Marvel: Spider-Man? I am Uncle K of the Vampire Clan!

Ye Yu traveled to the world of Marvel and obtained the Knight Assistance System.

"The system opens a gift package for newbies."

"Congratulations to the host for obtaining the complete power of the vampire Killbus in Kamen Rider Build."

"Oh, the complete power of Uncle K, that's enough for the time being."

"In that case, then! Here I come to the wonderful world of Marvel."

...........

Peter Parker: "Ye Yu, why are you so much stronger than me as a spider?"

Tony Stark: "Oh, Mr. Ye, please sell me your armor technology for any amount of money."

Nick Fury: "Mr. Ye, please join S.H.I.E.L.D."

Gwen: "Ye Yu!"

Wanda: "Ye Yu, give me a new magic!"

During the final battle, Thanos looked at the powerful King of Demons and said, "I shouldn't have come to Earth."
