In Chapter 9, the so called beast Samneric saw in earlier chapters and the same so called beast on top of the mountain that Roger, Ralph, and Jack saw is just a dead body of an airman in a parachute (Simon's discovery)... he then untangled the parachute lines...the wind caused the body to move like a puppet

The lord of the flies tells Simon that they cannot escape him, the beast, for it is inside themselves. They are the beast. It also tells him that 'he' is going to have fun, and everyone will kill him.
Simon
Simon is the one who converses with the pig's head, known as the Lord of the Flies, about the nature of the beast. The Lord of the Flies represents the evil and darkness within each individual, which Simon realizes during their conversation.
Simon meets the beast in chapter 8 on page 137.
Simon is the only character who realizes that the beast doesn't exist and that the true beast is within themselves.
Simon discovers that the apelike beast the boys fear is actually the rotting corpse of a dead paratrooper, whose body has become entangled in the rocks and vines on the mountain. This realization causes Simon to understand the true nature of the beast as a manifestation of the boys' own inner darkness and fears.
Simon is an epileptic and during an epileptic fugue he has an internalised conversation with the evil which he knows dwells within us all. He mentally projects this inner beast onto the pig's head on a stick which Jack has left as an offering for the imagined beast.
