What would feel like the start of a normal morning (for once) for Class 1-A ended up on its head when a green portal appears in the classroom, and an old man exits from it. "Izuku, I need your help rescuing Morty. He (bleep)ed with squirrels again."

"Mo-Morty, come here!" "What's wrong?" "Lo-L-Look! Tho-Those assholes read fanfics!" "Oh gosh..." "What you doing he-here? Shouldn't you be doing so-something bet-better with your l-life? Wh-What? Yo-You i-interested in this shit? Yo-You sho-shoouln't, that Scarf dude is the wor-worst writer -burp- of this p-plataform. Co-Come on, burp-go to school or something." Have a nice day.

Rick gets tired of Morty's love of the Vindicators and decides to show him some real power. However, they have an unexpected encounter with an unusual boy with green hair.
