You know how it is. You're a wee fellow and so naturally have a bit of a napoleon complex. What do you do? Perhaps have some form of therapy, to help you try and deal with these troubling thoughts and feelings? Or instead, you could use your magic brain academy as a front for contacting similarly wee, but exponentially more hardy alien solider creatures who seem, like, proper dead keen on war.
So get ready to use your mind and your body, to become a master tactician, but also a fearless and determined warrior. Suit up - the Sontaran empire needs YOU!
