Viewtiful Joe (ビューティフル ジョー, Byūtifuru Jō) is a video game developed by Capcom's Production Studio 4 for the Nintendo GameCube. It was originally released in 2003 as a part of the Capcom Five under director Hideki Kamiya and producer Atsushi Inaba. Viewtiful Joe was later ported to the Sony PlayStation 2 (PS2) by the same design team under the name Clover Studio. The Japanese version of the PS2 release is titled Viewtiful Joe: A New Hope (ビューティフル ジョー 新たなる希望, Byūtifuru Jō: Aratanaru Kibō). The game's story concerns Joe, an avid movie-goer whose girlfriend Silvia is kidnapped during a film starring Joe's favorite superhero, Captain Blue. Joe is shortly thereafter thrust into Movieland, where Silvia is taken by the villainous group known as Jadow. After accepting a special V-Watch from Captain Blue, Joe transforms into the tokusatsu-style persona "Viewtiful Joe" and sets out to rescue her.

The gameplay of Viewtiful Joe features traditional 2D platform side-scrolling intermixed with 3D cel-shaded graphics. Abilities known as "VFX Powers" grant the player special actions for combat and puzzle-solving, such as slowing down or speeding up time. Viewtiful Joe was critically acclaimed for its unique visual style and gameplay, earning itself a number of awards from various media publications. A minor commercial success, the game spawned a few sequels with releases seen on other consoles such as the PlayStation Portable (PSP) and Nintendo DS. An anime adaption of the game was also produced.
