I always imagined a fight between Yoshi and Smaug: (The dragon from Hobbit)
Location of Battle: Laketown on fire
Here's a scenario for this: (This what happens if the black arrow failed to hit Smaug)
"Yoshi unknowingly found himself in Laketown which was on fire and sees a large creature flying around attacking it, Yoshi being curious wondering what that vile beast was. This was the fearsome Smaug, a fierce dragon of terror and destruction, cut to the burning bell tower with Bard and Bain as Bard fires the black arrow unfortunately Smaug manages to dodge said arrow and Bard with Bain jump off the tower as it gets destroyed, with the two cornered by the dragon suddenly a white-green polka dotted object distracts Smaug as he turns around and sees Yoshi with a determined expression as he tells Bard and Bain to escape whom they run off as the green dinosaur now frightened at the dragon's glare as Smaug snarled.
Smaug: "You! you let them escape from my grasp! You will pay for this!"
Yoshi: "Yoshi!" (I saved them! and why is this town on fire!?")
Smaug: "So your name's Yoshi? Then face my fury, my armour is like tenfold shields, my teeth are swords, my claws spears, the shock of my tail a thunderbolt, my wings a hurricane, and my breath DEATH!!!"
Yoshi is shaking and trembling in fear at Smaug's remark as the dragon lets out a roar, suddenly Yoshi balls up his fists and furiously glares at the beastly creature.
Yoshi: "Yoshi..." (So. be. it... i will not go down without a fight and save this town.)
FIGHT!!
Who would win? (sorry about this being so long, might write the fight between Yoshi and Smaug soon?)
