(Kamen Rider OC X Small Crossover)
Percy Howard had a hard life. He lost his older brother Michael, his mother was the mastermind behind his death, and a new Coronavirus was unleashed. When hope seemed to be lost, Percy met Aruto Hiden, Touma Kamiya...
(At Hiden Intelligence, The heroes are shocked to see Osaka being conquered by Kamen Rider Corona, and Percy gets angry about it.)
Percy: That damn bitch... I'll make her pay for this!
(Percy then rushes as he transforms into Kamen Rider Birthright and flies towards Osaka.)
(Cut to Osaka, Azu is seen approaching Corona.)
Azu: Your stepson is approaching here.
(Corona turns to see the Black Dragon Ranger walking away.)
Black Dragon Ranger: I'll stop him!
(Then Black Dragon Ranger summons his Mega Black Dragonzord and jumps inside of it.)
(Back to Birthright, he is seen flying towards Osaka.)
Birthright: I must hurry!
(Out of a sudden, a hand catches him as he sees the Mega Black Dragonzord.)

Black Dragon Ranger: It can't be... (sees Birthright descending) Curse you!
(He suddenly sees electricity in his body.)
Black Dragon Ranger: No! It can't be!
