Olympia is the Psychic type gym leader of Anistar City in the games X & Y, where she has team of Sigilyph, Slowking & Meowstic, pretty good team overall I must say. Then the gym puzzle to reach Olympia is just walking along a path basically, which is a little boring compared to other puzzles of Kalos gyms. Now, Olympia has one of the better character designs from the Kalos characters, and contributes a little towards the story in Kalos, but definitely not as much as Korrina. Olympia basically takes you to the gem thing in Anistar after you beat her I believe, tells you some stuff, then that cues the final team flare fighting portion of the Kalos games. As well, Olympia marks the last Kalos leader to be took out of my ranking, but in terms of my favorite, it was really a toss up between Olympia & Korrina, so even though I put Olympia at the higher position on the ranking, her and Korrina are pretty well tied for my favorite Kalos leader, so that's why I took them out side by side.
