When the Second's corpse was found by the Third, his hands were missing.
The Third assumed this was a calculated insult. In the old days, thieves had their hands chopped off as punishment. And All for One had always been under the delusion that the younger brother he kept in his vault was his property.
While the Third died, the young vigilante he'd picked as his successor hid in a tree and watched. Afterward, All for One removed the Third's ears and placed them inside a freezer. Hikage Shinomori remembered how the Third's ears had gotten smaller and more delicate after he'd received One for All. Not unlike how the Second's hands had softened and his fingers lengthened. Hikage touched his hair, which had turned snow white the day he'd inherited One for All.
The implications terrified Hikage so much that he spent the next two decades hiding in the forest. All for One never managed to kill Hikage. But he found the corpse in time to retrieve the snowy white hair.
Banjo's nose looked a little too small on his face. His successor, En, used to tease him about it. Banjo only laughed and told En to just wait and see what changed for him.
After Banjo's death, En stared down at his toes. He would swear that they'd grown longer.
Nana had a beautiful smile. Toshinori loved that about her. He hated how All for One had ripped her mouth out of her dead body.
Toshinori staggered away from the battle where he'd mistakenly believed he'd killed All for One. But he was missing a few things. He'd lost several internal organs and part of his stomach, including his bellybutton which had changed from an innie to an outie after he'd inherited One for All.
Izuku always had green eyes. He'd gotten them from his mother. After he ate All Might's hair, his pupils slowly turned white over the course of several months. One day All Might looked at Izuku and paled. When Izuku asked why, All Might refused to explain. He just kept muttering that it was lucky someone named All for One was dead.
Then All for One was suddenly not dead. At Kamino, All for One turned his head toward Izuku as if the sightless villain could still see. Then he laughed like a madman and ran away.
All Might was clearly very worried. He said he was working around the clock to find All for One. Nezu assigned a teacher to accompany Izuku whenever he left U.A. But Izuku was snatched straight from his bed at the U.A. dorms.
Izuku woke up strapped to a laboratory table. Nomu floated in tanks around him. He knew where he must be and tried not to feel afraid.
On the table next to him was the careful preserved corpse of the First One for All user, looking exactly as he had in Izuku's vision. The First seemed as if he'd merely fallen asleep. Izuku only felt confident the man was dead because of the stiches all over his hands, feet, and face. The grotesquely empty eye sockets made Izuku jerk his gaze away.
"You're awake." All for One loomed over Izuku, holding a laser scalpel. "Normally I would do this after you were dead, but I need the eyes to be fresh." His grin looked demented on his scarred face. "You're the very last piece I need."
