Part 2: The continuation from my last post.
As promised, here the second part.
-The Decade gang, Tackle, and Hina encounter each other and then meet up with Joe and Doc.
-Include Gosei Knight in the fight between the Goseigers and Decade.
-Leave the Gokai Red vs. Decade scene alone as it is a symbolic fight scene.
-Ryoutarou and Hana should be aboard Den-Liner with the rest of the Den-O gang, including Sieg.
-Show a scene of Marvelous attacking Den Liner from the inside.
-Have "Akaranger" say, "I've been expecting you to come and meet me here." Which indicates that it's really Marvelous disguised as Akaranger.
-The sudden death scene should also include, Kaixa, IXA, and Accel on the riders' side and Dragon Ranger's ghost, Mega Silver, and Deka Break.
-Extend Marvelous and Tsukasa's final duel to show a wicked Samurai stance at the end.
-Then reveal the Shocker/Zangyack Alliance to attack and betray their leaders by having the real "Great Leader" and the Black Cross Fuhrer (Kurojuuji-Ou) shaking hands and revealing their plans to destroy their respective worlds to recreate in their images.
-Also they should reveal that Kaitou was an inside man to lure everyone into a setup just to see if Gokai Red and Marvelous played their roles quite well.
-Show the Big Machine afterwards as a last resort.
-In the dimensional drift, it should show Marvelous and Tsukasa meeting the other "dead" heroes including Joe, Luka, Ahim, Gai, and Eiji. Kaitou is not present because he was brought back to "life" and the fact that he made a deal with the Great Leader.
-A mysterious voice, namely "The voice of God" (The same mysterious voice from the end of Gokaiger vs. Gavan) tells the heroes that it's not over.
-Then have the heroes be brought back to life for the epic Hero vs. Villian showdown, but at Enetron City where the Go-Busters are re-acquainted with all of the 35 Super Sentais. Where as all of the riders, including the extra riders encounter Fourze in the Desert to prevent the reinforcements from entering Enetron City. Meteor reappears from the dimensional drift a little confused but understands the situation.
-As the Sentais deal with the main forces, the riders would appears and then over power their enemies.
-The Black Cross Fuhrer and the Great Leader are combined and the Rock Great Black Cross Castle as the fuse together the Gigant Horse and Crisis Fortress into the Big Machine, but only to be betrayed by Kaitou and Burajira as they claim it for themselves.
-Then rest...well the same, except that now the Gokaigers team up with Bioman to take on Walz Gil, Akudos Gil and Rider Hunter Silva and then in the Giant Battle, the Gokaigers use the OOO Rider Keys to Unlock the actual Grand Power of OOO, Namely a new form for Gokai-Oh, Gokai-OOO (Gokai-Oh in the form of the TaToBa combo) and SaGouJyuJin (GouJyuJin with SaGouZo's Arms and the SaGouZo insignia in the chest).
-The attacks are similar to TaToBa and SaGouZo's finishers.
-At space, Go-Buster-Oh Rocket States should be in orange as Fourze is seeing pilot Youko's cockpit with Youko in the back guiding him. Burajira should be in his giant form, but is taken down by Buster Herucles as Beet and Stag Buster are seen at the last minute to save their comrades then Meteor is seen piloting in J's cockpit as summons his limit break on Burajira, while Go-Buster-Oh RS does the Sentai Rider Space Kick on the Big Machine.
-The ending should show the Riders and Sentais encounter each other in a face-off and then have Kamen Rider Ichi-gou and Akaranger shaking hands to symbolize the Rider/Sentai friendship with Amazon in the background saying "Super Sentai....friend!" as he does his sign of friendship and then have Fourze and Red-Buster do the Handshake of friendship as the Post-Decade-era Riders and the Gosei/Gokai/Go-Busters gang encountering each other. The elder generations of superheroes congratulate the younger heroes as tell them to continue on fighting the sake of hope, peace, love, courage, and justice in their own ways, even if they come from different worlds, they still share the same goals.
-Fourze and Red-Buster do their poses as the conclude the film by saying, "Our hearts are one!"
-The Post-Credit scene should have Narutaki surviving the battle as he is revealed to be Doctor G. As he sees Tsukasa and Kaitou bidding their farewell, he does his usual "Onore....DIKEEDO!!!" and vanishes as two shadowy figures in the form of Ika Devil and what appears to be evil versions of Space Ironmen Kyodain are seen in the background of the dimensional doors. Which indicates that there will be a sequel.
That's it.
