(Percy is seen with the lower part of his face covered in a mask as he overlooks the city.)

Percy: I swear I'll make you pay for murdering my brother, mom...

(Suddenly Giff comes in.)

Giff: Human... you must die...

(Suddenly a portal opens up, and Okuyasu Senki comes in.)

Okuyasu: Giff, the main antagonist of Kamen Rider Revice. It's you who will die. (prepares to transform) It's Morphin' Time!

(Percy pulls out the Eagle Trinket and the MiraiDriver is summoned as he prepares to transform.)

Percy: Henshin!

TRUTH! JUSTICE! AMERICAN WAY! KAMEN RIDER BIRTHRIGHT!

(Percy becomes Kamen Rider Birthright.)

Birthright: For truth, justice and the American Way! Kamen Rider Birthright!

Rainbow Ranger: Made of Pure Morphin' Grid Energy! Rainbow Ranger!

(They charge at Giff who fires energy beams from his hands, but they dodge them all while Rainbow Ranger blasts and slashes him, and Birthright punches him.)

Rainbow Ranger: (pulls out a key) Senki Change!

KAMEN RIDER HELLSING!

(Rainbow Ranger becomes Kamen Rider Hellsing and jumps at Giff as he punches him.)

Hellsing: Is that your best?

(Giff then launches an energy burst which pushes both Rainbow Ranger (Hellsing) and Birthright away.)

Hellsing: Thought so... (pulls out another key) Senki Change!

ULTRAMAN PATRIOT!

(Rainbow Ranger changes to Ultraman Patriot and creates a barrier with a shape similar to Captain America's shield as it protects him from Giff's laser.)

U. Patriot: Take this! Charging Star!

(Ultraman Patriot tackles Giff, and pushes him away while Birthright flies and prepares to execute his attack.)

EAGLE PUNCH!

(Birthright punches Giff, giving time for Ultraman Patriot to charge up his finisher.)

U. Patriot: STARS AND STRIPES CROSS SHOOT!

(Ultraman Patriot shoots a star-shaped beam at Giff, who screams in agony.)

Giff: CURSE YOU BIRTHRIGHT AND RAINBOW RANGER!

(Giff finally explodes as both Birthright and Rainbow Ranger leave the scene, unaware that a Neo H.Y.D.R.A. drone was watching the fight.)

(Cut to Neo H.Y.D.R.A. Base, Nancy slams her fist in the desk as she knows it's her other former crush.)

Nancy: (hatred overpower) OKUYASU SENKI! YOU ALSO REJECTED MY FEELINGS AS WELL!

(Suddenly Azu comes in with a driver similar to Ark Driver.)

Azu: It's time to become the next vessel of Ark-sama, Nancy.

(Nancy sees the driver and the Zetsumerisekey as she smirks deviously and picks them up before placing the driver in her waist.)

CORONA DRIVER!

CORONA!

(She scans the Zetsumerisekey.)

AUTHORISE!

Nancy: (smirks) Henshin!

PROGRISE! ARK! INFECTION! ISOLATION! QUARANTINE! CORONA THE KAMEN RIDER! SACRIFICING FREEDOM FOR A SAFE WORLD.

(Nancy becomes Kamen Rider Corona.)

Corona: Feel my sickness, because I will give them a pain, Kamen Rider Corona.

(Corona and Azu giggle evilly as they prepare for their next plan for world domination and laugh maniacally.)

(As the screen fades out, Kamen Rider Corona throws a symbiote at the screen and it says "To be continued" as she laughs maniacally and walks away.)
