This is actually somewhat false. Bold Move has some really interesting properties. It has a “startup” of 16 frames, and he is considered airborne after the 5th frame. My guess is that during this 16 frame “startup”, he is vulnerable. However, if you use Bold Move and hold back or downback to block and an attack comes within contact before the 5th frame where he becomes airborne, you will still block on the ground. I tested this with Chun’s Kikosho, which is 1 frame after the freeze. I whiffed a standing M right in front of her and held back, which ended up with me being hit. I tried the same thing, but I entered a Bold Move when I saw the super “freeze” animation and I was able to block. Similarly, if I entered the Bold Move early so that Dante was airborne when the super came out, I was unable to block.
Yeah, but your Zero is twenty times better than your Dante. You still do random teleport with Dante and basically just mash on airdash normals. Dante is not Zero, so you can’t expect to have the same level of success when using the same strategy.
Re: Dante vs. Zero, I hate to beat a dead horse, but without assist coverage, Zero’s air approach can’t fuck with Dante. It’s basically about who beats the other guy to the punch, and with how ridiculous Dante’s normals are, there’s really no reason for him to not hit buttons whenever Zero decides to airdash into his effective range. You might be able to bait out a normal with Hienkyaku H, but then I can just whiff cancel to Air Trick to move out of the way.
On the ground, Zero fares a little better. If he’s within range, his standing M will dominate most of Dante’s moveset, but Dante’s crouch M will still outrange it pretty easily, and Dante can just string into a Stinger to combo from there (and Zero simply cannot afford to get hit by Dante). Stand H can beat out crouch M, just don’t whiff it or you’ll get punished. The only problem I see here is that Dante’s ground movement outclasses Zero’s in almost every way. The only way Zero can match it is with Hienkyaku, which, again, needs to be covered by an assist, unless you like to get randomly hit into death. Zero’s ground dashes are ass.
Zero having better mixups/mobility, again, this is all only true if you’re backed by an assist, otherwise Dante pretty much trumps him. It’s really easy to say your character has better mobility and priority when you use assists to cut off avenues of attack and keep yourself safe. Dante can do basically the same thing and is better in other aspects. I give a slight edge to Dante.
