Notable PersonalitiesThe Pokémon LeagueAs the world's most popular sport, league matches between gym leaders are broadcast to TVs across the region and constitute some of the most popular entertainment. The leaders, Elite Four, and champion of the Pokémon League are region-wide celebrities both in their capacity as battlers and in their "civilian" occupations. As is usually the case with celebrities, fandoms and all their associated vagaries are in full play.
Viola: Leader of the Santalune Gym and professional nature photographer. She's known to be personable and easygoing, causing some to call her the easiest gym leader to face (or, if they're looking for a fight with her fans, the weakest). She specializes in bug-type pokémon.
Clemont: A genius inventor and puzzle master of ambiguous age. The inventions seem to be more of a gimmick than for practical use, as they never seem to get marketed or patented. He specializes in electric types and hosts a popular quiz show from his gym in Prism Tower along with his little sister Bonnie.
Grant: Cyllage City's gym leader and a multidisciplinary athlete. As a handsome, athletic young man with a distinctive sense of fashion (yes, that hairdo is supposed to look like boulders), he's popular among the female audience and something of a "hate him or love him" figure otherwise. He specializes in rock types, and seems especially fond of prehistoric pokémon reanimated from fossils.
Korrina: The maybe youngest and definitely newest gym leader, Korrina took over the Shalour Gym from her grandfather only a year or two ago. She's a consummate rollerblader and martial artist. Specializes in fighting-type pokémon and supposedly spars with them personally.
Ramos: Leader of the Coumarine Gym and gardener. Ramos specializes, predictably, in grass-types and takes his theme a bit farther than the average - the whole gym is built around a massive tree, reputedly grown by the man himself. He has relatively few devoted fans, but a perhaps surprisingly large casual fandom, and you'd be hard pressed to find many who actively dislike the old man.
Valerie: Fairy-type specialist, fashion designer, former model, and leader of the Laverre Gym. Perhaps one of the most controversial leaders next to Grant, as the audience seems torn between her dazzling looks and flamboyance and her frankly kind of creepy attitude. As a case in point, her gym is styled after a doll house inside a hollowed-out tree and Valerie herself is fond of dressing up to resemble a pokémon.
Olympia: The enigmatic leader of Anistar Gym. She specializes in psychic types, speaks in riddles, and appears to have bona fide psychic powers herself. The interior of her gym resembles a starfield in which challengers tend to float freely, and may or may not be larger than the outside. The fandom is divided on whether she's a wicked cool real psychic, a charlatan, or really good with smoke and mirrors.
Wulfric: The burly Snowbelle leader is an ice-type specialist, but known as a passionate caretaker for pokémon of all types. Despite being one of the less notable leaders on quirk alone, his gentle giant image and solid fighting style gain him plenty of fans.
Wikstrom: Styling himself after a medieval knight, Wikstrom is the Elite Four member specializing in steel types. Both his speech and appearance give the impression of being displaced in time, dividing the audience into those who think he's cool and those who think he tries too hard.
Malva: Fashionable, attractive, and well-known for a spitfire attitude, Malva is to the male audience as Grant is to the female. As an Elite Four, she's a master fire-type trainer; outside the battling scene, she's the iconic presenter for holocaster news broadcasts, making her one of the best known trainers Kalos-wide.
Drasna: A dragon master from Sinnoh. She radiates a calm, unruffled attitude and a winning smile at all times, and is considered one of the region's most powerful people, both personally and as a trainer. Outside of her status as an Elite Four, though, little else is known about the Dragon Lady, as her fans nickname her.
Siebold: The Elite Four specializing in water-type pokémon. As a young man with a "handsome and brooding" image, the effects on his popularity are predictable. That aside, he's also a world-renowned chef and considers himself an artist, approaching battles and cuisine alike with a passion second to none.
Diantha: Champion of the Pokémon League and strongest trainer in Kalos. As the champion, she's actually challenged rarely outside of matches against the Elite Four or gym leaders for charity, but when one of her fights is on, the audience rating is staggering. When not being the champion, she is an international film star and close friend of several others on this list.
OtherProfessor Augustine Sycamore: A well-known expert on pokémon and their relationships to people, and good friend of Diantha and Lysandre. Currently in the process of recruiting several young people who've completed primary education to help him catalogue pokémon and their native environments within Kalos.
Lysandre: Founder and head of Lysandre Labs and a famous inventor, Lysandre is credited with massively improving quality of life through his efforts to attain, as he puts it in interviews, "a beautiful world". A close friend of Professor Sycamore, he and Malva may or may not be an item depending on whether you believe the rumor mill.
The Battle Maison: Based in Kiloude City, the Battle Maison presents a venue for sanctioned pokémon battles not directly affiliated with the Pokémon League. It is run privately by four sisters (Nita, Evelyn, Dana, and Morgan) and has a much smaller and more regional, but quite devoted audience, owing in no small part to the sisters marketing themselves as essentially mascots.
