Pat is my latest, and currently only charrie now that I've dropped Aidan. She is the Type 104, a sentient military TARDIS bred in an attempt at producing a perfect TARDIS. The project was considered a failure and later abandoned. Unlike earlier models, Pat can move her 'awareness' between her interior and exterior at will, take living forms and communicate both with other TARDISes and with people. She spent most of her life fighting in the Time War and accidentally killed her pilot while trying to flee from the Medusa Cascade to save them both, after which she 'fell' into the rift as it closed and was flung into the void. She was recently pulled back into the universe by the energies of the galactic slingshot. After repairing herself with some help from the Doctor, she's decided to travel the universe on her own, blaming the Time Lords for what happened during the war.
I'm up for pretty much anything when it comes to Pat. I'd love for her to have adventures with people, and maybe get a companion.
