@ReadItNow: i do think Doctor Who would win.But i got an question my bro and i had an conversation about this one and we cant agree.Can the Screwdriver just desactive the armor of DV and he would just die?

The light saber has a longer range than the sonic Screwdriver. So it's more about the weapon... But I'd do think Who would win, just would need to travel to the right time :)
