When it comes to missing abilities:
Ragna: Memory Manipulation (can erase the memory of someone's dream using his Grimoire)
Hakumen: Resistance to BFR (He resisted Kokonoe's attempt to warp him out at 20% power during his fight with Ragna in Calamity Trigger), can create vaccum like holes from cutting projectiles.
Susano'o: Every ability Hakumen has from the Susano'o Unit, Susano'o also has.
Izanami: BFR (Does so to Hakumen in Chronophantasma's ending), can conjure platforms for her to stand in the air, Teleportation, Immortality Type 5, can create a barrier around her for protection, can create a ring of energy and launch projectiles from it.
Now that I mention Izanami, I found this in the BlazBlue wiki:
"Also in BlazBlue: Centralfiction she claims that it would be difficult for her to create an energy blast like one Corpse Burial: Requiem was supposed to make, which was going to atomize the entire planet and the moon with 10 to the power of 31 joules worth of power, but she made it sound like she was actually capable of that."
What do you guys think?
