Vesurie is a 26 year old bulbasaur snorlax fusion living in the sonic world. His size DEFINITELY comes from the snorlax in the fusion. He can get fatter with food and plant based methods. He has the powers of a bulbasaur, snorlax, and the elements of poison and nature. Which method he uses to satisfy the snorlax hunger depends on what's going on around him (and or his mood), though both methods at the same time makes him fatten faster.
