@Leos Klien I did include in Rebeca's CS a description of what she looks like in her Primal form (essentially a humanized version of Primal Groudon)
"In Primal Form, Rebeca becomes much closer in form to Groudon. Her markings and scars glow with molten heat, her nails transform into claws that have completely overtaken her fingertips and toes, her teeth become completely carnivorous, and she grows to half again her normal size. Her eyes take on the same molten appearance as her markings, and extreme waves of heat radiate off her body, melting or incinerating most nearby objects. Her skin becomes closer to the armoured plates that Groudon possesses. For the love of all that is alive and good, do not put her in this state."
If there is a serious discussion that needs to be had in terms of the affect it has on her, however, I'm always open to it.
