The most powerful pets of the 5 main families in the Pokemon standalone version were Pikachu, Fire-breathing Dragon, Water Arrow Turtle, Frog Flower, and Super Dream. However, if you want to see a more gorgeous pet lineup, I recommend reading the game, Peerless Pet, which is a virtual online game novel. King Kong, Lightning, and Blizzard were the best pets in the book, and the other pets were also very powerful. If you like pets, then this novel will definitely make you unable to put it down. I hope you like my recommendation. Muah ~
