I really envy the generation of fans who grew up reading the Magazine Comics of the 90s and early 2000s, the comics I read as a kid were those crappy Adventures magazines and Battles in Time (loved the cards though!), the ones where very little effort was put in to the stories and they were just there to provide the kids with a couple pages of bright colours. Whereas the Magazine Comics, especially during the wilderness years were top tier and one of the earliest home runs was Ground Zero. This culminated a series of quick stories setting up this adventure where Ace is abducted and finds herself on a plain of existence beyond the Doctor's reach along with two of his former companions. Meanwhile the Doctor is reunited with his granddaughter Susan as he's confronted by a member of the Threshold who warns him something hidden inside the human consciousness is about to break loose.

Ground Zero is admittedly a very brisk story, one you could read in about fifteen minutes and the inclusion of Sarah-Jane and Peri doesn't really play that big a role in the story, they could honestly have been any other companion. But it's the striking imagery that really sells this story and the massive cliffhanger to part four. For a comic to kill off a televised companion is probably one of the ballsiest things I've ever seen in Doctor Who, this was back when the expanded media had free reign to take the Seventh Doctor anywhere they wanted and they weren't yet bound by the continuity of the show. It's such a spectacle of a comic story that it's well worth buying the omnibus.
