So, I figured I might as well talk about the OC I would ship with Luigi / Mr. L
Her name is Seaker, she's a dragonoid that can take on a human form (which is her default) and she serves under Queen Cardinal (another Mario OC) as a steward, so you might wanna look up a steward's role in a monarchy.
She has short-ish pink hair, amber-yellow eyes, and wears a red dress with white sleeves. She has short purple horns that poke out from under her hair, and dark purple wings
She uses a Steampunk-esque gauntlet with a built-in grappling hook as well as other functions
I hope this made a semi-clear picture for you, and sorry if I rambled, I like talking about my characters
