Pastoria City Pokémon Gym Leader: Crasher Wake
The Torrential Masked Master!
The Pastoria Gym is a large indoor swimming pool with numerous floating platforms. Switches on the floor of the pool raise and lower the water between three levels. To get to the Gym Leader, the switches must be hit in a certain order so that a path will be formed with the floating platforms.
In Pokémon Platinum, before heading into the Gym, the player is challenged by Barry.
The Pastoria Gym debuted in Cream of the Croagunk Crop!, where Ash tried to challenge the Gym, but Crasher Wake told him that he was going to be one of the judges at the Pastoria Croagunk Festival, and thus couldn't accept Ash's challenge at the moment.
The Gym reappeared in A Crasher Course in Power!, where Ash faced Crasher Wake in a 3-on-3 battle, which culminated in Ash's Buizel facing off against Wake's powerhouse, Floatzel. Buizel was eventually able to defeat its evolved form, earning Ash the Fen Badge.
Like most Water-type Gyms in the anime, the Gym's battlefield is featured as a pool with several floating platforms on it for non-swimming Pokémon.
The first Pokémon used by Crasher Wake during the Gym battle against Ash was his Gyarados which went up against Pikachu. Gyarados showed its strength by standing up to Pikachu's Thunderbolt, but was defeated when Pikachu combined the speed it picked up by falling alongside a Volt Tackle.
Crasher Wake used Quagsire as his second Pokémon during his Gym battle against Ash, and it proved itself to be very tricky, able to counteract Turtwig's high speed with its excellent hearing and as Quagsire had attacks perfectly suited to battle Grass-types, Ash was forced to recall it.
Quagsire next went up against Buizel and although Quagsire was able to absorb Buizel's SonicBooms with its bulky body, it was knocked out by the sheer force of Ice Aqua Jet.
Floatzel is Crasher Wake's main Pokémon. He was introduced right after Ash's Buizel got into a fight with Pikachu. Upon seeing his evolved form, Buizel became hyped up for battle and a chance to prove himself to Ash.
Floatzel seems to know many different defensive techniques to guard himself from attacks such as inflating the flotation sac around his body and blocking with his fin. He also knows a variety of different and powerful moves. Crasher Wake claimed that Floatzel is powerful enough to endure even a Giga Impact by using his flotation sac. At one point he used his flotation sac to reflect Buizel's Water Pulse back at him, confusing him. Later in the battle he used Ice Fang to freeze part of Pikachu's back. Despite all this, he lost to Buizel after Buizel fired a Water Pulse attack at him which sent him crashing into the ceiling and getting knocked out.
The Pastoria Gym first appeared in A Skuffle with Skorupi, where Platinum entered the Gym in order to challenge it. However, since her only Pokémon were Empoleon and Ponyta, a Sailor working as a Gym Trainer suggested she'd try to catch some new Pokémon at the Great Marsh before challenging the Gym.
Although she failed to catch a single new Pokémon at the Great Marsh, Platinum nevertheless challenged the Gym in Crafty Carnivine and Floatzel and Jetsam, using her Empoleon and Diamond's borrowed Tru against Crasher Wake's Floatzel and Quagsire. With some clever thinking and good timing, Platinum was able to defeat the Gym Leader and earn herself a Fen Badge.
Floatzel was the first Pokémon sent against Platinum. Since his opponent was Empoleon, a Water-type, he proposed, and Platinum agreed, that the battle take place in the pool. After the initial part was just a struggle, with hits and bites from both parts, they then jumped into the water to demonstrate their speed underwater. Following an extremely fast chase, Empoleon was able to hit Floatzel with her Vacuum Wave, sending him flying away, knocking him out.
Quagsire was the second and last Pokémon chosen by Wake. Upon being released, he delivered a powerful Blizzard to Empoleon, to which the Emperor Pokémon responded with the same attack. The cluster of both snowstorms eventually caused Empoleon to hold back and faint. Then she sent Diamond's Tru. After what looked a silent and dull battle, Quagsire showed his skills as a wrestler, taking the Torterra (and lifting it, despite his height and weight) and threw him to the water. However, what he didn't notice (and was ready knock Torterra with a Blizzard) was that Platinum had her Great Marsh overalls attached to Tru's spikes, and therefore was thrown too. Upon noticing it, Wake send his Sailors to rescue her, but just the overalls was underwater. With this, the Water Fish Pokémon didn't shoot the Blizzard and was finished off with a Giga Drain.
