We need a straight up Evil Protoframe.
With Stalker currently busy with the hardest job in the universe being a single father, we're kind of missing an antagonistic Warframe. What better than to fix that with a Protoframe, who can have a face for us to hate?
It'd also just make sense, cuz there's no way everyone injected with the Warframe juice would be a good person. Someone would get those powers and get sinister ideas. Some contenders I can see:
Proto Nekros feels like an obvious one with how the hex think about death. They'd be disgusted or horrified with his existence.
Proto Garuda since Garuda currently doesn't have much lore at all and would be the perfect psycho villain.
Proto Nidus could be someone who embraced the infestation fully to the point that he even worried Albrecht.
Proto Ash would be an extremely poerful foil to us, an assassin experienced in using our powers??
Proto Stalker or a Proto Acolyte that has taken parts of other protoframes and helminth'd his own choice of abilities? Could also make for a new version of Stalker that invades us, maybe one that finally actually kicks our ass again.
What do you guys think? Would you be up for an evil Protoframe antagonist?
