She would like rule the world!!!
She want to create a paradise.
Her version of a paradise!!!
(Of course, without the consent of the other beings.)
She can enslave other beings with plantifications.
She eats her victims/preys and let the victims/preys regrow/reform back as her plantservants.
They will be transformed to plantservants.
To do this so she used Vore and Reformation.
And that makes paradise in the moment and enjoy it.
