What is a good, very aggressive move for Ultimecia in Dissidia 012 Duodecim?

Answer 1

There is no most aggressive one, every attack is good for different purposes. I listed the three best below.

Shockwave pulsar is a really fast attack and you can basically spam it.

Apocalypse has by far the largest vertical range, it is great against aerial players.

The best bravery attack is Knight's Arrow, that's what you should use against enemies most of the time.
