This came to mind and it's not really a fan fiction it's more like a spoof scene I came up with after watching robot chicken star wars. I might make more I got a few ideas but none that are really good. Laugh if you want or just flame. I really don't care just want someone to acknowledge this I guess.
Truth was crawling towards the panel as the Arbiter and Master Chief walked towards him as Arbiter stood over his fragile body.
"Can you see Arbiter...? The moment of salvation...is at hand." Truth said weakly looking up at him.
"It will not last." Arbiter said while grabbing Truth by his neck and taking out his energy sword ready to be ignited through the bastard.
"Your kind...never believed in the promise of the sacred rings..." Truth said still having faith in the lies he created.
Master Chief mumbled, "Believed in yo mama..." He said while fidgeting with his rifle watching the Arbiter grasping Truth in his final moments.
"What was that?" Truth heard him turning his head towards him, as did the Arbiter.
John might as well have fun with him before he dies. "I said yo mama's so fat that grave-mind went DAAAAMMMNNNN!!!" He said while outstretching his arms in an exaggerated tone.
"Oh yeah well yo mama's so ugly she makes the jackals look like Orlando bloom!!" Truth said in an angry tone pointing at him at every syllable.
"Aw, yo mama fight!!" Arbiter yelled out randomly as a bunch of flood host's, Brutes, and Grunts came out of nowhere forming a circle as MC and truth stood in the center with Arbiter in the middle with a chalkboard behind him.
"Yo mama's so stupid every time she see's a elite walk by she says "Oh no the squid rose up from the sea!!"" MC yelled getting up in his face while saying it as the crowd cheered and arbiter made a mark under his name with his energy sword.
"Yo mama's so hairy that the humans mistook her for a Brute!!" Truth shouted back as the crowd cheered on and Arbiter putting a mark under Truth's name.
"Yo mama's so dumb when she saw the grunts she thought they were oompa loompas!!" MC shot back. Another mark as the crowd laughed.
"Oh yeah well yo mama's so stupid... that-that she thought...a energy sword...would keep her active all day!!" The crowd cheered but than stopped after realizing how stupid that was. "Y-you know cuz she thought it was...a energy drink... and they keep you active all day?... well that's how stupid yo mama is.." Truth frantically tried to explain while MC grinned under his helmet and the Arbiter looked at Truth and showed disappointment in his face.
"Yo mama's so stupid that she went isolation to try and make a map that doesn't suck!!" MC raised his arm's in the air as the crowd cheered one of them yelling "The demon wins!!"
The arbiter went up to truth and grabbed him by the neck once more knocking off Truth's crown and ignited his Energy sword. "W-what are you doing? W-WHAT'RE YOU DOING?!" truth yelled frantically as Arbiter impaled him with his energy sword. "GWAHHH!!!" Truth yelled out before dying. He threw his body over the floating platform into the deep abyss of the ark.
Meanwhile...
Truth's body landed at the bottom as grave-mind was under and looked up as he absorbed Truth for information mumbling, "What the hell are they doing up there...?"
