The Collector clicked its mandibles as it listened to the fighter known as Kui while simultaneously working out the mechanics of this technique known as the 'Moon Grasp'. The fighter specimen was speaking about how to develop full usage of the Moon Grasp, a specimen required a high level of predictive insight, and indeed, that was certainly true.
To control how another moved using the grip alone, one needed to know how their foe would move beforehand so as to adjust the grip to accommodate for it. Yet, this did not explain how the fighter specimen could affect the Collector's body to such a large degree through a simple and small point of contact like the grip alone.
