The Moderato is a oarfish. It only appears in Super Darius II game.
Looking a bit undead, Moderato ambles onto the screen. His chief attack right now is a three-bullet arc. I think he can be hit anywhere on his body but at the moment he doesn't show much of himself to you. The thing to do is to blow his crest off bit by bit, and he then gets a bit friskier. He brings his whole self out onto the screen now, firing the same bullet arc and a homing missile. Moderato will indulge in Driosawm-like antiques now, twisting himself around (and he can crash into you, watch out). When I took him down, I found myself surrounded by him and hy poor Silver Hawk didn't know which way to point.
