Blue was previously confirmed to appear again in Super Smash Flash 2, as an unlockable character with a different design and new attacks. However, in May 18, 2012, was announced that he would be removed from the roster, along with Blade.
Blue's sword seems to be a flamberg type rapier. Note the hand shield under his right hand. This "Flamberg" somewhat emits fire, much like Blade's own katana, which emits electricity.
