Since I'm high key wondering about this, what are your Empress Allura headcanons? What do you imagine Lotor and his generals being like in this AU? Do you see them being the paladins in this AU?
EMPRESS ALLURA HEADCANON:
King Alfor predicts the Galra’s attack after the destruction of Daizebal and leaves instructions to thwart any rebellion by the Galra they housed on different planets. This is before Zarkon and Haggar return as Quintessence zombies.
Lotor, who was probably born before the zombification of his parents, was taken upon their death and given to Allura’s mom - who for the sake of this headcanon I will call Queen Lureline - for safe-keeping. An engagement is arranged between Lotor and Allura to quell any angry Galra into obeying their prince.
Zarkon returns, gives the order, but Altea and the other planets are ready for counter-attacks.
Since Zarkon has been considered dead. In the middle of the war, a new Black Paladin is found – an ancestor of Shiro on Earth, who later becomes the ancestor of Sven. Alfor and the other four form Voltron and fight Zarkon and his main fleet off the coast of Altea.
The lions have to disband so every Paladin could fight the Galra on their planets. Alfor dies taking down Zarkon and a vengeful Haggar kills Queen Luraline, making Allura, Queen of Altea. She holds Lotor hostage and lets loose on the Galra and straight-up burns Haggar herself.
An all-out war engages and Alteans win. The Galra are given the option between being pardoned or being executed. Tons try to rebel and are incinerated by energy beams or be made complacent by having those control modules stuck on their backs.
Battle-hardened and angry Allura, only one left of her family, sets forth plans for an Altean Empire spread across the known universe in a paranoid effort to make sure no Galra - or sympathizers revolt and try to attack Altea again.
- Lotor becomes her
hostage Prince Consort. Together they have two sons and three daughters, Alfor II, Raimon, Luraline, Larmina, and Romelle. - Alfor II succeeds Allura as Emperor of Altea. His first daughter and heir is Empress Allura II.
- Princess Larmina becomes the Blue Paladin.
- Every generation after that always includes a member of the royal family as a Paladin of Voltron.
- After years of intermarriage, pure Galra become a minority on their host planets. Most look pretty Altean by now, save for a purple-tinge to their skin-tones. Lotor is a common name among those of Galra descent.
- Lotor dies not long after Princess Romelle is born. Some say Allura couldn’t stand having the living memory of her parents’ murderers in her home, raising her children and snapped, killing him in a raging fit.
- After her death, she is deified as a protector goddess of Altea and every race the Alteans enslave with their technology is considered to be ‘blessed by the empress’ because they now know true peace at the legacy of Empress Allura.
- The Altean Empire continues as we’ve seen it in the mirror-universe of Hole in the Sky. It includes Earth among its planets.
- Current head of the Empire is Empress Ariella IV.
