This AU occurred to me a while ago:
Before Vlad created Dani and his * perfect * clone he had managed to create a clone equal to Danny who could maintain his form but the only difference he had with the real one was his eyes of a golden color and his shy personality, to this Vlad he did not like it at all since he wanted a copy 100% faithful to the original (that sick), he felt so much anger and disappointment that instead of destroying his failed creation he preferred to lock him up, not pay any attention and only visited him when he punished him for no reason apparent.
One day Danny had a confrontation with Vlad in his castle and by mere chance came to the dungeon of the place (yes, he has one ..) and decided to take advantage of the occasion and investigate but when he reached a recondite cell he saw inside and could not believe what they saw his eyes ... I get as I could to this, slowly approached the battered being who was chained to the wall, this seeing Danny began to tremble and cry of fear. The hybrid knelt carefully taking one of his hands and his look was one of great sorrow.
No, he could not describe in words how horrible he felt and only tears rolled down his eyes.
-Vlad, you are the most detestable being on the face of the earth and this I will never forgive you I swear ...
