Well, if I may offer a topic of discussion.
Given how Shantae's main ability is transforming, it's always bothered me that she doesn't have a trademark "Super" form or power-up that outclasses all the rest. Most characters that rely on a wide variety of powers usually have something like that. You know, that one ability that they save for a special moment, and when the bust it out the audience can really tell "**** just got real". Sonic has Super Sonic. Original Megaman didn't really have one, unless you count the combination with Rush, but X definitely did. Kirby has Hypernova Kirby and the Ultra Sword. And so on. The only thing she really has is her Dancer outfit, and I'm not really sure you can call that a power up, it seems rather uh... flimsy.
If Shantae were to gain a super form of her own, what would you like to see in it? A new animal or creature? A recolor of her humanoid form with new powers? What abilities would she have?
Personally, at least as far as looks go, I'd love to see something like the Avatar state from AtlA/LoK, glowing eyes, change in hair color, even though it's become kind of cliche at this point. Or something like Ajna's Heruka transformations from Indivisible, but maybe with not quite such a drastic change. If it had to be a magical creature, maybe a dragon, or a gryphon?
