Suggested by Sonic This is one case where the type advantage will not be enough to win. Voltorb does have some good thunder techniques but Magikarp has his evolved mega form. In that form the size difference is absolutely crazy and Voltorb loses out on the battle of raw strength. He’s just not going to be able to generate enough electricity to win and has no way to block the more powerful blasts like the Hyper Beam. That’s why he will fall here. Magikarp wins.
