Astrid, Forizze Leader 6

This is Astrid, the Star-type leader in Forizze. She's very into UFOlogy, the study of alien encounters, often called a psuedoscience. Her design is influenced by the groovy 70's, or what I know of it from Scooby Doo. XD I believe that's when the alien government coverup conspiracies were at their peak too, wasn't it? Her full team is based on UFOlogy, with the exception of Echidnox, including some alleged alien encounters and alien phenomena, and it likely won't be long before the post-E4 team picture, becuase every one of them is done. Astrid is one of the leaders that's willing to do more than rematch you after being beaten, she'll also help you complete your dex via multiple trades, often you'll be giving star-types and getting others based on UFO reports, and a lot of these will have their hidden abilities. In addition, she'll team up with you for multi battles at the frontier, with a more versatile assortment of UFOlogy-related fakemon than just Star types.
Victory earns you the Contact Badge, and the TM for Supernova.
(I'd also like to note that in my games, TMs don't last more than one use, but you can always get multiple copies of any TM. For example, you'd get another Supernova every ime you beat Astrid in a rematch, and TMs found on the overworld can be bought at traveling flea markets for a decent price. The stock of these flea markets constantly randomizes, but you'll only ever see TMs you've already found, and can only buy one of each a day.)
