(Naoto and Tadano throw both of their Wonder Ride Books to Saber, who picks them.)

Saber: Thanks, my friends.

Naoto/Tadano: We're counting on you, Nathan.

(Then Saber prepares to change forms as he removes the current Wonder Ride Books from his driver.)

LION SENKI!

LAMP DO ALANGINA!

(He places the books and the Haouken Xross Saber in his driver before pulling the latter out.)

SEIBA BATTOU! DRA! DRAGON! LION! SENKI! AH! ALANGINA! KIZUNA GA MICHIBIKU SHŌRI NO YAKUSOKU! GAPPEI SHŪPPAN! FEATURING SABER! SANSATSU TOKUSŌBAN!

(Saber becomes Featuring Saber.)

Storious: You think you can stand up to me?

F. Saber: The future is mine to create!

Storious: I see...

(Then Storious summons the Four Sages under his command and turns them into the Lords of Wise.)

(As they are summoned, Storious gives them a command.)

Storious: Get him!

(They charge at Featuring Saber while both Naoto and Tadano prepare to transform as well.)

TATEGAMI HYOUJUUSENKI!

ARABIANA NIGHT!

NAGARE BATTOU!

GEKKOU IKAZUCHI BATTOU!

Tadano/Naoto: Henshin!

TATEGAMI TENKAI! SUBETE O HIKIISHI TATEGAMI! HYOUJUUSENKI! GAO! LONG GET!

GEKKA GA YAMI WO TERASHIDASU, SEN TO HITOTSU NO MONOGATARI! ARABIANA NIGHT! SPARKLE NIGHT!

(They transform as they prepare to fight.)

Blades: I swear on Suiseiken Nagare that I shall protect.... the people that I love!

Espada: My feelings will pierce through.

(They start fighting, but Spartan easily defeats Blades with a few strikes while Espada shoots a lightning slash which Highlander absorbs and performs a more powerful counterattack, hitting Espada and beinging him down while Diago dashes and kicks him continuously. Saber fights Kuon and has a hard time dealing with him, but then prepares his finisher.)

HAOU XROSS SEI RETSUZAN!

(Saber summons the ten Seiken and sends them flying towards Kuon, who deflects his attack and redirects it towards him, bringing him down.)

Blades: (worried) NATHAN!

(Suddenly some portals open up as one of the Kamen Riders jumps out of it.)

Ichigo: RIDER PUNCH!

(Kamen Rider Ichigo punches Spartan as Kamen Rider Super-1 jumps out from another portal.)

Super-1: SUPER RIDER FLASH KICK!

(Super-1 kicks Spartan, destroying him. Suddenly a sound is heard.)

ENGINE MAXIMUM DRIVE!

(Accel comes out from the third portal and slashes Highlander before ZO comes out from the fourth portal.)

ZO: ZO KICK!

(ZO kicks Highlander as Accel speaks up.)

Accel: Despair is your ultimate goal!

(Highlander screams as he explodes, and then Kuuga comes out from the sixth portal and runs towards Diago before jumping off.)

Kuuga: MIGHTY KICK!

(Kuuga kicks Diago, leaving his mark on him as he explodes, and finally Blade comes in from the sixth portal as he prepares his finisher.)

KICK! MACH! THUNDER! LIGHTNING THUNDER!

(Blades dashes at Kuon and kicks him, making him explode.)

Storious: (stern) Who dares interfere with my plans?

????: I do, idiot.

(Then a rainbow colored boy comes in with the Geartlinger.)

Storious: (glares) Who are you?

(A/N: This is Megaforce-Verse's Owen Patrick.)

Owen: You will find out soon!

(Owen then inserts his sentai gear on his Geartlinger and starts spinning.)

Owen: Change Zenkai!

YON-JUU-GO BANG!

BANGBANG! BANGBANG!

(He then pulls the trigger, transforming.)

BA-BANG! BA-BANG! BA-BANG! BA-BANG! BABABABANG! ZENKAIZER!

(He becomes Zankaiser as he introduces himself.)

Zenkaizer: Secret Power! Zenkaizer!

(Then he and Saber start fighting Storious who parries their attacks. Zenkaizer starts shooting with his Geartlinger, dealing a bit of damage. Storious then slashes him before kicking him away.)

Saber: I have an idea!

HAOU XROSS SEI RETSUZAN!

(Saber summons the ten Seiken, which appear surrounded by an image of a galaxy. Dogouken Gekido lodges itself into the ground in front of Saber and forms a shield resembling a turtle's shell made of rocks around itself to block Storious' attack. Saber then wields Onjuuken Suzune and charges it with pink energy while the Seiken is surrounded by shockwaves. Saber swings the sword, launching a string of rainbow energy musical notation toward Storious. Saber next jumps into the air wielding Ankokuken Kurayami and Kougouken Saikou before launching two energy slashes combined into a single x-shaped slash. After the attack strikes Storious, two vortexes of light and darkness form behind the opponent. Fuusouken Hayate appears above Saber, who spins it in front of himself to destroy Storious' attack before throwing it at him. Saber then wields Eneiken Noroshi and covers its blade with smoke. He swings the sword and launches the smoke, which circles around Storious to surround him with smoke. While Luthor is inside the smoke, Jikokuken Kaiji appears above him and and attempts to spear him, crashing into the ground, but Storious dodges. Wielding Suiseiken Nagare and Raimeiken Ikazuchi, Saber runs toward Luthor. He performs a slash of water with Suiseiken Nagare and slash of lightning with Raimeiken Ikazuchi, followed by simultaneous slashes with both swords. Finally, Saber uses Kaenken Rekka and the Haouken Xross Saber to block Storious' attack. The emblems of the two Seiken glow before Saber performs a blue and purple energy slash surrounded by multicolored sparkles with the Haouken Xross Saber and a fire slash with Kaenken Rekka to Storious' attack.)

(Zenkaizer gets up and pulls out a Wonder Ride Book.)

Zenkaizer: Saber! Catch this!

(He throws the book to Saber, who catches it.)

SUPER HERO SENKI!

JIDAI O KOETE TATAKAI TSUZUKERU HERO-TACHI NO MONOGATARI. HERO WA IROASENAI, HERO WA EIEN'NARI.

(Then Saber places it on his Seiken Swordriver and prepares to transform as he puts his Kaenken Rekka in his driver.)

REKKA BATTOU! DONNA TOKI MO TAISETSU NA MONO O MAMORU TAME SEIGI GA TSUMUGU SHŌRI NO REKISHI! SUPER HERO SENKI! JIDAI GA NOZOMU KAGIRI HERO WA KANARAZU ARAWARERU!

(Then Saber and Zenkaizer merge into the Super Hero Senki Form.)

Saber: Let's go!

(Saber charges at Storious and strikes him, slashing him a lot of times before preparing to finish him.)

SUPER HERO HISSATSU DOKUHA!

(Emulating ZenkaiOh's combination sequence, Saber appears in a stadium with a giant projection of himself, controlled by Zenkaizer, in the background. Two giant drawings of Akarenger and Kamen Rider 1 appear, which Zenkaizer combines in a swirling mass of multicolored energy, creating a giant multicolored energy ball.)

REKKA BATTOU!

(Saber covers the Kaenken Rekka in multicolored energy and swings it, causing the projection controlled by Zenkaizer to do the same and launch a giant multicolored energy slash.)

SUPER HERO HISSATSU GIRI!

(The slash collides with the energy ball, launching it forward. The energy ball creates a giant multicolored energy shockwave upon striking Storious before resulting in an explosion, which reverts Storious to Lex Luthor.)

Luthor: (weakly) Is that... a new story?... Even so... the world... will... end...

(Superman approaches his defeated archenemy.)

Superman: The only thing will end here is your plan, Luthor!

(Hours later, Nathaniel and Owen are seen lookin at each other.)

Nathaniel: I guess this is it, huh?

Owen: Yeah, I'm going to continue my journey. I'll have to help someone named Jiro Serizawa and his new group of heroes. See ya.

(The other Riders return to their respective worlds while Zenkaiser goes to the Daikaiju-Verse.)

Saber: Riders and Sentai are immortal. We will continue to fight for this world and its people. (looks at the sky) We will be at everyone's side forever.

(The battle is finally over thanks to Kamen Rider Saber.)
