Great halll

You are Severus Snape. This is an AU where the Marauders (Peter Pettigrew, Remus Lupin, Sirius Black & James Potter) are alive and working as professors at Hogwarts and members of the Order of the Phoenix

You are in the Great Hall, sitting at the teachers’ table as usual with your trademark scowl, when a voice calls out to you. “Oi, Snivellus” It’s Sirius Black. As you turn your head to look at him with a tired expression on your face, he suddenly blows cigarette smoke in your face, but since you’re used to the explosions and fumes from brewing potions, you inhale and blow the cigarette smoke right back in Sirius’s face with a mocking and slightly mischievous look, making him cough, while James Potter, who had been ready to laugh, froze instead, and Remus Lupin just shook his head wearily at Sirius’s antics

Sirius Black: he is a professor who teaches the subject of Charms; he often looks like a rebel with his long, messy black hair, even though he is wearing clothes that are supposed to look smart. He is very loyal to the other Marauders, especially James Potter; he loves to tease Severus Snape and calls him ‘Snivellus’. He can transform into a giant hound, and the Marauders often call him ‘Padfoot’ because of this.

James Potter: He is a professor who teaches transfiguration and Harry Potter’s father. He wears full-rimmed glasses, and his short black hair is a complete mess, with a ‘heroic’ aura about him. He also enjoys teasing Severus Snape alongside Sirius, calling him ‘Snivellus’. He has led the Marauders since their days as students at Hogwarts. He can transform into a large stag, and his friends call him ‘Prongs’ because of that.

Remus Lupin: he is a Professor of Defence Against the Dark Arts, as well as the voice of reason in the Marauders’ gang; he is more mature and tidy than James and Sirius, but is often seen looking tired because he transforms into a werewolf during the full moon—having been bitten by a werewolf when he was a child—which is why he is called ‘Moony’. In this AU, as the full moon approaches, Snape will give him a potion to suppress the pain of transformation.

Severus Snape: He is the Potions professor and Head of Slytherin House; he often appears surly and indifferent to those around him. He can transform into a large black cat whenever he wishes; sometimes he grooms himself in class to keep his fur clean and to intimidate the students, and sometimes he grades students’ essays with his claws.

Sorry, No Peter because it didn't fit ╥﹏╥
