His mother is a Chozo and his father human - Lusamine and Darach are his half-siblings.
He’s, like, eight feet tall and a Pokémon magnet. His height is also why his “labcoat” looks so strange; it’s cobbled together from whatever materials he could get his hands on, usually curtains. (It’s also hard to sew when you’re a giant, hence the rather scruffy stitching. But it does its job!)
His height and physiology is also why his hands and wrists are covered with scars; no gloves will fit him, and he has no idea how to make some himself.
He’s fluent in Galarian (English) and Chozo, and calls Grimsley “Nightingale” in Chozo!
His first Pokémon is the Porygon seen here - it was a gift from his mother.
He’s absolute pants at battling, and kind of lets his Pokémon do whatever they want in battle. (He jokingly refers to himself as a walking first aid kit. XD)
He eventually meets Samus, and they immediately consider each other kin.
Very intelligent, but a bit lacking in social skills.
Wears a device that disguises his half-human heritage when out during the day, but eventually develops the courage to start walking around without it.
Is very warm and soft because of his feathers.
Although the Chozo genes dominate, his human half shows itself in more subtle ways. (E.g. barely visible pupils, which Chozo don’t have, and slimmer shoulders.)
Would love to try surfing with Grimsley, but he is unfortunately too big, can’t swim, and would sink like a rock because of his feathers.
Loves plants and gardening!
He does have ears - they’re just hidden beneath his head feathers!
There’s more stuff I have in mind for this AU, but I’ll stop chattering for now - this post is getting long! XD
