Thinking about my borb anatomy headcanons. Meta Knight's wings can both absorb and dispel heat faster than any other part of his body because of how close the blood vessels are to the skin's surface within the thin membranes. He spreads his wings in the sun when it's nice out. As somebody who is often in close contacts with vultures, I see them doing this all the time. It's called a horaltic pose. If Meta Knight is overheating, spraying some water onto the membranes of his wings and letting it evaporate will cool him off very effectively.

Oh yeah, by the way - in my hcs/au an altered version of the anime were events that took place before the games, so Fumu is depicted as a bit older here and that's why her outfit is different. I also just like drawing alternate outfits for characters. Technically given my hcs Meta Knight should be wearing his old armor design here but I figured it would have been too confusing to people who don't know what I know and it would have taken away from the joke. I felt I could get away with Fumu's design, though. I honestly just wanted to draw it.

(and of course, bounces when he does it)
