GBA- Astro Boy: Omega Factor

Omega Factor features elements from Astro Boy's different incarnations. The concept of robot rights, Dr. Tenma's ultimate plan for Astro and the robot city of Robotonia in Antarctica are lifted from the Astro Boy 2003 TV series. Plotlines from other Tezuka series include a time travel plot lifted from Marine Express, a journey to the lost continent of Mu, and a subplot involving Duke Red's daughter and her role in the "Death Mask" orbital platform. The game is divided into two episodes: Birth and Rebirth. The Birth episode follows Astro's adventures and other characters he interacts with, and ends with robots being destroyed by a device called Death Mask, after it determines that the robots are too dangerous to be left alive, leaving Sharaku able to conquer the Earth. In Rebirth, Astro is revived by a being called Phoenix, and has Astro go back to the beginning of the story and try to stop the Death Mask, giving him the ability to go back and forward in time to do so.
