Maybe you should change to title to Characters that won't be playable?
Because it's easy to say what characters will not be in at all (That'd be non-video game characters & characters not owned by Nintendo that don't have a big history with Nintendo or were never on a Nintendo console). But the Nintendo characters could appear in some form whether that's an assist trophy, stage hazard, trophy, etc.
Though I think the fact you said "too big" (Because seriously I'm not even that sure Ridley is in the game and I'M tired of that argument) for Ridley either makes you either a troll or someone who doesn't understand that there is ability for characters to be scaled up or down if their normal selves are too huge or too small (Olimar) to get in the game yet.
