For those who missed it. This is something I created years ago. The size was grabbed by measuring images of Oryx when his hand smashed on a guardian and comparing that with an image of when he was smaller, scaling it and duplicating the hunter image on top of each other once properly scaled to get the approximate height. Crota was done the same way. check it out.
That’s oryx in his ascendant realm right? Have you considered what his height would be in the physical plane? When we first “kill” him in the regicide mission, dude looks pretty damn big lol
