The Story of the Defeated Monster
Waking from a 300 year sleep and hoping to finally eat humans again, this creature was loitering around in the mountains when it met 6 black suits.
Though they looked pretty differing from the humans it had seen before, figuring he could still eat them the creature attacked. But his luck had run out.
Wary that they might be captured, the humans attacked with weapons he had never seen.
Before he could even grasp what was happening he was bombarded with bullets, bombs and missiles and put to sleep for good.
All is well and all is good.
