[X] The Protector
I think that the protector comes from a place of feeling superiority over humans, he's the Shepard in his eyes, the guiding light but may not actually be that in the eyes of the people he's protecting. A tyrant can be a great king.
combined with the slight smug undertone i feel like it may give more opportunity to characterise the mc as a person rather than a gimmick, the destroyer to me just sounds like a warlord who sees everyone as either a target or an asset, more equal but less complicated and less caring (in the apathetic about people sense, not the loving mother sense).
since we're essentially going to be gods/godlike beings I think the more complicated route will be more interesting.
To be honest, I don't expect EITHER of them to be any good at interfacing with humans directly or at all concerned with individual human life. I suspect they're both more like... living totems, in terms of a social role.That is exactly why i voted Protector. He does not seem to care about anyone as more than assets to be used. That is far more eldritch horror than military camaraderie.
The Destroyer sounds like it uses humans to hit the enemies of Earth harder, either slowing them by throwing humans between the Emmayda and their escape route or mutating them into monsters.To be honest, I don't expect EITHER of them to be any good at interfacing with humans directly or at all concerned with individual human life.
