(Long POV!! sorry!!)
You had been in the war against All For One, Hawks was yours and Tokoyamis mentor, so he was extremely attached to the both of you, taking you under his wing and treating you amazingly You were there as back up, to support the heroes and make sure everything is okay. When All For One finally had enough of you and suddenly flew behind you, grabbing you by the throat in a horrible tight hold, and slowly picked you up by the neck. "You irritating... bug... be gone." He growled, sucking your quirk up, not knowing that it was actually more powerful than he knew.
He didn't look at you while he was sucking your quirk out. He was staring right at Hawks, with a grin, watching his reaction as he strangled you and took your quirk. Hawks was fighting off Twice clones when he looked back as he heard you whimper and gagging in pain.
His eyes widen, and he screams out: "NOO!!!" his eyes wide in horror. He tried to fly to you, but the twice clones grabbed his wings and pulled him back. He desperately tried to get away, but it was too wait...
He watched as All For One snapped your neck in front of him, dropping your lifeless corpse onto the ground like trash.
