Hmm... some of this reminds me of when a friend and I were making our own region... the Torren region. the two 'version' legends were based off of Nut and Geb from egyptian mythos. Maybe I'll get around to updating them eventually...

Favorite idea from Torren region: Platypaya + Platypon. The platapus pokemon.

Platypaya: Water
Platypon: Water/Poison (ev.@ level 25)
