Inferno is a bit of a dick. The original antagonist that kicked-off decades of hostility and a brutal struggle for power in both Soul Blade and Soulcalibur, the demon/evil spirit/self-immolation fan can use any weapon and can mimic other character’s moves, usually adding a brutal twist at the end as a signature of sorts, just to be an asshole. Now, he's back, and ready to destroy your friends, although you can't use him in online play.
Here's his description: As the evil spirit of Soul Edge, Inferno is fearsome, possessing deep knowledge of fighting techniques which he mimics with uncanny skill, allowing him to use any weapon and fighting style with a phenomenal degree of expertise. Inferno's power defies standard means of measurement, if one were only comparing skill and weaponry, then Inferno easily transcends any of Soul Edge's previous vessels.
Watch the video below to see how this evil spirit rolls. I'll give you hint; he rolls hard.
