Got three gym leaders (one of whom is not doing his job) and an elite four member today! And withing them, two of this universe's bad guys!
Firstly we have Balon Greyjoy, gym leader of the Iron islands who currently is not leading his gym and left Asha in charge, What is he off doing? Well, he's the leader of this universe's version of Team Aqua, because he thinks letting Kyogre go nuts on the world will totally let the Ironborn go back to their pre modern era ways of being badass raiders. Naturally he knows not to say this in public since people would think he's crazy...and arrest him. Balon trains a lot of Water and Dark type Pokemon, with Sharpedo and Poliwrath known to be his signature 'mons.
Also, he's very disappointed in Theon for becoming a Pokemon Coordinator. Though, as some elements of his design suggest, Theon comes by his overly dramatic tendencies honestly...
Margaery Tyrell is one of the two gym leaders of the Reach and is considered one of the toughest due to the defensive abilities of her Grass and Fairy type Pokemon. Sadly this left her easy pickings for Robb stark, who specializes in Ice types and also has Steel types. Margaery LOVES getting to mentor newer trainers and can't wait to meet her pen pal, Sansa, when she comes south as a coordinator soon.
Margaery was the hardest for me to design. I went through a lot of dresses, crop tops, skirts, short shorts...I'm pretty happy with what she's got now, though. Also her hair would not Poke-fy very well so finally I just put it up. Coupled with the ribbons I'm saying she has a dancing-themed gym.
Tyrion Lannister, one of the the Western gym leaders who operates out of Lannisport since his father would rather hang himself than let Tyrion be the gym leader of Casterly Rock. Tyrion is the top fossil studier and reviver in the reigon, something he enjoys rubbing in the faces of his family (except for Jaime and Kevan, since they're nice to him). Tyrion fights with Fire and Ground type Pokemon, though many of them have electric type moves just in case you thought sweeping him with a water type would work. He was one of only two gym leaders to give Robb a real challenge in the South. Tyrion's gym is also his lab, so if you break ANYTHING outside the arenas...gods help you.
Tyrion's main outfit piece is his incredibly spiffy labcoat, reminding the world that he IS a Lannister even if he's not running the family gym.
Tywin Lannister is the final member of the Elite Four, though there are murmurs that Ned Stark is actually stronger than he is these days. Tywin loves his "warlord" motif a little too much, even according to people close to him like Jaime and Cersei. As a Rock and Ground battler, Tywin enjoys turning the battlefield itself against his opponents before CRUSHING them. Tywin also has a secret: he's the leader od this world's Team Magma, though for entirely selfish and prideful reasons. He thinks he can utilize Groudon's powers over the earth and ground and heat to create or find more precious gems, thus enriching the Lannister family and expanding their power...of course, his plans never account for the idea that he, of all people, might not be able to control the mighty Groundon.
I gave Tywin a golden cloak like the one he wears in the books, but made it one more practical for walking about in. Also gave him the traditional way-too-blinged-out Lannister armor.
