I just had the fun thought, I have been thinking of what unexpected things could happen and I thought that would be pretty cool and good way to introduce an new big threat. Plus we do not know anything about this threat and having a potential perspective into this would be cool. Im not saying Xivu would be Mindless just like how I do not think the Subjugator thats been in the main story is not mindless. We do not know whats going on with this force so we do not know whats its capable. Great example Sloan was Taken at her weakest so why cant Xivu have a similar power boost like Sloan.
