Doctor Who comic subtly revealed the Doctor's true, complex Time Lord name that went largely unnoticed by fans.

Quite a lot, if you’re the Doctor, or Basil, or Theta Sigma, or δ³Σx², or whatever Doctor Who's lead character is really called. Ad. It’s probably not Basil, if we’re honest.

Theta Sigma would assume the mantle of the Doctor and run away from Gallifrey in a broken TARDIS, ... a terrifying reunion with an old friend awaits in Doctor Who's season 15 finale.
