  • Height: 270cm
  • Weight: 170kg

The Old Dopant uses Old Creak (オールドクリーク Ōrudo Kurīku), an ooze similar to the Terror Dopant's Terror Field, to age their target. By turning around, the Old Dopant can switch from the rust-colored form they use the Old Creak in to a patina-colored faster form that is geared towards combat.

The main user of the Old Memory was Takashi Soma (相馬 卓 Sōma Takashi), a palm reader in Futo who Shroud gave the Old Memory to in a calculated plan to get rid of Shotaro. As the Old Dopant (オールド・ドーパント Ōrudo Dōpanto), Soma took on the name of the Ager (ふけさせや Fukesaseya), offering to age any person his customer hates for the right price, taking delight in his work. Although Shroud states that only the power of Kamen Rider W CycloneAccel Xtreme can defeat the Old Dopant, Accel holds the Dopant for Double CycloneJoker Xtreme to make a direct hit while in his aging state. When the Old Dopant assumes his fighting mode, Accel uses the Machine Gun Slasher to defeat the Old Dopant.
