Kidpool is a variant of Deadpool appearing in Deadpool & Wolverine. He is a small, masked, childlike version of Wade Wilson from an alternate universe, retaining Deadpool’s chaotic humor, violent combat style, and constant pop-culture references. In the film, Kidpool serves as a comedic cameo and part of the multiversal lineup of Deadpool variants, helping emphasize the movie’s absurd, self-aware tone and the wider Marvel multiverse concept.
