Crisis Fortress (クライス要塞 Kuraisu Yōsai) was the base of the Crisis Empire in their invasion of Earth. It is capable of flight, travel through dimensions, has a tractor beam on the underside, and launch fireballs from its "mouth". Later, during the events of Super Hero Taisen, another rebuilt Crisis Fortress served as the base of a revived Dai-Shocker.

An altered version of the Crisis Fortress, called Super Crisis Fortress (スーパークライス要塞 Sūpā Kuraisu Yōsai) was used by the Dai-Shocker remnants who called themselves Super Shocker. This version can fly and launch fire balls from the mouth, though it has not been demonstrated to travel through dimensions or has a tractor beam like the original. In addition, the Super Crisis Fortresss is able to emit energy bolts from its body, fire energy balls from dozens of launchers across its underside, and use its many legs in combat. It was destroyed by Kamen Rider Double.
The Big Machine (ビッグマシン Biggu Mashin) is the combined mecha formed out of the Crisis Fortress and the Dai-Zangyack base, the Gigant Horse. It was made when the members of Dai-Shocker and Dai-Zangyack secretly united behind Tsukasa Kadoya and Captain Marvelous. It was destroyed by Rocket Drill Go-Buster Oh.
