She is the mother to at least two Elder Gods: Shinnok and Cetrion.

I don't really know if the One Being fits in with the lore any more.

Well if you can manipulate time you are pretty much as powerful as you can get. Not sure how one beats someone like that. I guess we'll see on 23rd.

My question is if she'll be playable. Some say every character is gonna be playable, other say final boss won't be etc. Which is it?

The story trailer has the Elder Gods telling Raiden to destory Kronika sand timer to restore the flow of time.

Kronika is not on the leaked roster, and I'm sure the game devs have said she is not playable.

We have absolutely no gameplay of her at all. Cetrion seems OP as hell.... She has Tremor/Jax/sheeva ground pounds, A snare, a freeze, a corrupted shinnok laser, Angel/Devil tekken 2 Air laser, A rock wall like she is yasuo from league of legends and turns into a giant and stomps people as a fatality... Her kit is massive like MK9 Kung lao and Kronika is supposed to be more powerful. I can see her stopping time like alexander from Final fantasy 14 and stomping peoples face in. Another part of me thinks shes gonna be in the background of a stage and not a traditional fight. Or she can be a complete disappointment and easy like Onaga was.

Well, Cetrion may have all those tools but she's not going to have them all at once. There's only so much she'll be able to do with three slots.

If Kronika is unplayable, perhaps she has no such limitation....
