Don't get hit, play patient, and try not to get frustrated. I've fought Zero for like 70 Marvel seconds before either of us got a solid hit, because that's how you gotta play it. If you focus on going in, you will eat something. It's best to stay out of Buster Range, and out of range of random Lightning > Buster bullshit, and the main goal is to get Zero to block something, then Devil Trigger to retain pressure and start calling assists for teleports and then if that doesn't work, you gotta hit them with the high/lows.
Honestly, I'm not the best at the matchup. I know how to play against zoning Zeros well enough, and the rushdown Zeros tend to be focused on moving forward and not about protecting their dome, but the ones in between... those are the ones I struggle with. I know I let Zero get away with a lot of stuff out of fear, too, but the fear of eating a Buster is too great.
And then if they have Hidden Missiles...
