So, it begs the question of where Lux has been all this time.

So,Lux has managed to cross over intoDoctor Who’s primary universe.

However, he doesn’t have a corporeal form at first.

The moonbeam at the beginning of “Lux” is how the episode’s title character enters the fray.

As such, it makes Lux a fearsome villain with incredibly fantastical powers.

Lux’s “Don’t make me laugh!”

catchphrase is inherited from the Mr. Ring-a-Ding cartoon.

Formidable though he is, Lux must replicate whatever is happening if a Mr. Ring-a-Ding film is played.

Plus, he can’t go outside as Mr. Ring-a-Ding - at least at first.

Perhaps most importantly,Lux can draw out the regeneration energy inside the Doctor.

After restraining the Doctor, Lux draws the regeneration energy out and absorbs it.

As he becomes more three-dimensional, the Doctor grows weaker.

Instead of growing more powerful,Lux absorbs more and more of the sun’s light.

Is Lux Really Dead At The End Of Doctor Who Season 15, Episode 2?

Interestingly, that doesn’t seem to be the case, at least not in the traditional sense.

As Belinda points out,Lux now boasts pretty much all the traits of a God.

He becomes at one with the universe, detached from most other desires or concerns.

BELINDA: “So, he’s actually a God now.

THE DOCTOR: “Amen.”

Lux doesn’t die, but he at least stops being a threat.
