Zenkaigers are fighting Tojitendo's combat men Kudakku.
They do their role call and the people react and cheer to it.
Kudakku and their lead Kudaiter get defeated. Kudaiter can speak normally.
Ijirude inserts a Tojiru Gear inside a Kudakku to give birth to the main villain of the movie - Super Warumono Warudo.
Super Warumono Warudo uses his ability and summons the past Super Sentai villains who appear in front of the Zenkaiger member separately, attack & kidnap them.
Once kidnapped they are tied in the open place where the Final Battle will take place.
All the past Super Sentai villains + Super Warumono Warudo are standing in front of Zenkaiger. But all Kaito can think of is that they are able to have Pizza - Sukiyaki Party.

That's where the rescue arrives. All the Red Warriors gather and Akarenger says "We will take over from here".
They free Zenkaigers and attack Super Sentai Villains inside a big tornado. Even Zenkaigers are puzzled with what's going on.
Kaito transforms into Zenkaiser and Akarenger reacts with the gag line "You are not Red?"
Kaito claims to become the First Super Sentai to defeat all the Villains
Then there is a scene where's Akarenger's alter-ego Tsuyoshi Kaijou and the Red Sentai sparkling with light. They seem to accept the new Sentai Team → Zenkaiger and pass on the legacy to them. Most probably the final scene of the movie.
