Seeing as I always like to consider the more off beat tracks, part of me wonders if the Tobi Roppo Queen's looking to eliminate is one few would suspect -- Ulti.
- I'm getting a Fishman/Mermaid vibe off of her; got the feeling a number of the Beast Pirates possess some varied ancestry ala Jack, King, and whatever the fuck Kaido really is. Also predicting a lot of ties to the Fishmen and Wano to be revealed as well.
- Her look and demeanor remind me of Dellinger.
- Willing to bet her face mask is covering up some kinda inhuman looking mouth or set of teeth like Jack or her brother due to her bloodline.
- Her hair and everything else also bring to mind this notably weird Yokai that I feel Oda won't pass up the chance to reference -- the Amabie; a rather fishy looking mermaid-like creature with long hair, three legs, endowed with prophetic abilities, and the image of whom can be used as a charm to ward off plague.
And wouldn't you know it, I just recently learned that the Amabie has
somehow become a popular mascot in the fight to combat Covid19, I'd like to think Oda
drew with a face mask as a sorta wink to all this haha.
Ulti the Amabie and Queen the Plague: natural enemies? Did Queen once proposition Ulti only to be threatened with castration? Did Queen reject a love letter of hers upon finding out what lies under the mask?!
Anyways, Ulti representing an Amabie also jibes with one of my top theories about her zoan fruit. Most depictions of the Amabie in art and the anime/manga medium tend to depict it as some beaked Kappa looking creature that brings to mind a Golduck looking fish/bird mish-mash. I've long been expecting Oda to throw at us a Terror Bird Beast Pirate, so Ulti presents the perfect candidate. What's more, I've got a very specific Terror Bird species in mind -- Ancient Duck/Goose Model:
Dromornis Planei aka the THUNDERDUCK aka the DEMON DUCK OF DOOM...no, I didn't make those up. And yes, they actually are thought to belong to the same group as waterfowl such as ducks and geese.
Who knows, watch her have a beak like Kawamatsu and instantly fall in love with him ( or he with her ) or something. You could write an entire Noh play around this shit.
Alternative zoan pick:
the Muder Turkey that is Therizinosaurus aka the Scythe Lizard
