Who is Wreck-It Ralph's enemy in "Wreck-It Ralph"?

Wreck-It Ralph’s enemy in “Wreck-It Ralph” is Fix-It Felix, Jr., the heroic character in Ralph’s arcade game. Ralph plays the game’s villain, destroying an apartment building, while Felix repairs the damage with his magical golden hammer and receives praise from the building’s residents.

Their conflict begins with Ralph’s frustration at being excluded from the game’s celebrations. Although Ralph is essential to the game, he is treated as a villain because wrecking the building is his assigned role. Felix, by contrast, is celebrated as the “Good Guy,” creating the central rivalry between them.

Ralph eventually leaves the game to win a medal and prove that he can be a hero. His journey takes him through other arcade worlds, including the first-person shooter “Hero’s Duty” and the candy-racing game “Sugar Rush.” The story complicates the apparent good-versus-evil setup: Felix is Ralph’s rival, but the film ultimately shows that Ralph and Felix are friends and complementary parts of the same game.
