Chocolate the teddy bear

There was a talking teddy bear named Chocolate who was all the colors of the rainbow.
He murdered heretics, this teddy.
In reality, he was a space marine, trained from a young age to combat all heretics.
The teddy realizes that he serves a corrupt and rogue sect of the marines.
Chocolate woke up. He seemed to need something. Something primal. So he went down to the Café. When he was nearing the door he tripped and fell head-first into a bin. As he tried to get out he cut his nipple on a broken bottle, blood streamed up his face and into his little plastic eyes. So he slayed a horrified teddy bear (a heretic, to be sure) and used his cotton to fashion a bandage for his bleeding nipple, and continued  out the door.
