Eyecon(s) First Obtain: Collecting all 16 (Heisei) Legend Rider Eyecons and have them fused into a single eyecon. Unlike the previous Eyecons, this one allows the use to transform to different forms; the first double-sided eyecon.
1) Heisei Rider
Eyecon Color: Red
Eyecon Code: 45 (Kamen Rider 45th Anniversary)
Transformation Phrase: "Kaigan: Heisei Rider!" ... "Aratana Kousei! Kore wa Heisei!"
Kamen Rider Ghost, Heisei Damashii: This form resembles Ghost's base transient body with red repaints of Grateful armor pieces attached to his body, with each of the face plates (all fifteen plus two extras on the shoulders) marked with the symbols of all 17 main Heisei Riders (from Kuuga to Ghost (center)). His main face resembles a red invert of the Ore face with a new crest attached.
This forms grants the ability to utilize the skills of his 16 predecessors. Whenever a past Heisei Rider's skills is used, their respective symbols glow with a low flame effect while announcing their names (Ghost Driver Sounds). While not shown individually, riders with similar skills are used in a combo, which gives a certain skill upgrade.
* Kuuga + Agito + W = Hand-to-Hand Combat
* Faiz + Kabuto + Drive = Super Speed
* Hibiki + Den-O + OOO + Gaim = Swordsmanship
* Blade + Decade = Card-based Attacks
* Kiva + Fourze + Wizard = Enhanced Agility
( While Ryuki's skill was never used, it should have combo with Decade and Blade, as he's also a card using rider, and the card used in the fight scene resembles the Trick Vent cards in the image boxes, even thought the bases are Rouze and Ride Cards.)
This form's finisher utilizes the power of all the Heisei Riders into a powerful Rider Kick.
2) Kamen Rider (Ichigou)
Eyecon Color: Red
Eyecon Code: Sh (Presumably for Showa)
Transformation Phrase: "Kaigan: Kamen Rider!" ... "Aibou wa Bike! Hissatsu was Kick!"
Kamen Rider Ghost, Kamen Rider Damashii: This form is basically Ghost's default transient body with the Kamen Rider Parka Ghost (which is basically a green hood and a red scarf with red glowing eyes) attached to the head, in which the face plate is basically that of the original Kamen Rider. (Even the henshin process resembles Ichigou's signature henshin pose).
This forms grants most, if not all, of the skills abilities of Kamen Rider Ichigou, adding it to his own strength.
This form's finisher is a nod to the 70s Rider classics: Either a Rider Punch or a Rider Kick.
