Hmmm. Kind of a broad answer, but I really like excess and absurdity. And contrast, be it size, power, etc.

A lot of shenanigans...~ ❤️

My ampharos Nimbus!
Big boy who loves being huge~

My articuno Wynne!
Her design was inspired by the rito from botw
Canonically a goddess

My latias Airika
Canonically an alchemist, but she's been in a lot of absurd shenanigans.
(last two pics were drawn by me)

My eevee Platinum and their various forms
Very malleable and adaptable creature
Has an ability I call HyperAdaptability, which can cause them to rapidly change to 'optimally' (usually in a horny way) meet certain stimuli or even others' desires~

Which onesssss

Yessss! It's another thing that can be taken to extreme excess~
Creaking and groaning of expanding muscles beginning to sound more like the groans of metal.

Of course, Amphi tends to get a deeper voice along with the deeper creaking of their muscles. To the point that them moaning is probably deeper than a roar from some eldritch elder god they defeated a few growth-spurts ago~
