Another weird tactic I’ve seen is the idea that, since Duck Hunt Dog is old, that being old isn’t an issue at all, or because Min-Min isn’t the protag, it isn’t an issue at all to not be. Usually used in tandem with other outliers so that every character can seem to be super likely.
Here’s an example.
Perry the Parasol is unlikely? Why?
A one-off? Dark Pit, Sheik, Min-Min say hi!
No moveset potential? Piranha Plant, R.O.B, Fox are right there?
Not important in its series? Have you missed Jigglypuff being in?
Like, honestly, there’s not a single argument against Perry the Parasol that doesn’t crumble under my Logic
