Do you think that the lady galra generals +lotor might make up "Anti-Voltron"? It does fit (pink with blue, cat lady with green, lotor with black, etc.).
While I would disagree with your at-a-glance assignments mostly just because we don’t know who’s who yet (and even just going off incredibly cursory details I’d peg Pink Ears as more of a Yellow Paladin than Blue), there is something interesting.
In Voltron Force, Lotor is main antagonist, not Zarkon (who is dead)- and one of the things Lotor sends after Voltron is a series of five robeasts that combine together, called the Predator Robeast.
Cursory googling would tell me that Lotor pulled a similar stunt in Fleet Of Doom, where he combined his personal ship with four robeasts.
Basically there’s a tradition of there being “anti-Voltrons”, and with the exception of another one I didn’t mention (Voltron, The Third Dimension with “Dracotron”) Lotor is usually the person responsible.
Despite Zarkon being an ex-paladin, I can’t see him pulling off a Voltron of his own to face the original: first, he’s so fixated on reclaiming “his” Lion, and he also has basically lost any ability to play nicely with others.
But Lotor? Lotor’s a diplomat and I don’t think the fact that he and his generals form a five-person unit is any kind of a coincidence. Furthermore, Lotor seems rather dismissive of Voltron and the promo shows us ships branded in Lotor’s colors challenging the Lions directly- as in, actually going mecha-to-mecha.
I could see Lotor not only having a tentative “anti-Voltron” in terms of pitting Voltron against similar talents and a similar team, but a literal anti-Voltron.
After all, the writers did promise Lotor would have a long game plan and that he’d be up to really cool things.
