I've got my TrainerSona, Alex (see avi). He's basically me in anime form, his team not only including some of my top favorites but also inspired by things I've actually seen IRL. He's socially awkward but enjoys exploring with his Pokémon, snapping photos of wild Pokémon, and searching for interesting items (fossils, evo stones, etc.) to add to his collection. His grey Eevee (a representative of my cat and based on GSC Shiny Eevee) was a gift from his aunt.
This wasn't my first TrainerSona, however. My
original TrainerSona, whose design I'm pretty sure was a reflection of my
original GaiaOnline avatar (loosely based on Koga from Inuyasha), was primarily a Dark-type trainer. IIRC, his team was based on what I used in Pokémon XD: Umbreon, Glalie and Walrein (which I believed were part Dark at the time, Walrein probably due to its Team Aqua card), Nuzleaf, Mightyena, and I eventually gave him a Mew when I started getting into collecting its cards. In a
very short-lived sprite comic, he used a
legendary griffin Fakemon (art by Arkeis).
My
second TrainerSona, a Gym Leader, was born from my Ice-Monotype team during Gen. IV. This one was loosely based on me visually, and his signature Pokémon was Froslass (my MVP at the time). (Credit to xellaya @DeviantArt for the linked artwork.)
