In the fanfiction world, if Snape was deaged to 16 by a potion, he might have a whole new set of challenges. Firstly, his relationships would change. He'd probably have a different dynamic with his peers at Hogwarts. His knowledge and skills would still be there, but his physical and emotional state would be that of a 16 - year - old. He might struggle to be taken seriously by those who knew him as an adult, and his interactions with students could become more complex as he'd be closer in age to them.
His personality would likely become more impulsive. As a 16 - year - old, Snape wouldn't have the self - control he developed over the years. He might be quicker to anger and less guarded in his emotions.
In deaged Snape fanfiction, the theme of redemption can be quite prominent. It gives Snape a chance to rewrite some of his past actions or at least be seen in a new light. There's also the theme of identity crisis. He's not the same old Snape, and he has to figure out where he fits now. Additionally, the theme of adaptation is common. He has to adapt to his new physical state, new social situations, and new magical abilities or limitations that come with being deaged.
There's also 'Hermione's Second Childhood with Snape'. It's a unique take on the concept. The story shows how Hermione's deaging affects not only her relationship with Snape but also how she views the wizarding world all over again. The author creates a lot of heart - warming and sometimes tense moments between the two characters as they navigate this strange new situation.
I'm not sure of a specific fanfiction with this exact plot, but you could try searching on popular fanfiction platforms like Archive of Our Own. Use the tags 'Snape', 'deaged', 'Lucius' and '16' to narrow down your search.
One possible plot could be Snape having to re - experience his Hogwarts years at 16. He might struggle with his old memories while also dealing with the current Hogwarts environment.

One interesting deaged Snape and Harry fanfiction could be about Snape being deaged to Harry's age and them having to work together on a special project at Hogwarts. They might start to see each other in a new light, away from their usual teacher - student dynamic.
Maybe Lucius deages Snape out of jealousy. Snape was always a bit of a rival in Voldemort's eyes. In his deaged state, Snape might form unexpected friendships with students at Hogwarts. He could befriend Hermione, for example, who would be intrigued by this strange new version of Snape. Meanwhile, Lucius has to keep his actions a secret from Voldemort, as Voldemort might not be happy with his meddling in Snape's life.
