Years ago, I tackled a project of creating walking animations for all the major characters of Phantasy Star III. It took quite a long time to rip all the sprites from the game and even more to reassemble them in an animation that closely mimicked their gaming timing, but I eventually finished them all. This animation of Siren walking right was a result of that project.
In the game, Siren actually reuses Wren's sprites, complete with black hair. He also never walks. At the request of another fan, I altered the look of the sprites used in this animation to match Siren's speech portrait. The hair color changed to red and the flesh tones to gray.
