Geki Jumonji, the new Gavan, is assigned to investigate a criminal operation being conducted by Mad Gallant, one of the 12 Apostles of the Genmakuu.

Tropes
- Accidental Misnaming: Secretary Sophie calls the Dekarangers the Akibarangers.
- Actor Allusion: The reference to Akibaranger between Sophie and Ban. Ban's actor, Ryuji Sainei, guest starred as both himself and Delusion World version of Ban in Akibaranger.
- Bitch in Sheep's Clothing: The Smile and Gentleness diaper company is really a front for Genmakuu to revive Satan Goth.
- The Cameo: Numerous transformed Sentai and Metal Heroes are glimpsed towards the end as potential candidates to join Space Squad. They include, on the Metal Hero side, the current Space Sheriff Sharivan and Space Sheriff Shaider, Kyojuu Tokusou Juspion, Sekai Ninja Sen Jiraiya, Kidou Keiji Jiban, Draft Redder, Tokusou Robo Janperson, Shou of Blue SWAT, Blue Beet, B-Fighter Kabuto and, on the Sentai side, Denzi Blue & Denzi Green, Yellow Flash & Pink Flash, the Chikyuu Sentai Fiveman, Mega Red & Mega Silver, Ginga Red & the Black Knight.
- Co-Dragons: Mad Gallant has Kuronen and Benikiba. Up until the latter affirms she only answers to Fumein and leaves.
- Converted Fanboy: Bergian Kronen goes from being a hired gun of Mad Gallant to a full fledged Genmakuu loyalist.
- Even Evil Has Standards: Benikiba shows notable disgust at Mad Gallant torturing Shelley. He seems aware of this, as he gets more violent once she leaves.
- Greater-Scope Villain: Guru Fumein is the mentioned as being both Mad Gallant and Benikiba's master.
- Leaning on the Fourth Wall: Secretary Sophie misnames Dekaranger as Akibarangernote , to which Ban spontaneously recites the Akibaranger's catchphrase before regaining his composure and correcting her.
- Legacy Character:
- This movie introduces a new incarnation of Butterfly Ninja Benikiba from Sekai Ninja Sen Jiraiya.
- Mad Gallant turns out to be Lars, who built his armor using pieces of the original Mad Gallant from Kyojuu Tokusou Juspion.
- Legion of Doom: Genmakuu, an alliance of villains from across the Metal Heroes franchise named in homage to the Makuu from Space Sheriff Gavan.
- Mask of Sanity: When Geki first enters Smile and Gentleness, the CEO Lars appears to be a pushover bullied into aiding Mad Gallant. It later turns out that he IS Mad Gallant, and is very much a sociopath.
- Red Herring: Mad Gallant at first seems to be the original resurrected, even having Jyunichi Haruta reprise his role. But it's actually Lars taking up his armor and combat ability.
- Reunion Show: Unites the complete Dekaranger cast who had last assembled in Tokusou Sentai Dekaranger: 10 Years After two years prior.
- Sequel Hook: Though Genmakuu are thwarted here, Benikiba mentions Coolgin, a villain from Chōjinki Metalder, as a fellow Genmakuu member who is currently active.
- Versus Title: The first installment of Space Squad is titled much like Gokaiger vs. Gavan, though there is no conflict between Gavan and the Dekarangers here.
