Smaug: Even dragons have weaknesses (Trialbycomics submission #1)

For two hundred years Smaug lived in the ruins of Erebor, hoarding the treasure of the dwarves and keeping it from intruders. One day Smaug encounters a Hobbit on his domains, and because of pride, tells him about his only weakness: a wound on the scales of his chest. The hobbit manages to scape, and he spreads the word about the beast’s weak spot. As the dragon seeks revenge, burning a whole village to the ground, this secret comes to be his downfall, when an archer shots him right on his wounds, provoking his death. If there is one lesson to be learnt from Smaug, is that pride comes before the fall, so underestimating an enemy is always a mistake.
