NINJA GAIDEN 4 - F.B.N.G. Mission Designer: The Fiend Slayer

One thing I really like about frenzied enemies is that generally the most interesting traits and behavior an enemy has is active all the time. Really brings out the unique flavor of the enemies. DDO Shuriken and the Wind Tengu are good examples of this. The DDO Shuriken's dash attacks become incapable of being stopped with normal attacks, so he's allowed to control space more in a way you have to respect. They also just queue into attacks faster, so they're just flipping and dipping way more often overall. Wind Tengu benefit from the projectile buff all projectile based enemies receive (they fire off projectiles significantly faster), so they really can just litter the field with projectiles if left alone for too long.
