Here, let me flesh it out a bit more.
Easy: Crystal Swordsman: The bipedal man, but with a crystal sword.
Normal: Crystal Giant: Giant form with a gigantic broadsword. Used as a mini-boss.
Hard: Crystal Knight: A large, armored man with an large shield that must be broken before he can be attacked. The shield is completely impervious to small-arms fire.
Dante Must Die: Crystal Dragon: A crystal dragon that can breathe shards of crystals in a gust of wind. When they die, they expand rapidly and explode into a wave of crystals that cause massive damage. Used as a mini-boss.
Heaven or Hell: Crystal Sniper: They stay in their half-moon form and fire small but inaccurate lasers.
Hell or Hell: Crystal Swordsman Redux: The bipedal knight form, but red instead of a dark blue. (It is blue normally, right?)
There. How do you like that, Crazy Demon?
