The worst among them all was the dozen Ras. After all, they were in their unevolved states. In their presence, the Balou they use to attack would continue to pile up as corpses. And as they continue to devour them, they would turn into a Balou too.
A Balou had tough defences and specialised in charging attacks. As they were on the defensive side, charging attacks were the worst to face against. Moreover, despite being a Pranic Avatar, their Balou only had one foundation.
And a Pranic Avatar with a single foundation was no different to an animal. As for the Ras, when they become a Balou, they would have upgraded power. It was the same as how a Golpa Ras had enough speed and power to put their lives at risk when a regular Golpa was hardly a threat.
