DR FOO is a time travelling alien. Always smartly dressed, sometimes dinner attire, and even with scarf depending how cold it is, Dr Foo is the first female in a long line of travelling Doctors and pretty much looks gorgeous in whatever she chooses. Glasses complete the look.
Dr Foo began to time travel at an early age, as early as she can remember being alive at least, and comes from a long line of time travellers. So long, in fact, she no longer really knows where her ‘present’ is, and tends to live for the here and now wherever her Y.A.R.I.S. takes her. Generally considered to be a ‘good’ doctor, Dr Foo often tries to correct history when required, normally with disastrous results.
INTRODUCE YOURSELF AT THE START OF THE GAME BY READING THIS
My name is Dr Foo. I’m a time traveller from another universe who has hopped back in time just a little too late to save engineer Snotty. Yes I could wind back a few hours and try again, but then I’d probably run into myself, and there are all sorts of time-space continuum things I’d probably destroy. I’m interested in the plans from a historical point of view but other than that, regrettably Dah Fader and his associates will take over the galaxy with the information in those plans. In this universe in any case.
