After All Might saved Izuku from Sludge,the vial he that was containing Sludge falls from his and landed on Bakugo in an small alleyway. Izuku finds out All Might has a injury hurting him everytime he used his quirk and he's a quirkless as he was but has a power of one for all

Izuku feels the ground rumbling as Mount Lady is running to an emergency. Izuku curious ran to,All Might struggling behind him as he holds his chest in his human form

They reach the site and see Sludge and Bakugo had a fight with him and lost badly as Sludge surrounds Bakugo cutting off his air supply.All the other pro heroes doesn't have the quirks to stop him,Mount Lady tries to get through but is unable

Mount Lady:"Oh no! My one weakness! I need at least a two lane road to get around!"

Izuku's inner dialog: 'It's all my fault,All might used his energy on me. A real hero will come soon.'

Bakugo struggling to breathe manages to plead but it's a muffled "help". With that without thinking Izuku runs at Sludge,no quirk runs directly into danger to save Bakugo.

Blockbuster:"No you idiot you'll get yourself killed!"

Izuku's inner dialog:'What am I doing? Why am I running? Why can't I stop? What would I do? What would a hero do right now?

Izuku throws his backpack at Sludge which hits him in the eye letting Bakugo breathe as his face now exposed. Izuku desperately digs for Bakugo but it's no use

Bakugo:"Ugh what the hell? What are you doing here Deku?"

Izuku:"I don't know. My legs wouldn't stop moving! Bakugo I couldn't just stand there and watch you die!"

Tears stream down Izuku's face

All Might:"I gotta do something but my energy,but I can't!"

Sludge:"Just a few moments you'll be finished kid!"
