From Death to Protect
The Noumu as it was called was towering over Aizawas battered body ready to give a finishing blow upon the order of his master. Shigaraki has a long vile smirk on his face knowing he had every heros lives in his hands here and with a word he could have them all killed.
"NOMU KILL ERASERH-" Shigaraki yelled before being cut out by a scream louder than his
"NOOOOOOOO" came a gut wretching scream from a green haired boy soaked in water, green and yellow lightning gently dancing off has body getting brighter and brighter, everyone had to shield their eyes from a sudden flash. Standing infront of the boy was a skeletal man with tattered long blonde hair and hollow eyes.
"Stand back my boy I will handle this, I haven't been able to help in so long so allow me to do this one thing"
The skeleton of the man began walking forward with a stride of confidence, slowly growing in muscle and flesh as brief sparks of yellow electricity danced across his body, coming to a full height of 7 feet of muscle. His signature hair and unwavering smile coming back to his form for the first time in years. "Have no fear for I AM HERE" he bellows out in a hearty laugh, standing there in all his pride and strength is All Might, The previous number 1 hero who died saving everyone from a super villain known as All For One.
In a gust of wind the Noumu was no longer over his teacher, or near his class at all, It was no longer in USJ at all being flown out of the cieling by the long dead All Might.
