The knight Katsuki Bakugo walked into the potion shop of the town he was in. "Hello Potion Seller. I am going into battle, and I want your strongest potions."

The green haired store owner turned away from his stock of colourful bottled wonders to face the Knight. "My potions are too strong for you, Traveller."

Katsuki narrowed his eyes in confusion. "Potion Seller, I tell you I am going into battle, and I want only your strongest potions."

The store owner, Izuku Midoriya, smiled. "You can't handle my potions. They're too strong for you."

Katsuki leaned on the counter. "Potion Seller, listen to me. I want only your strongest potions."

Izuku smirked. "My potions would kill you, Traveller. You cannot handle my potions."

"Potion Seller, enough of these games. I'm going into battle, and I need your strongest potions." Katsuki insisted.

Izuku leaned forward into Katsuki's personal space. "My strongest potions would kill you, Traveller. You can't handle my strongest potions. You better go to a seller that sells weaker potions!" Izuku said with intensity.

Katsuki spoke up, but he seemed to be more… emotional. "Potion Seller. I'm telling you right now, I'm going into battle and I need only your strongest potions."

"You don't know what you ask, Traveller. My strongest potions will kill a dragon, let alone a man! You need a seller, that sells weaker potions!" Izuku shot back. "Because my potions are too strong!"

Katsuki began to tear up. "Potion Seller. I'm telling you I need your strongest potions! I'm going into battle! I'm going to battle and I need your strongest potions!"

Izuku leaned even closer. "YOU CAN'T HANDLE MY STRONGEST POTIONS! NO ONE CAN! MY STRONGEST POTIONS ARE FIT FOR A BEAST LET ALONE A MAN!"

Katsuki began to cry in earnest. "Potion Seller, what do I have to tell you to get your portions? Why won't you trust me with your strongest potions, Potion Seller? I need them if I'm to be successful in the battle!"

"I can't give you my strongest potions because my strongest potions are only for the strongest beings and you are of the weakest!" Izuku said, digging it further into Katsuki's heart.

The Knight took a deep breath and calmed himself. "Well then, that's it, Potion Seller. I'll go elsewhere. I'll go elsewhere for my potions."

"That's what you'd better do."

"I'll go elsewhere for my potions and I'll never come back!"

"Good! You're not welcome here. My potions are for the strongest and clearly you are not of the strongest you are clearly the weakest!"

Katsuki huffed. "You've had your say, Potion Seller, but I'll have mine. You're a rascal. You're a rascal with no respect for knights!" Katsuki wept. "No respect for anything! Except your potions…" He cried out in anguish.

Izuku picked up a potion. "Why respect knights…" He dropped it to the floor and a burst of purple smoke rose up. "… When my potions can do anything that you can?"

The smoke cleared to show a copy of Katsuki, a more powerful copy.
