Two weeks ago BBC presented us, the Universe, the greatest assassin, Doom! Doom’s Day. That’s a multi-platform story told over books, comics, audio and more, coming soon in order to celebrate Doctor Who’s 60th anniversary by introducing a brand-new character on a 24-hour pursuit of the Doctor.
As she is just saying us, someone has sent literal Death after Doom. She can only outrun it for 24 hours unless she can find the Doctor to save her. It’s going to be launched later this year and the series will allow all Doctor Who fans to follow Doom. You can find more about it here.
