SpoilerNot so sure if this actually adds depth to Velika's character. It anything it devalues it, as it seems to me that it suggests Matoran can't be eccentric on their own, and that if a Matoran is then the explanation has to be "Oh, the he's really a deity-like figure, because of course Matoran can't be too unique on their own can they."
Otherwise, though, I'm glad this was revealed if only to end the inane epileptic tree arguments about people endlessly claiming their favorite villain was the Great Being, against all logic in the starting point of the speculation topic. That seems the most relevant part, since I doubt Greg will ever continue with the serials. Which I'm perfectly fine with.
Also, I feel like this would explain why he was so smart and only spoke in riddles.
