For Ai, it would be Eevee. For one, the girl does have a fondness for animals. But despite her child-like appearance she is a grown adult and often times slips in moments of depression when she thinks about her predicament with the Black Organization. Eevee is a friendly and very loyal creature that does adapt well to it's surroundings. And with Ai, she needs those reminders to be a child when needed but to also look at life in a better perspective.

With Romana, it would be an Unown. Seeing as she is a Time Lord a Pokemon with psychic ability would be ideal. But what really makes me think this would workis that with her being involved with time and space, the Unown ldo live in their own dimension. Romana has had past experience in living in another dimension herself so, in my mind, this totally makes sense. ...there is more but my brain is flat-lining.

But there will be sketches later! o/
