The Legend of the Dragonflame Highschool Collection (US)

Smash up the vending machine outside the restaurant in the shrimp and crab shopping district and it will start to fight back?! Once it is destroyed police will appear. Dont attempt with low defense or health however as police can deal high damage by shooting you. I defeated him easily by spamming the whirlwind kick (jump + press Y in midair)

This is a hidden boss found in Dragonflame 2
