I suppose it makes sense. The thing pushes everything else away from it to cut you deeper. The everything else pushes or shrinks things to make them go faster. 

Defensively, the things make things that hit it go off and away. 

Against Cho and Kamato though, two human sized fighters...

Cho, I'm not so worried. He's made of darkness, can't really die anyway. Kamato? Yes, I am quite worried this won't be an even match up in our favour. Seems like everything that's going to get thrown at us is wildly out of our power zone.
