|Odin is Shiro Kanzaki's personal representative in the Rider War, possessing incredible strength, the ability to teleport around the battlefield, and many powerful Advent Cards such as Time Vent and Survive. Odin's lack of concern towards living left him fearless, which was his most intimidating factor against the other Riders. Aside from his ability to turn back time in conjunction with Kanzaki's abilities using Time Vent, Odin had the ability to traverse time and warp to any location he choose. He appeared proclaiming himself as the "Final, 13th Rider". The identity of Kamen Rider Odin is unknown. When someone transformed using the Odin Card Deck, they were turned into a mindless puppet controlled by Shiro Kanzaki. Odin had three purposes: he could interact with the real world in ways that Shiro Kanzaki (being part of the Mirror World) couldn't, such as using the Time Vent card to turn back the flow of time; He protected the life of Yui Kanzaki at all costs.; And finally, he was Shiro Kanzaki's trump card in the Rider War, created to eliminate the last remaining Rider so that Shiro could ultimately win the Rider War and the coveted wish.
Odin appeared briefly in many episodes, his debut revealed him using the Time Vent card and had time reversed. Shinji was then the only person who appeared to feel the effect of the time change, and tried to alter the course of time which happened. Unfortunately Shiro told him that that cannot happen as the course of time altered in the past would direly affect the future (which obviously would affect the Rider War and its outcomes). The first Odin was a homeless man whom Kanzaki handed the Card Deck to. This Odin was destroyed by Kamen Rider Knight Survive. The second Odin was destroyed by the combined efforts of Ryuki and Knight.
The third and last Odin fought Kamen Rider Knight Survive after Shinji's death. This Odin was destroyed by Kanzaki himself (when Kanzaki realized the pointlessness of the Rider War) before he could use his Final Vent on Kamen Rider Knight Survive. Before fading away, he declared Ren the Final Rider. Kamen Rider Odin made an appearance in the 13 Riders special amongst the Kamen Riders against Kamen Rider Ryuki and Kamen Rider Knight. After Kamen Rider Ryuki was knocked to ground, Kamen Rider Odin grabbed his Card Deck and destroyed it.
