Ren Akiyama/13 Riders

In an alternate retelling of the series, Ren Akiyama (秋山 蓮) is one of the participants of the Rider Fight known as Kamen Rider Knight (仮面ライダーナイト).

13 Riders
In the 13 Riders TV Special (alternate story), he sees Shinji taking over the Ryuki deck after its last owner dies, and demands the deck be returned, until he sees the list of names. He warns Shinji, but later after setting Shinji up as plotted with the other Riders (in a form of a truce between the Riders) he couldn't bring himself to finish Shinji off, with their friendship developing. In the end, he pushed Ryuki out of the way and took the blow of Kamen Rider Verde's Death Vanish Final Vent. He shook the damage long enough to kill Verde with his Hishouzan Final Vent (similar to how Miyuki Tezuka died in the series, pushing Ryuki out of the way to receive Kamen Rider Ohja's Veno Crash Final Vent). Shortly afterwards, he died in Shinji's arms after giving him the Knight deck, making Shinji Kido the second character to be two separate Riders in the same series.
