Bret M. Herholz is serializing a Doctor Who comic on his Patreon — but you don’t have to pay to read it! Just subscribe. If you do pay, you get access to the pages earlier. He’s up to page 8 now, page 10 for subscribers.
“The Twinning Dilemma” (previously “Cosmic Collision”, which is also a cool title) is written by Lee Shackleford, and in it, the First Doctor (William Hartnell) meets Dr. Who from the 60s films (Peter Cushing). Print copies will only be available at the Long Island Doctor Who Convention in August, or to Patreon subscribers.
(This kind of Doctor-meets-Doctor with different attitudes and influences is one of the things I love about the show.)
