Highlight Lustra Furia at the character selection screen. Hold Up until the card flips over to show his alternate version.
At the character select screen, place the cursor over Lustro Furia and hold up for a second or two until the card flips over to reveal an extra version of the character.
This version has different basic and special attacks, but the same magic attacks as "regular" Lustro Furia. He looks very different, too.
