Super Hero Taisen Z

Sneak Brother Younger was part of an army of resurrected (mostly Super Sentai) monsters led by Space RaiderIcon-crosswiki after the revival of MadouIcon-crosswiki Demon King PsychoIcon-crosswiki. They proceeded to attack the gathering of Kamen RidersIcon-crosswiki and Super Sentai, giving them a hard time. Younger helped beat Kamen Rider OOOIcon-crosswiki with Rhino Doubler, Ayakashi Chinomanako and Action Commander Stargull. The heroes of recent years were in a pinch until the arrival of a force of Sentai and Rider reinforcements led by Akarenger and Kamen Rider IchigoIcon-crosswiki. The combined forces of superheroes were able to turn the tide against the Madou army, with Younger being beaten back by OOO. They lined up and used their various finisher attacks to destroy the revived monsters. Kamen Rider × Super Sentai × Space Sheriff: Super Hero Taisen Z

  • Elder's motif is the one of a sea urchin, while Younger and Sister's motif is the one of a turtle.
  • The voice actors of the original Sneak Brothers duo show significance associated with other franchises associated with Toei:
    • In their adaptation of the pirate manga One Piece, Shigeru Chiba portrays Buggy the Clown and Nobuhiro Hiyama portrayed Galdino, also known as Mr. 3 of Baroque Works. The two ultimately join together within the same pirate crew.
    • In the Pretty Cure franchise, both appear as key villains within the Yes! Pretty Cure 5 series: Hiyama portrays Girinma of the group Nightmare, the first enemy faced by the Cures in the original YPC5, while Chiba portrays the Chairman of the villain group Eternal, the final villain of the sequel series, Yes! Pretty Cure 5 GoGo!
  • Sister is technically the only female Action Commander.
  • None of the Sneak Brothers or Sister are one of many Action Commanders that was adapted for Power Rangers Super Megaforce.
  • The reason Sneak Brothers wasn’t adapted for Power Rangers Super Megaforce due to Nickelodeon’s 22 episode limit.
  • The reason Sneak Sister wasn’t adapted for Power Rangers Super Megaforce was due to her coming from a movie that came from an unadapted Space Sheriff movie.
