The ultimate iteration of the Heavy Ball. A ball that is too heavy to fly high or far, but it is highly effective if you manage to hit an unsuspecting Pokémon.

The Gigaton Ball can be used to catch Pokémon. It cannot be thrown very far, but is more effective if the Pokémon it's used on hasn't noticed the player with a catch rate modifier of 2.75×. Otherwise, it has a 2.5× modifier.
