Luckily for King Karp, the cage he was in was made to be blastproof, and the voltorb explosion did not hurt him as much as it should have. Of course, the cage was not fall-out-of-a-giant-castle-proof, but it did soften the landing a bit. He climbed out of the wreck and swam to the sea, where he saw the Slowking Ship leaving the island. His eyes filled with anger How Dare They let their path of conquest destroy the lives of innocents!
He wondered what had happened to everyone else, and decided to swim back to his underwater home, built under a waterfall. He entered, and saw Azu.
"What happened" Azu asked
"Everything" King Karp sighed "Prepare yourselves, its time for war!"
He watched as the floating ship left the island, and went back to the remains of Slow Village, where he and Azu searched the wreck for survivors, finding only a few Pidgey and Slowpoke whom King must have accidentally left behind.
"where are we" one asked "where is our King?"
"Gone" replied King Karp "Gone on a conquest to destroy the Mainland"
The Pidgey flew away to meet their leader, while the Slowpoke attempted to rebuild. King Karp helped them, and it was done pretty soon, as most of the damage was done to the castle, and the village itself just needed minor repairs. There was no repair for the castle, but the actual village was fixed in a surprisingly short time. King Karp and Azu watched from the hill as the Slowpoke entered their homes again, after all, it was their Tyrannical king who had brought this upon them.
He went back to his undersea cavern, and rang a small bell. As soon as he rang it, twenty Magikarp and two Gyrados surfaced from the water, and a Braviary landed just outside of the cave. "you called?" Bravery asked "what do you need?"
"The Slowpoke King is about to invade the mainland" King Karp said "I need your help to stop him"
"Of course" Braviary said "We will help you"
The Magikarp mounted the Gyrados (Gyrados are flying type so obviously they can fly) and King Karp and Azu climbed onto Braviary, and they began to fly towards the Flying Ship of the Slowking King
