Eyecons (眼魂 Aikon) are eyeball-like devices used by the from Kamen Rider Ghost. There are two types of Eyecons, one embodying heroic spirits called Ghost Eyecons (ゴースト眼魂 Gōsuto Aikon, lit. "Ghost Eye Souls"), and the other being sentient Gamma Eyecons (眼魔眼魂 Ganma Aikon, lit. "Eye Devil Eye Souls"). Later, 15 heroic spirits based on their respective historical figures were chosen to be sealed in another type of Eyecons known as Ghost Eyecons; these Eyecons were compatible with a Ghost Driver, allowing one with a Driver to transform and utilize the powers of the heroic spirits.
