Douluo Wuhun Kyogre

He was drowned by the sea in his previous life, but in this life he awakened Kyogre, the god of the sea in Pokémon. When he woke up at the age of six, he was just a little red fish blowing bubbles, and everyone laughed. Later, a heavy rain came and the martial soul evolved, and they realized that this was not a fish, but a god. (The protagonist is a native of the Pokémon world and traveled to the Douluo world. He is not a modern person, so he does not know the plot of Douluo. This book does not contradict others)
