How well does the vex stack up against the THE QUANTUM ARCHANGEL  The Quantum Archangel is the human Anjeliqua Whitefriar after becoming one with the Lux Aeterna, the substance that serves as the basic foundation for the Multiverse. This goddess is on par with the Menti Celesti, as said in the novel The Quantum Archangel (obviously), in which this being appears. It was also said that it was capable of commiting multiversal genocide on the Chronovores (The Master planned to fuse with the Lux Aeterna and become a Quantum Archangel himself):  THE QUANTUM ARCHANGEL    [quote]The Master was glad the Doctor was there to witness his apotheosis, but his spurious morality could become so very wearing. ‘I have every idea what I’m doing, Doctor: I am finally taking my rightful place amongst the pantheon of gods. Time? Pain? Death? Eternity? They will be my brothers and my sisters. The Guardians of Time? They will thank me for ridding the multiverse of their bastard children, the Chronovores. The Eternals? Perhaps I can take part in their games, risk everything for a taste of Enlightenment?’[/quote] The Quantum Archangel could destroy the shields of a TARDIS, which tanks supernovae and black holes, in less than a second:  [quote]A rhythmic burbling suddenly filled the room. The Doctor turned from the console. ‘There – I’ve activated the TARDIS force field. It probably won’t last for a fraction of a second against the Quantum Archangel’s powers, but it’s about all I can do at the moment.’[/quote] She could alter history on a whim, change her own doings and give Paul back his invention:  [quote]Some of the threads of reality were obvious, and she had rewoven them easily. But the subtler ones had been beyond her abilities, left as loose ends flailing about, spoiling the perfection of the warp and weft. She had the power, she had the intelligence... but omnipotence eluded her. No, it wasn’t omnipotence, it was omniscience. The sheer calculating power necessary to rewrite creation and balance all the probabilities was beyond her grasp. She needed an ally... something, someone, who could provide the calculations. Who could provide – [/quote] The power of the Lux Aeterna, the power of the Quantum Archangel: [quote]The Doctor elaborated. ‘The Lux Aeterna is the energy lattice that underpins the entire multiverse: not just this universe, but any and every other one that could ever possibly exist. It is infinite power, but without form, without reason. Somehow – thanks to the Master’s ham-handed attempt to access it – it has bonded with Anjeliqua. Her sentience has given form and reason to the Lux Aeterna.’ He flung his arms out. ‘Somewhere – out there! – is a sentient being of unimaginable power. She – it – can split a quasar in two with the merest thought. Create entire new realities fashioned to its whims. Destroy Gallifrey just because it suits it!’ [/quote] The Quantum Archangel could create a Universe for each person in the Universe and she enslaved the Mad Mind of Bophemeral, who wasn't able to be controlled by the Constructors of Destiny, a godlike species that helped the Time Lords to evolve.
