How to Beat Airbuster in Final Fantasy VII Rebirth (FF7)

Use Key Cards to Dispose of Airbuster components
By using Key Cards on the 3 Consoles spread out in the Assembly facility, you can cripple the Airbuster’s movements, damage output and ammunition. We strongly recommend removing the weapon components, AI Programming Cores or Big Bombers instead of getting items.
Where to Find Key Cards
You can find Key Cards in the facility rooms with the consoles. These are all before the battle itself, so make sure you pick them up before you challenge the Airbuster.
Stagger it with Thunder
No matter the phase, Airbuster is weak to Thunder and can be Staggered by it. You only have few openings to go full power, so try to Stagger it as much as you can.

Avoid the Lightning Mines
Airbuster will spread out a couple of Lightning Mines. These will be on the ground for a little while before unleashing a lightning field that will stun you, so you have the time to avoid them and definitely should!
Once it’s got you stunned, it will fire Big Bomber at you. Depending on your level and difficulty, this can deal 1000 damage, so avoid the mines and rob him of easy targets.
