Fire Shark/YMMV


 * Anticlimax Boss: Many of the bosses can become this if you have a level 4 laser or flamethrower weapon. They WILL die VERY quickly.
 * Demonic Spiders: Tanks, when the Dynamic Difficulty gets turned up. They can be likened to the tanks in the Raiden series, a.k.a. "Sniper Tanks"- what with the Improbable Aiming Skills, extremely fast bullets, and firing almost immediately as soon as they appear. For the water equivalent, we have gunboats.
 * In the arcade version, almost all the regular Mooks become like this.
 * Game Breaker: The Flamethrower weapon. At max level, it shoots out 6 streams of fire that sweep almost the whole screen except for directly behind the player character. Not to mention is does massive damage too...
