This mech has a long back story. I am writing this for the Final Vengeance.
Long ago, there was a war against a group of mechs fighting for territory and weapons. The most powerful mech got takin' down by a MUSCLE mech. It had left an everlasting spark of energy that, if touched would create a futuristic SPYBOT. A group of mechs, or Sqaud 6501 had been sent to find this spark. A lot of the mechs died of low oil and energy. But one mech had stumbled across a hole. The hole was very big. Long ago, during the war, a deep pit was dug to hide the energy. The hole was found. A group of elite mechs traveled out into the wilderness to find the humanoid. They explored the pit, hopeing for luck. But they had none. But, when all hope was about to be lost, the energy was bursting and coming towards the humanoid. BAM! a spark of light lit the whole hole! The little humanoind grew stronger and had hidden weaponry and more advanced body parts. It had grown to be 10 ft. 11!!! the way back was a hassle because assault mech were coming out of nowhere! The humanoid had killed them with no damage at all! The group of "good mechs" were finally saved!
Now for the "Humouris" part. Well, as you know, Phipson loves to walk alona at nighttime in his whitey tighties (DUH! it's the cool thing to do...). Anyway, he saw the the SF-5. So running home was his only choice. The "robot" turned out to be kelso in a costume. The real SF-5 was so affended by Kelso's act, He grabbed a little gun he likes to carry and followed Kelso home. There for he was dumed... Thanks! BYE!
