Guesswhat-
I was watching Doctor Who last night (yeah mark me as a nerd, sure) and I thought of hat kid. She loses her souls and keeps going, has a spaceship that looks like it shouldn't work scientifically, can't permanently die, and has an item that does almost anything.
Hat Kid...
Is a TIME LORD
Why do you think she has a Time Stop Hat?
The laws of time are hers and they will obey her
