>>41706725No it's an alien from outer space not one from another dimension, UBs are always from alternate dimensions, since there's been no comment of Eternatus being from another dimension it can be assumed that it is not an Ultra Beast.
Although tbqh I wouldn't be surprised if, when SwShDX comes out they retcon it to have come from another dimension and from outer space like some shitty fanfiction where they're trying to one-up the previous generations.
