10. He Can Pull Off The Bow-Tie Look
http://www.youtube.com/watch?v=QFy87tFTZwY A shameless appeal to nostalgia perhaps, but a glimpse at this reveals him to be a potentially interesting composite of the Second & Eleventh Doctors, both of whom were fond of a bow tie and a decent catchphrase. Plus he has a certain musical gift, as heard on ' Things Can Only Get Better' as well as the rest of the comparatively unknown D-Ream back catalogue, which could be useful if the situation demands it. And he's not afraid of his status as a pop physicist, so could probably break down any concept, however daunting, with ease to his companions. As his startlingly broad fan appeal shows, he might have no shortage of aspiring companions. Most of whom his IQ could comfortably run rings around as he attempts to solve the problems of the universe by being quite nice and putting an arm around whichever alien nasty's invading that particular week. Which is, of course, an elaborate ruse to stop them cottoning on to the fact he's sussed out their plan and has already worked out how to stop them, but doesn't want to show off before he reveals his gambit, followed by an easy to digest explanation and a cry of 'Amazing!' as he heads back to the TARDIS, waiting for the day he really does get to step out and shake hands with Michael Faraday. If he's lucky, perhaps they'd give him a whole ' The Key To Modern Science' story arc.
