In direct combat, it’s hard to tell, but in a War of Attrition, and I mean an actual war, Xivu wins 9 times out of 10. The only reason it’s not a 10/10 is because of 1 counter feat where she was actively loosing to the Acume along with Savathune and Oryx. As long as there is a significantly stronger force over the Hive and they can move fast enough, Xivu does not have time to grow. Of course, the forces of the GoW universe are not nearly strong enough to defeat her army, so 9/10 she wins. Now, in Live combat, Kratos might just be her perfect match because this dude is powered by sheer, unadulterated rage, and will continue and continue to fight even if he is overpowered. He is not a runner, so Xivu has the perfect warrior to battle. Even if she does end up losing, she would love it.
