Doctor Who: Series 13 Trailer Breakdown - 20 Things You Must See
10. Galactus Joins The Whoniverse!
Back to the more polished special effects now. One of the trailer's money shots is this image of a dark cloud enveloping a blue planet (Earth?), which surely can't be good news for the people on the surface.
It almost looks like that horrible version of Galactus from Fantastic Four: Rise Of The Silver Surfer, doesn't it? Let's pray that Series 13 isn't as bad as that movie though.
This Doctor Who cloud could be a visual representation of the Flux - perhaps the Flux is a sentient, malevolent force, rather than a timey-wimey event.
Alternatively, the cloud could be that "Swarm" Chibnall referred to when describing the series at Comic-Con. There's a popular theory that "Swarm" is an acronym (S for Sontarans, W and A for Weeping Angels, R for Ravagers, and M for Master), but it could just as easily be its own individual thing.
