What if the Yeti of Nunu, The ursin, Fizz Tribe, Alistar Tribe and Ramus are Vastaya ?
It make sense considering they are a chimeric beings specially voliber, alistar and ramus.
Then the Yeti also speaks . So what if in Nunu's VGU the yeti and him interact well and not just the " Don't make the Yeti angry " type :(
And about fizz, i think he is confirmed vastayan because of this, The Makara Tribe, the Carnevorous Ever-Smiling. Unless its another specie. the only thing that we need now is a confirmation from riot.
So my theory is that there is another vastayan update. updating the left out vastayans and their herald maybe is Ramus/Voli/Nunu's VGU and I think the question mark in the image is the ursine's or maybe the ursins is the khonlui tribe, just a diff name because runeterra is vast and has many language (also volibear = rhinobear i think). Lastly, i think alistar's tribe is the Ottrani Tribe too, just my instict telling me that it is his tribe.
BONUS: Don't argue
specie/tribe because they don't look chimeric to me/no animal features. We also need other species/race in LOL too you know. I'm just stating the obvious that the one's i mentioned above look very vastayan.
EDIT: Yes, Ali and Voli are not vastayan as riot says here but the remaining champs that i have said remains unknown at the moment. Another theory of mine is that, Alistar is a descendant of the vastayasha’rei. because as riot say's vastaya is a gene combine with human and vastayasha’rei and we don't know the descendants of the vastayasha’rei only so its possible. We might never know if Voli is too...
and
specifically). On top of that,
has a unique taunts for when she kills Vastayans
