Air Clip is a weird character with a complicated history. Rillian was my first pony OC back when I used to RP on the Ponychan boards, Air Clip was my second. He started out as just a teenage colt who struggled with self esteem due to his secret desire to like dressing up like a mare. In the next rendition he was a fully grown stallion who would put on a dress whenever he went out for a night on the town, particularly one certain bar where he met a gooey mare that would change him forever.

In his current state, he is entirely made of slime. Said goo can change in color, transparency, even levels of hardness ranging from free flowing liquid to more solid rubber most commonly. He only is male by default due to being that way when he was still flesh and blood, able to change his form and gender at will, molding his goo as he pleases. He loves to look pretty and make outfits out of himself for both him to wear...and you if he thinks you'll look nice in them~
