for instance, saying the word "come" with weird emphasis)
One good example that actually comes from Puzzle Pop (despite how he is in the rest of the game): "If you don't feel capable of doing this yourself, I'd be happy to play with [Carbuncle] myself for this next match."
Most importantly, it's unintentional. That's the whole point.
Amitie (and perhaps Lidelle) doesn't know what the word "creeper" means, but since Arle calls Schezo a creeper, she does too. It's more of an affectionate nickname than an insult, coming from her
Schezo's age is unknown. Granted, most of the cast's exact age is unknown, but Schezo stands out in that there's not a clear frame of reference of how old he is beyond "older than 14 and younger than Satan," which encompasses a rather wide range of possible ages.
Other characters usually address him as a young man-- which is noteworthy, since Satan looks like a young man but is immediately pegged as a geezer.
(Personally, I read him as in his early- to mid-twenties)
A fairly common interpretation (at least in my circles) of his history is that Schezo's mind/personality was corrupted as part of the process of inheriting the power and title of Dark Mage from Runelord.
This corrupted Schezo was the one Arle met at the start of Madou 2: Schezo with a body count, Schezo with minions, Schezo looking to abduct and murder others for the sake of harvesting their magic from them.
This interpretation continues that, thanks to his interactions with the core Madou cast, Schezo eventually overcame the corruption, resulting in the Dark Mage we know now.
Either way, it's a fact that he's not quite the edgey boy he used to be, and is aware of that fact.
He is still interested in becoming powerful, but is significantly less inclined to taking power by force, preferring to instead earn or win it.
But more than that, what he really wants is a life of peace and quiet. He will never get it.
And even more than that, he wants to keep close to Arle, Rulue, Witch, and (to an extent) Satan.
He once admitted to Arle that he needs her in his life. Arle just assumed he was trying to say "I want your power" again.
Perhaps he is scared of succumbing to corruption again in their abscence?
Schezo's preferred habitat is cave.
The cave in Primp Town that he's squatting in is one that used to be frequented by Klug (as seen in Fever 1). It's full of crystals that can be used for magic.
Despite living in a cave, he's still able to cook and bake as he feels a need to. How he manages it is an excellent question.
He adores cuteness and cute critters, but tries to not let it show around others. Acorn frogs, onion pixies, Carbuncle (sometimes), fish-mode Salde, palm-sized elephants, and Amitie's hat (with or without its power) are known subjects that endear him.
He and Witch are close, especially after Schezo saved her grandmother. And then declined to steal her magic immediately afterwords because of her weakened state.
They tend to bicker and/or try to exploit each other when they do bump into each other, however.
Schezo is analytical and observant, able to get accurate reads on people he spends time around when he cares to. It was he that figured out Ringo's fear of ghosts had nothing to do with them being "unscientific."
He also has powerful magic sensing ability, able to accurately detect how much magic power someone or something has on sight.
He can also determine the source of ongoing magical effects, if he's familiar with said sources.
He is able to communicate telepathically with the Dark Sword, though how often they communicate is unknown.
He's only ever silly as a means to an end. Anything beyond that is either an accident or concentrated sarcasm. Usually he has no patience for shenanigans, especially from other people.
He's not very patient about being around other people in general. This is a result of both introversion and social awkwardness (he does not know how to respond to positive interaction in the slightest).
The most likely of the regular cast to complain about the damn kids today (without being one of the damn kids himself).
