I will make a similar ending in a few minutes with my broken english
He been teleported up to the strange floating square, suddenly a light shines, and something leaves the wall of the platform. An orb with a blue light floats around
"You...hero...of the galaxy, why are you here? Why are you alive? The destruction of your kin should have happended long ago"
The suprised hero stares upon the orb. "What....what is this!?"
"You are....infront of Thalanx, the orb of time and space. I am in control of your destiny"
The hero stares around, there is space around him. The robotic unity and the Organic alliance are fighting all over the galaxy. Survival. The orb speaks once more
"But you are now here....hero of the galaxy. I know of you. I seen you, yes, you have choice in your hand. You can stop this war. Yes, The Robotic Unity only fights agaisnt you Organics to stop you from abusing machinery. I place souls into all AI created...
You have this...traffic light we can call it in your human mind. The Red Light, it will destroy everything in an enormous super nova. You are the destroyer. Fitting for one such as you who taken so much life."
"What....you canno"
The orb flies hastly around him "Do not speak yet, the yellow light gives me control of you. I will call back the armada and I will bring peace in control of your body. But there will be war again in a hundred thousand years, peace never last, the green light will simply drive the Robotic Unity into space, aimlessly, mayhaps they drive into a sun or mayhaps they find another Space Realm to harass"
The hero is chocked, "I cannot do this!"
"You must, else everything is destroyed"
"I can't..."
Come on! Even I can make such an ending.
