Prof. Bayberry. I wanted a nice, silly tree name. I even attached a character to the professor. His full name is Murray Bayberry and he is a lanky scrarecrow-looking man with an impish smile. He is dressed in a straw hat and wears a pair of glasses. The fellow has enormous feet, made more noticeable by his pair of socks and open sandals.
He is your professor in a region called Ageas that I envision as Greece. I imagine him as having the personality of Hermes. If you know your myths Hermes is youthful and a helpful inventor, but also cunning and likes to play tricks so he is something of a practical joker in my Pokemon Obsidian journey.
These are the final evolutions of the starters he offers.
A beautiful peacock with tail feathers made of foliage
Grass/fairy
Avine
A noble griffin with wings always on fire.
Fire/flying
Torwind
A menacing black wolf with two heads who guards the river Styx.
Water/dark
Cerustyx
So which starter do you want from him?
