Disney's PK: Out of the Shadows
The PK character may be unfamiliar to American audiences, but in Italy (and some other parts of Europe) he is popular through a series of comics. This game is a simple 3rd-person action shooter game. You control PK as he aims his blasters at Evronian soldiers, jumps through colorful environments and rescues captured scientists.
Story
Donald Duck was going about his boring job as a security guard one day when the evil Evronian Empire decided to attack Earth. A computer being named One discovered the invasion early and teamed up with Donald to transform him into the superhero PK. Now it's PK's job to repel the alien invasion.
