Keshoian Venusaur

Keshoian Venusaur are way larger than their Kanto counterpart, but are more peaceful in nature. Keshoian Venusaur absorb all bad toxins in the air, and transform them into breathable, clean oxygen. 

Although it is an environmentally green Pokemon, Keshoian Venusaur are extremely purple due to the absorption of bad toxins. They use some of the absorbed bad toxins in battle!
