Superpowers do not an interesting personality make, and purposefully creating a Mr. Exposition just puts tentanus-flavored icing on a cake that was empty on the inside to begin with.
Only three people are allowed to go to great lengths to verbosely explain how they're going to kick your ass before they kick your ass,
One, torturers, because explaining your methods verbosely is an actual torture method.
Two, Yugioh Characters, because they are fictional characters and thus it is physically impossible to slap them in the face and yell "GET ON WITH IT!"
Three, your opponent in a game of Magic The Gathering, because not only do you need to hear it in order to know how the game is going to progress, but it is socially unacceptable to slap them in the face and yell "GET ON WITH IT!"
Not to mention, when the character takes all that time to explain it, it just comes off as fucking smug and unlikable, even and especially if they explain it as they do it like a pedantic shit. These details are best explained/heavily implied over narration, when they actually become important, and not a moment sooner.
