The once pure hearted human accidentally touches an interdimensional cube and his eyes turn crimson as his being is filled with malice and corrupted by a dark energy as the evil god took complete control over his mind

Dragon: "You must let go of that thing! your not yourself right now!"

Human: "And you are you, to tell me what to do lizard?"

Dragon: "I am a dragon...you foolish pathetic human! and your not yourself right now."

Human: "You got it all wrong, I feel like myself..more than ever before."

As the humans says these words a massive energy bursts off of him and the dragon recoils, a shiver runs down his mighty spine upon hearing the human's resolute words and feeling his power.

Human: "You were always a fool, I will destroy you now." The human raises his hand and conjures up a gamma ray burst and blasts it towards the dragon the sheer force of the blasts tears through dimensions and the dragons eyes widen in surprise as he is blasted through multiple mountain ranges with earthshattering force the dragon then begins to disintegrate as he is filled with existential fear and despair as the gamma-ray burst strikes him with unbearable power and reality warping force
