Another Universe (Teen Wolf X Harry Potter)

In 2011 the Potter family had received a letter telling them that their daughter was never dead and had been found from when she went missing in 1999.

They are later joined in the great hall with the rest of their family and friends to watch her life in Beacon Hills as Violet Martin.

Teen wolf S1-S6B

OCXAllison Argent (s2-3B)
OCXStiles Stilinski (s4-6B)

Allison and Scott never got back together after S1.
Stiles and Malia or Lydia never happened.

Just imagine that Harry and everyone are in their 7th year of Hogwarts in 2011 so he was born in 1994 so that makes Violet the same age as Ginny. Also no Voldemort in this story he was killed the night he tried to kill Harry but instead of 1981 it was in 1995. Everyone is alive including Regulus and Bellatrix and everyone hasn't gone crazy they just don't necessarily get along with Gryffindors.
