Last but not least, the biology !
"About Galloway? Ah yes, my favorite paradoxal patient! At first, I theorized that her unusual shedding of leaves was because of stress and/or fear made prior to being found by our talented new blood, but now, with more testing, I found that it might be from the same thing causing that black gradient on her hands and feet, but it isn't exactly known what said thing is.
Her biology is what makes her really special. Living on Hocotate as a biological Koppaite? Intriguing... It seems to stem from adaptation (and atavisms) in her past generations, yet comes with drawbacks that sets her back physically. And I, the Rescue Corps' faithful doctor, have brought it upon myself to make a list! Hehehe...
Jaws and Digestive System : According to Galloway, her (presumed deceased) mother was a reckless Koppaite who traveled the stars eating anything and everything given to her. Doing this for years at a time allowed her teeth to develop enough to eat harder foods other than just fruit juice.
Her digestive system, on the other hand, adapted to getting nutritious foods that didn't have Piktamin U.
Drawback : Even with this miraculous biological discovery, Galloway's body still has its limits. Even though she can eat foods and metabolize off of foods that don't have Piktamin U, her body doesn't gain the nutrients to grow into a fully functional Koppaite unless she drinks fruit juice. That explains why she is so small..
Hocotatian Reminiscent Eyes and Lungs : Her eyes seem to mimic the squinting look of her Hocotatian friends, like Olimar and Louie. These features seem to come from her paternal ancestry.
The atavisms seem to start here too. According to Galloway, a small colony of her paternal Koppaite bloodline apparently had intermarried with Hocotatians after settling onto Hocotate, adapting to the non-oxygen environment.
Drawback : The drawback for this biological feature is the wheezing. Galloway's lungs can handle the non-oxygen environment, but makes her wheeze audibly with every breath, and unable to run long distances without running out of breath.
As of now, there are no drawbacks to her eyes, other than the fact that they are different than the average Koppaite's eyes.
The real mystery, the oblong ears : The real mystery neither I nor Galloway can explain are her signature oblong ears, with no direct explanation nor drawback. Back to the drawing board with this one...
We might be back to testing to find out what our mystery organism manifesting the black gradient and leaf disappearance is..hehehe..."
