Fire Weakness: His feathers are highly flammable; fire is his primary weakness as it burns them and severely limits his mobility. Damage Sensitivity: Severe injuries, such as the burns sustained from Dabi, can permanently damage his "Quirk Factor," forcing him to rely on prosthetic wings and katanas. 

Limited Quantity: Using too many feathers at once shrinks his wings, impairing his ability to fly. Regeneration Time: If feathers are destroyed, they take approximately two days to fully regrow.

Strength and Versatility: A single feather is strong enough to carry a medium-sized object or a human. Vocal Espionage: By sensing these vibrations, he can remotely decode conversations from a distance.
