The Pokemon League is the organisation that runs the Gyms and the Scarlet Conference, a tournament held each Summer of the strongest trainers. In order to compete, a trainer requires the eight badges from either the Gyms of Hoenn or, ideally, the Gyms of the Scarlet Isles. There is no Elite Four to speak of, and the Champion is simply the most recent winner of the overall tournament.
The Gyms of the Scarlet Isles are prestigious. While in other regions, Leaders typically go easier on trainers with fewer badges, so their last Gym challenge is their hardest. There is no such trend in the Scarlet Isles, whose Gyms are exclusively out of the way and challenge the trainers physically just in reaching them. With such a reputation, the Gym Leaders are basically celebrities, and many of them have exposure deals with the Neon Broadcasting Network. As a result, those with more lucrative deals tend to play up their 'character' more, to make the most of their celebrity status. The Gym Challenges are filmed and frequently broadcast. Trainers are often paid a little for making the challenge (which are pre-arranged - the Leader does not simply wait around).
Guerilla Gym:The Guerilla Gym lurks in the Ostermarshes, and is entirely outdoors, exploiting the natural boggy terrain of the area. The leader, Marius, makes use of the terrain to ambush and attack while defended, with Pokemon well-equipped to deal with the marshes. He is gruff and rugged, and once got second place in the Scarlet Conference.
Lost Gym:Probably the single most difficult Gym to find, beyond the Gym of Heroes, hidden in a clearing in the middle of Veil Forest, with an interior and exterior that are literally built into the jungle. Lissa battles with forest-friendly Pokemon and is the eldest Gym Leader. Despite being one of the hardest to get to, she is probably the friendliest and most sympathetic leader and the one most likely to go easy on trainers (possibly following the hard slog getting to face her). As an older woman, she has little demographic value and has no real contract with the Neon Broadcasting Network.
Fury Gym:The Fury Gym is either the hardest or the easiest Gym for most trainers. It takes place on a pontoon just off the Scarlet Conference stadium and in the surrounding water. An artificial bowl filled with water (a net held in place by a firm frame) is underneath the pontoon enabling aquatic Pokemon to battle freely. All of Tomtom's Pokemon fight exclusively in the water, making him an impossible challenge for trainers whose Pokemon cannot swim well or snipe them out. However, he is the least skilled or motivated trainer among the Gym Leaders and cannot give constant commands to his underwater team, so those trainers equipped to deal with him should find him a pushover.
Blue Sky Gym:The Blue Sky Gym is located on the Western peak of Mount Triumph, in a stadium that is taller than it has floor-space. Well-suited, then, for Bryson's flying Pokemon. It is a Gym of similar, but less extreme, difficulty variance to the Fury Gym. Bryson was in the army for a short period before becoming a full-tile Pokemon trainer, but this is his unique character trait among the leaders and an element of his history that he embellishes hugely as, basically, a PR strategy. However, he is also a boisterous man that can't take anything seriously, so the resultant character comes across as rebellious. He is possibly, as a result, the most popular Gym Leader.
Despair Gym:The Despair Gym is located in the centre of the Ruins of Castille and is only open at night. Maria is another hugely popular Gym Leader whose defining trait, in much the same way as Bryson, is her perceived 'Gothicness'. Of course, she is never any less than media-friendly and is, in her spare time, a glamour model and pinup. Obviously. Hers is possibly the easiest Gym to get to, simply being at the centre of a tourist hotspot.
Silent Gym:The Silent Gym is to be taken literally. The dojo, hidden within the Deep Caverns, is barely lit and is designed, almost like a recording studio, to muffle sound, making communication between trainer and Pokemon difficult. Lin tests for inate understanding between battlers and will happily give her badge to those who lose but battle well - and deny the badge to those who do not, even if they win. She is the only critic of NeonCorp among the Gym Leaders and refuses all sponsorship from them, not for lack of trying. Prior to becoming a Gym Leader, Lin was a serial Champion of the Scarlet Conference and Pokemon Leagues around the world.
Wilderness Gym:There is no Wilderness Gym. There is simply a Gym Leader. Ray literally tours the wilds in the north of the Northern Isle, travelling in whatever direction he feels like in no set pattern. Trainers must simply find him and defeat him to win the badge. Some people find him instantly, whereas others have searched for days with no avail. He is, after Tomtom, probably the most easily-defeated Leader. This is the only Gym challenge that a trainer does not have to (and, indeed, can't) book in advance.
Gym of Heroes:Located in the epic Fortress of the Sea, trainers must sail from the Southern Island, entirely under their own steam, to the Fortress, battle through the booby traps and insanely violent, powerful wild Pokemon, and eventually reach the Throne room, where Samuel resides. This is unabashedly the most difficult Gym in every shape and form. Samuel is considered a legend in the Scarlet Isles and was once a huge critic of NeonCorp, but his public voice was one day made suddenly quiet. Despite being one of the more popular Gym Leaders, he makes the fewest public appearances in his capacity as celebrity, after Lin.
Scarlet Conference:The Scarlet Conference takes place in a custom-built stadium equidistant between Kiros Mansion, Port Newhaven and Southport. The tournament is the single biggest yearly event in the Scarlet Isles, both in terms of tickets sold and televisions viewed.
