As you inspected your new paws, you noticed your father slowly approach you, his gaze locked to your reptilian eyes as he gripped his sword, it didn't take long for you to understand what he was planning.
"Father, please! I may not look the same, but I'm still the son you raised!" you whimpered, hearing your new voice, being feminine, yet deep.
"Love he... she's right, not all dragons are-" started your mother, who was interrupted by her husband, "SILENCE!" switching his gaze to her, "You know very well that I see no good in those beasts, they are only good when they're slaughtered like dogs, or when their skulls are placed on thrones." he spoke, his voice filled with anger, he then looked at you, "And you... are no longer my son."
That's when you felt like everything around you freeze, what your father just said struck through your heart like a dagger, feelings of hate, sadness and betrayal swirled around your mind, a dark mixture of emotions that awakened something, it wasn't an instinct, it was... a need. A need to destory what the former dragon hadn't, a need to kill both of your parents and take what they had left, a need to kidnap your brother and take him inside a cavern or a forest, a need to lay a clutch of eggs and create more dragons.
Your reptilian snout previously had a look of shock and disbelief, but then it quickly changed into a look of ferocity and rage, your father proceeded to charge towards you, raising the sword high up in the air, trying to slash through your scales, but with a quick swoop, you devoured him, right before your mother, his sword falling to the floor with a loud thud.
You then turned your attention to the queen, your former mother, who was cowering in a corner, "Darling please... it doesn't have to-" she started, you didn't want to hear her beg, so you took a deep breath and exhaled a stream of flames towards her, incinerating her body in an instant.
With a growl you slowly stood up on two feet, letting the rubble of the castle's throne room fall around your feminine, reptilian body, until there was an opening which lead to the outside, you then let out a deafening roar as you took flight, exhaling flames on people, homes and other buildings around the kingdom, the knights who tried to pierce your scales were melted inside their armours, the mages that tried to force you to the ground were either crushed or eaten alive.
In a matter of minutes, you managed to decimate the entire kingdom, after which you returned to the destroyed castle, in order to take what was left of the treasure your former parents had.
While you took various precious gems and golden coins, you heard a human voice, instantly recognizing it as the one of your "brother", with a toothy and sadistic grin, you followed it, and found your former sibling hidding near the rubble of the castle, his eyes widening as he started shaking, "P-Please! Don't eat me!" he begged, you let out a growl as you approached him, starting to think about what you could do with him.
You could either kill him or leave him in the ruins of his kingdom, or maybe, you could take him with you and find a new lair, or just like the former dragon, rape him on the spot, and convince him to join you.
