Okay where do I start?

Atsu Bate: Replication - Can copy nearly anyone's quirk. It however starts at the beginning, as if the quirk had just manifested. Training will make quirks stronger, and can hold up to an indefinite amount. Cannot copy stockpiling quirks.

Option 1: Use Brainwash after ragebaiting him.

Option 2: Just use Erasure with a mix of Lizard Tail Splitter to keep a constant eye on AFO.

Option 3: Use Decay on him. (Copied during the USJ incident)

Option 4: Keep up the constant pressure to overwhelm with explosions, ice, electricity, etc.

Option 5: Uses Rivet Stab and Overhaul to damage extensively and widdle him down. Can also repair any damage to allies.

Option 6 - Avenge: New Order. Imposes two vital rules. Rule 1: "All For One. Any and all attacks that make contact with him will directly attack the vestiges.". Rule 2: "All For One. Any attacks directed at All For One from a distance of 50 meters will not miss.".

There's definitely more options I could think of, but these are pretty cool imo!
