You can customize your PC screen by setting a desktop background with a popular manga character. I recommend you use Goku pictures as your desktop wallpaper. This is the wallpaper of Kamehameha of Son Goku. Son Goku, the main protagonist in Dragon Ball manga, has a special technique in fighting named Kamehameha, which is also usually named Kamehame. Kamehame is a special technique with the first energy attack shown in the Dragon Ball series. This technique is the most widely used for finishing an attack in a battle.
