Second drawing on Sai, I was... playing C:
Original character, from my anime project: Vengalla.

This is Diego Latrix. His father was one of the most important scientists in an apocalyptical world where humanity is dying because of SEP (Premature Ageing Syndrome -"Sindrome de Envejecimiento Prematuro" in spanish-).

Blah blah blah (no spoiler, guys xDD)...

He can control earth and lightning elements; he hates his father because he never trusted in him, and his best friend/rival betrayed him, so he's... quite unbearable with everyone else... Wouldn't you?

PD: I can't speak English ._. Gomen nasai, minna-san!
