Doctor Who Flux: 14 Best Easter Eggs You Might've Missed
1. The Flux, Anti-Matter, And Omega
The mention of anti-matter in The Vanquishers likely caused long-term Who fans' ears to perk up, because this is a concept that's existed in the show for a long time.
Anti-matter - which we now know the Flux is made of - has roots all the way back in 1973's multi-Doctor romp, The Three Doctors. In that episode, Time Lord founder Omega is actually trapped in an anti-matter universe, so he's likely quite well-informed on the, uh, matter.
This connection raises an interesting possibility: maybe all this talk of anti-matter in The Vanquishers was a hint towards Omega's involvement, and perhaps he helped the Division engineer the Flux in the first place? That mention of "the Master" at the end of the episode felt really on-the-nose, almost like it was a misdirect to mask the real big bad.
Interestingly, Omega was briefly seen in The Timeless Children (that's him, on the far-left of the image below), so he's clearly on Chibnall's mind!
Anti-matter has been used in other ways too. In the Fourth Doctor serial Planet Of Evil, there's a horrifying monster called the Anti-matter Creature, which utterly destroys everything it comes into contact with - just like the Flux does.
To put it succinctly... anti-matter bad.
