Devil May Cry -
Once the scene starts getting darker and lightning starts shattering the sounds things will get serious. It'll be a bit hard to dodge some of Vergil's attacks now the quick slashes in particular are hard to dodge. You may need to jump to avoid it. Second is his charged attack in which it acts like Aquila. It's easy to dodge though just move out of the way and you'll remain unharmed since the range is very small.
