and tank Brahmastras to the face and beat Scathach? i doubt there is enough info available to give any good justification for how Ozy is superior to Cu Alter. hell, i doubt that Ozy is going to get wanked harder than a guy who is supposed to be equal to hercules and Arthur when they are all at their maximum power (and wouldnt being in Brittain give Arthur access to the spear, just as it would give Achilles his armour and Cu his castle?)
heck even base Cu i have i would have difficulty saying that he would just straight out lose to Ozy, Ozy is the guy that specializes in fighting a lot of people at the same time with arguable success in regards to how fast he accomplishes his kills vs Cu who specializes in killing individuals with greater certainty and can take on armies as well
