This is false information. Batman only has 1 divekick, not sure where this random idea of 2 different dive kicks came from.
Also yes Batman has slide, but he doesn't low profile in first startup frames in the slide (that would be nice) he only low profiles way after the slide started already. So it's not like youre going to be point-black next to a MB orb and slide under it, you're going to get hit. You would only slide under something if you were about dash distance away from it before you used slide. Not to mention it's -40 on block, so you dont want to just be throwing slides out
Batman does have a double jump, but his forward double jump doesn't even get over the MB orb? And that's the whole point we were talking about, Batman is stuck behind the orb like anyone else. If you try to double jump over and orb you are just going to float into it because his 2nd jump when he glides forward doesnt cover much distance. Batman does have a double back jump, but why would you ever want to go backwards and give ground to a character that is heavily zoning you? Not to mention if you double back jump and he meter burns his projectile, you're definitely going to get hit and sent full screen, which is the worst spot for Batman to be against Fate.
Every character has MB roll. Yes I'll admit Batman's MB roll can be very good with bat trait, but with that being said this is still an option every character in the cast has and is not unique to Batman so idk why you would make that a talking point in why Batman does better vs Fate than others would like Supergirl, Adam, etc.
Your post was one of the worst in this thread to be honest, I feel like you never even played the Fate vs Batman matchup and you're just saying random things just to say them but it's actually mostly false information and not good advice
