In one of the last levels, you'll encounter an AC that doesn't look like an AC at all. It looks like some sort of Winged-Metal Angel. An angel is the last thing you'll consider it after seeing what it can do. With unheard of power and agility, it can leave opponents devastated. A good hint on beating it is to NOT RUN SHORT ON FUEL. Don't use EO cores, because oncew you run out, you're a sitting duck. He uses swords, so for those who think they're quick enough to dodge it, think again!
