Cole Uchiha: Voldemort, do you also want to dance?
Voldemort: Avada Kedavra!

(The author probably wrote it because he was short of books. He is a new author and may not be able to write well. If you don't like it, please don't hurt me.)
(Also, the author is still in school and updates may be a little slow.)
Another point is that the protagonist is a Gryffindor, and it is not a purely cool story to first transform from a weak chicken to a strong one. If you don't like it, don't come in.
