In
Doctor Who stories, it's not unusual for there to be a character who takes on a companion-like role, but who does not, in the end, join the TARDIS crew. Granted, this is often at least partly because they've just died, and many wouldn't make great player characters anyway. But there are some exceptions, who can, if nothing else, give us inspiration for character ideas that fit with the setting.
I'm going to start on the Third Doctor's era shortly after the relevant sourcebook comes out, but that leaves me with a slight gap. So today I'm going to look at four characters from the show's first six seasons who either came close to being actual companions, or are particularly suited for it.

First up, and my only choice from the Hartnell era, is
Jenny, from
The Dalek Invasion of Earth. She's a resistance fighter against the Daleks and their robomen, and, from the dates given on screen, therefore hails from the 2170s, or thereabouts. She appears on my list because the character was seriously considered as an ongoing companion, replacing Susan, who left in that story. In the event, the writers decided they wanted somebody younger, and introduced Vicki in
The Rescue, but it could have been otherwise.
She isn't given a surname, nor do we know how, exactly, she joined the resistance. Unlike the menfolk, she doesn't really do any fighting, although it's hard to imagine that she can't if it comes to it. Her main roles in the resistance are organisational, including such things as manning the communications system. But, given that she's been living in a post-apocalyptic world for ten years, it's also a fair assumption that she has good survival and stealth skills.
