Rat-tat-tat-tat...
Boom!
Optimus Prime stood in the clearing, and Red Spider provided another round of aerial bombardment from the sky.
Surfboard recovered from the assault, and the severed spiral hand blade fell off, transforming into a hand cannon.
Megatron looked at Optimus Prime raising the hand cannon, loading the ammo:
"There are other energy sources on Earth..."
Optimus Prime burst out from the smoke of the explosion, and Megatron immediately fired in unison with Surfboard!
Boom!
Yet another plasma gun hit Optimus Prime squarely, the continuous bombardment covered him again, leaving him barely able to fight back!
The shelling, gunfire, and explosions left Optimus Prime dazed, and Megatron shot again, sending him flying into a building by the roadside!
"In the end, is the fate of our race no better than the life of one human?"
Megatron, instead of firing again, stepped forward menacingly, viciously questioning Optimus Prime.
