The key word: PERSONALITY. That’s why I believe Hilda and Impa have way better odds than Skull Kid. He also doesn’t have much unique about him (Majora was the main villain, not him. Without that mask he’s just another pointless side character who can’t really do much.) In fact, Hilda does more in her game than skull kid ever did (Summon Ganon, Steal the triforce, have a misunderstood villain cliché, and shows lots of personality toward the end), and Impa is in several games, usually either as a sheikah warrior or a wise old lady, so there’s a lot to do there. Also, I should probably mention skull kid includes an entire race (I know that we’re only talking about one, but I’m including the race as a whole and I’m just gonna point out they all pretty much do the same thing, the only thing that makes ‘Skull Kid’ different is that he is controlled by the spirit of Majora, and that was only for one game + a spin-off that doesn’t really count toward the canon). This all also heavily applies to Shantae, Personality, unique moves, something she’s known for, and her franchise has no reps to worry about oversaturation.
