"A Legendary could do something like this, or many powerful Pokemon pooling their powers together." By 'this' Sam assumes he means bringing them all here? "As far as how powerful Pokemon are... it depends on the Pokemon. Some are strong enough to go toe-to-toe with a volcano or hurricane, while others can barely fight. As a human, though, I wouldn't want to start a fight with any Pokemon, even a Magikarp." All that flailing and splashing around can leave a bruise.

"I don't know how powerful Blue's Pokemon are, I haven't met them, but Dragonite is one of the most powerful Pokemon out there that's not a Legendary."
