Welcome to the Vindex! Let’s start with the Doctor(s) and the Companions. They’re (more or less) listed in order of appearance and the latter have been split up depending on which era of Doctor Who they belong to — you get the idea. These are only the ones we’ve encountered on Who Back When so far. Please bear in mind that we’re going through all of Doctor Who … ever, so if this list seems incomplete right now, fret not; it’s being added to as we go along.
