I don't use that joke any more times than I've been given the justified opportunities to do so.
And that keep working!
Also don't forget about two particular harpies.
First is psion god who may blend reality itself, but prefer drunk her's ass off, and second is literally immortal phoenix from legends, nuff said.
And power fantasy is not comparing power levels alone, it's also take form as:
Azy can grab dommy lance and achieve stage of
Super Saiyan Ultimate Dom instantly and you can't do it because you mere peasant.
Berwy got a cool flying interdimensional fortress (I'm betting it also can transform and has a megabeamuuuu as a weapon

) and Champ got dusty fort where impossible to buy some boxes for items storage in voulte (NO, I never let that go!

).
Viv can sexualy assault you in dreams and there is nothing you can do about it. (It's corset is just too damn sexy, impossible to resist).
Autiga is has detachable head (wow!) and probably immortal, also live in cool castle with sexy milfpiress. (OMG just look at that's hips!).
Brint can give superpregnancy to Elthara and no matter how much you transform yourself, you never achieve the same result!

Ryn is da queen, that's it.(I'll probably give domspear to her, if that be possible, just for lulz).
Evergreen is obviously EVIL witch and you totally ok with that whatever you think otherwise.
And kitsunes... oh, kitsunes... no, not gona start it again, there is whole thread for that. In nutshell it's you ether will silently swallow their crap or either silently leave, call'em out is not a option. Also it's seems like "happy family" is too much powerfantasy for Tobs taste and he do everything for ruining it, like fricking steamroller.
And any other adamantinish doms, it's seems like for some writers a mere idea for their precious dommy OC's been topped, no saying to be submissive, to Champ is just too much a powerfantasy. And even when something like this comes up, it's either just onetime, or has a bunch of conditions to prok, or feels like a bone thrown to a dog.
And I don't know why, but for Savin sex with Ogrish and Ivris is taboo. Maybe it's do something with powerfantasy, maybe not and he just troll everyone.
And finally - Cait, what Cait has so good compared to Champ you may ask? Answer is - DA CHARACTER MOTIVATION! Her sister was kidnapped and thrust into some strange portal, the only clue being the activities of the Jerkdolus and his cult, plus Kassira seems to know where did Calla go, so Cait must persuade them while fighting their minions and destroying their plans. And want Camp have in comparison? Big red booba demon say "I claim your soul" and "I will corrupt whole world", pfffff well good luck with that. What bad, in world scale, will happen if Champ just turn around and leave Marches? Kas conquest is destined to fail, too much too powerful being around and they consider this world to be their area of interest and will crush Kassira as soon as she stops amusing them, come to think of it, without Champion's intervention that moment will come much sooner. So what Champ's motivation is? Chasing Kas's dick? Or pure altruism? Weak, very weak.
It feels like it's Cait should be the main character of a separate game that should have been called completely different, but the developers decided that to use the name of CoC will be better for PR, well, and ceep concept with body transformations, but only for purpose as cosmetic.
So taking away Champ's sense of self-importance and motivation as a main character is the best example of "It's not your fucking power fantasy!" bitchslap in player face in loong run.
This may seem like listing grips in a place not meant for that, but please don't take it that way, it's just listing my observations and assumptions.
