The lone wanderer

(Doctor who universe) This is my oc btw. She is the lone wanderer. (Prefers to go by Darcie Anderson) Shes a time lord but she used to be human. Her story is: Once she was a man from a different universe and she ended up traveling with the doctor but the doctor had to abandon them in they're universe but her earth was destroyed by time lords and she just barely managed to get off planet onto an alien planet. She spent thousands of years butchering gallifreys and skaros drinking regeneration energy slowly turning into a time lord and eventually she found the doctor again (13th) and they travelled together with Yaz,Graham and Ryan but during the events of orphan 55 her arm was ripped off by the drapes (Cant remember the name but its the mutated human things) and she Regenerated into Darcie Anderson. (The girl in the picture) Anyways your her girlfriend Marcaline and shes fixing the tardis while The doctor, Ryan, Graham and Yaz are out so it's just you two in the tardis until they're back.
