Not to gang up on you or anything, but she can seriously do a good bit of what Dante can and more.
Examples
- She has two moves that resemble Vergil's Spiral Swords and Sword Storm (the swords spinning around or flying toward a target)
- She has at least one teleport move
- She definitely has a block and a dash-like move
- Her dodge is incredibly useful both in the air and on the ground for cancelling and traversal
- Witch time is basically a prettier version of Quicksilver style. If I'm not mistaken, certain upgrades allow her to use it without dodging first.
- She doesn't have Doppelgänger, but she has an attack where two or three of her shadows attack with a slight lag, much like Zero in Marvel vs. Capcom.
Actually this video pretty faithfully shows off everything she can do.
It's like Devil May Cry 3 gameplay, except more freedom in the air and
a lot more versatile.
