ok so if the galra truly age very slowly, do you think that gene is present in keith anywhere?? even if it only slows him down by maybe a few years rather than centuries
I think it’s safe to say that Keith carries a fair amount of various alien genes in him, not just Galra. We don’t know much about his past. Personally, I’m leaning toward the Altean/Galran-hybrid-mom theory.
Do the Galra age very slowly because of their Genes, though? If space-time-dilation is a thing in the Voltron universe, their age doesn’t necessarily have anything to do with their DNA! Time passes - to put it simply - “slower” around large gravitational masses. (Occurs when two bodies move relatively to each other.)
