(Theory) Vel'Koz and the Voidborn that appears in the latest cinematic are Watchers,but not frozen.

Since Vel'koz and the Voidborn in the cinematic look so similair i was thinking that maybe they belong to the same specie of voidborn; Now,i know that multiple times it has been mentioned that all voidborns are different from one another,but since the two creatures look so similar i was considering that maybe,even though each voidborn is unique in their own way,some of them share some similarities with one another that allows them to be divided in species,and this is the case of the Watchers:

The voidborn in the cinematic not only looks a lot like Vel'Koz,but he also appears to be smarter than the other voidborns(just like Vel'Koz),since unlike most voidborns,who just seek to devour using only their powers,he attempts to get his tentacles on a much greater power aka the world runes; So maybe the Watchers are actually a type of voidborn that are distinguishable for their unique eye and their intelligence,also explaining why the Frozen Watchers were able to manipulate the people of the Freljord for so long,or why the bard teaser depicts the Watchers as one eyed beigns,and the single eye would also explain the name "Watcher"

So Vel'koz and the creature in the cinematic are both Watchers,but not Frozen Watchers,as the Frozen Watchers are actually the ancient Watcher Voidborns that invaded runeterra eons ago,exponentially growing in size and acquiring ice powers because of the long time spent in the Freljord.
