Knuckles the Echidna vs Natsu Dragneel

Description
'Nothing hurts more than punches. When two characters that mainly use melee attacks get angry, let's just say that you wouldn't want to be on their bad side. These two easily angered punchers meet in a battle of pure strength and fiery strength, but who's going to come out alive? Knuckles the Echidna of Sonic the Hedgehog, or Natsu Dragneel, Fairy Tail's top Dragon Slayer.'
