Blah237, I just simply copy the sprite and put it into the screen on Paintbrush, which is a bit like Paint on Microsoft. And then I fill the sprite with whatever color I want to put on, and I've got a Latias/Ozzy avatar!
Blah237, I'm thinking of making a Latias/Ozzy Pokemon avatar. Maybe with the eyes green, and making the head/neck part brown... I'm currently searching for a Latias sprite now.
