The monkey leader was livid when it realized that its troop had suddenly been attacked out of nowhere. It was leisurely enjoying its time sitting on top of the heap of fruit and eating when suddenly a sharp pain was felt on its chest, and the force behind Matthew's claws pushed him off of the stack of red fruit to the ground below.
(A/N: For those wondering, Yes. A group of monkeys is called a troop.)
It was furious at first, but when the alpha monkey didn't see anything or anyone that was responsible for doing that to it, it became confused and afraid instead. So when Matthew suddenly appeared out of nowhere, the alpha monkey was more cautious about its action and decided to slowly back off first and observe the situation.
