"Once a project to impress the Worm Queen turned researching assistant to Dr. Tengus and a one-up against Tyl Regor, Dr. Vay Ata'grak is among some of the Grineer's most cunning scientists and prolific killers. Her 'test subjects' undergo cruel and unusual experiments - few are able to escape her grasp, even fewer able to outrun her Elytrok, swarming drones that pester and trip over targets to prepare them for capture. Her studies in the effects on Kuva enabled the Grineer to further evolve."

"Operator, please take caution. Vay Ata'grak has kidnapped and tortured countless innocent lives.
If the same happened to you? I don't know what I'd do.
Please, be safe."
- Ordis, pre-battle

TL;DR: Dr. Vay Ata'grak is a collosal 'next-gen' Kuva Guardian and assistant to Dr. Tengus. Her batch was created after the Worm Queen realized how fragile Kuva Guardians are against the Tenno - modified to their fullest extent, only a handful survived. Vay Ata'grak was one of these individuals. Both her and Tengus are involved in the shenanigans Vay Hek's pulling in the background while we're busy dealing with Fortuna. Needless to say, the bunch take things a bit too far and the Tenno need to intervene.

Personality-wise, she's extremely loud and hammy not too unlike her Hotdog Dad and Screaming Dad, but has a degree of brains to her brawn, though her behaviors more in line to that of Sargas Ruk's than that of Tyl's. Like many of her kin, Vay Ata'grak exhudes extreme pride for the Twin Queens, likewise for her creators.

She's got this whole quest thing going on that introduces her boss fight among other things, hinting towards a battle with Dr. Tengus himself. I've got quite a bit drafted for her boss fight, but I'm not quite certain on how it'll go - there's a companion piece I've got going that'll have info on that.

Combat-wise, she's a hulking beast of a Grineer - slower than other Kuva Guardians, but hits harder while deploying her Elytrok to annoy the piss out of players.

Drops from the fight include a large sum of Kuva and parts for a new Warframe, probably.

NGL I threw her here because I knew 100% that putting her on my main would make for an endless awkward conversation. It's as fitting to canon as a four-year WARFRAME veteran can make it be, but the Grineer are kinky motherfuckers and I like being better safe than sorry, yknow?

Hope y'all looking for thos secksi chunky chicks understand, likewise for those wandering around looking for dank WARFRAME concepts and coming across a chunkfucker making a genuine concept for the memes. It'll be back to your regularly scheduled content here shortly.
