He was once defeated by Kamen Rider but survived in the Game World. After Team Ex-Aid as the Goriders destroys the Andor Genesis spaceship, he appears as the boss of the Chou Shocker Taisen (超ショッカー大戦 Chō Shokkā Taisen, Ultra Shocker War) bonus stage of the Chou Super Hero Taisen game. During the final battle, he is ultimately killed when his red-colored Big Moraimarz Robo is destroyed by an enlarged Ex-Aid Maximum Gamer Level 99 with the aid of the Kyurangers' KyurenOh pair and spaceship ORION.

Behind the scenes
Shocker Leader III is portrayed by Diamond✡Yukai. As Oogumo Great Leader, his suit actor is Kazutoshi Yokoyama (横山 一敏 Yokoyama Kazutoshi). In Kamen Rider Drive Saga: Kamen Rider Brain, he is voiced by Tomokazu Seki (関 智一 Seki Tomokazu).
Oogumo Great Leader was designed by Takayuki Takeya (竹谷 隆之 Takeya Takayuki).
- His Spider motif, as well as being shared all the way back to the very first monster, Spider Man, is also shared with the Great Leader's Black Satan incarnation from Kamen Rider Stronger.
- The suit of Oogumo Great Leader's body is recolored from the Super GingaOh in Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max.
- During his appearance, he utters the line "From now on, this is our stage!" (これからは俺たちのステージだ！ Kore kara wa ore-tachi no sutēji da!), which is oddly similar to Kouta Kazuraba's "This is our stage now!" (ここからは俺たちのステージだ！ Koko kara wa ore-tachi no sutēji da!) catchphrase.
- Oogumo Great Leader has Double Riders' "insect wings" design on his back.
