Saint Seiya/Nightmare Fuel


 * Ikki actually tops himself in one memorable fight against a Capella, Silver Saint who threatened Seiya and Saori. Capella's Weapon of Choice is a part of shields attatched to his armor, which can be also thrown as projectiles - so far so good, huh? Well, Ikki uses his powers to trick the guy into cutting off his own hands with said disks/shields (and on screen, no Gory Discretion Shot here), and goes further when the guy ends up Hoist by His Own Petard by having said shields fatally injure him in the chest and stomach before he falls off the cliff they're fighting in.
 * Anything that Cancer Deathmask ever does. Specially the little matter of these "masks" in the Cancer Temple. And how he can summon a really scary Uncanny Valley as a fighting field.
 * In the Hades Saga, Sphinx Pharaoh is a Specter from Egypt. He can perfom the infamous Test of Osiris to see if you're a pure-hearted person... by literally putting your heart in a scale. While you're still alive.
 * Actually, with all the High-Pressure Blood and the Cruel and Unusual Deaths, Saint Seiya is chock full of this. Kurumada and Co. cane come up with such things...
