Amanda is thinking about how to get a better form for herself when she got a brainwave.
I know i'll have the best attributes of all the best species.
And so with that in mind she made the wish that she would have the form of her choosing. And to be immortal.
And so her legs fused together and became black and scaley while her legs stretched until it was 300 feet long and 9 feet thick with venomous spikes. Her torso lengthened to 15 feet and was ultra musculature gaining 1000 pounds of pure muscle and her breasts grew from 36CC to GG size and as she grows 3 pairs of arms her hair turns into tentacles. Scales go all the way up to her breasts. The last changes to happen was that her eyes turned reptilian, her tongue stretched to 2 feet and forked and fangs grew out pushing her canines out.
She said panting "now the world will know the true power of Amanda Goddess of the World !!!"
