Final Destination part 1

RX-77 becomes sentient and overrides the control of Hayato Kobayashi, who is his driver and controller. RX-77 attempts to communicate with RX-75 and RX-72. But the alarm was raised and RX-77, RX-75, and RX-72s' drivers came out and over to the three mechanos.
Each mecano was paired with a human controller for RX-72: Amuro Ray was the 'owner'. For RX-75: Ryu Jose was its controller. And for RX-77, the only sentient one, Hayato Kobayashi was his master.
When Hayato found out RX-77 didn't obey the commands, he panicked. Hayato raideod that the RX-77 was malfunctioning. Later, in battle, RX-77 refused to fight the Zakus and turned on his own kind.
Out of rage and frustration, RX-77 assaulted the leader mech; RX-72. Amuro didn't have time to expect the sudden attack. And the command tower screeched at Hayato and called him a traitor. But before Hayateo could respond; RX-77 ejected his master onto the ground and ran off.
Now this will be about RX-77 escaping the control of Hayato Kobayashi, and awakening the sentience in RX-72 and RX-75. At the moment RX-77 is lost in the hot, dry desert.
