The consortium has hired a scientist to do something genetic experimentation. This is not good news for the humans because it involves creating creatures that are part human, part animal and yes, part supernatural. If Doctor Robidoux is successful in his experimentation, it means that the already powerful supernaturals will be unstoppable. It's Wynonna and her team to the rescue.
I have to say that I found Yeti Wars far from compelling. The Consortium is determined to unite all of the supernaturals on the globe but unfortunately they're nearly universally hated for their wealth and their power. Thus far, the consortium has managed to bring everyone into the fold except for the vampires, who are determined to keep their independence. The Consortium decides that the only way to bring the vampires into the fold, is to offer them something they don't have - immortality. HUH? A vampire that's not immortal? I know, what the hell is the point? To that end, The Consortium hires Doctor Robdioux to conduct genetic experiments but what they don't realise is that Robidoux is a double agent and is also working for the vampires.
We are told that Robidoux is a psychopath and that this is why he does wild experiments. I found this to be ableist. Why is it so hard to have someone who is not neuro typical just go about their lives or even be on the hero side? Why must they constantly be framed as evil, or beings to be wary of? Robidoux really doesn't even get any development, he's just some horny, mentally ill guy, doing horrible experiments. He's described as a cross between Frankenstein, Doctor Moreau and Dr. Mengle. Here's the deal, it's fine to say that Robidoux is engaged in horrible experiments but it's not fine to decide to invoke Mengle andtherefore the holocaust to make a point.
Robidoux is not the only character who is described as a psychopath. Maxim, the leader of the consortium also considers Dr. Sasha Tarasov to be a psychopath, albeit less so than Robdioux. Maxim charges Sasha with keeping an eye on Robidoux, getting inside of his head and sleeping with him to get as much information as she possibly can from him. She is nothing but a tool and gets absolutely zero character development. Because Dr. Tarasov also falls on team bad guy, we have yet another example of a person with mental illness as evil.
