Haagross (hag-RO-ss) is a dual-type Poison/Electric Pokémon.

It evolves from Hagoop starting at level 45.

Haagross has a Nuclear-type variant.

Pokédex Entry[]

Pokédex entry
The slime covering its body is toxic and corrosive. Between that and its electric bite, it has no known predators. They proliferate in contaminated areas.

Biology[]

Physiology[]

Haagross is a large, eel-like Pokemon with a dark purple body that is marked with yellow stripes on the back and a pair of lighting-bolt shaped antennas. Its feet and tail are covered in green slime.

Special Abilities[]

Haagross produces a slime that is not only toxic, but is highly corrosive as well. It can also generate electricity and use that ability to electrocute opponents via a bite. Because of these traits, Haagross lacks any predator.
