Bai Guiying

Corporal Bai Guiying (Chinese: 白桂英, tr. Bái Guìyīng) is a People's Liberation Army soldier who is responsible for making all grownup guests in the How I Can Help Make the World Great afterparty faint into temporary unconsciousness with sleeping agents when they make a toast, forcing the kid heroes who attend to fight against the Magna Men.

Once the Magna Men were defeated, he was arrested by the kid heroes for this crime, and in the Walkerville Trials, he was sentenced to death by firing squad.

On the day before his execution, he committed a seppuku with his family's dadao, hoping that his suicide is to forgive himself from his past war crimes (including putting all the grownups to sleep with the poisoned champagnes), thus escaping the awaiting execution.

Trivia

 * Cpl. Bai Guiying is reminiscent to the Spy Kids 2: The Island of Lost Dreams villains, such as Gary Giggles and Donnagon Giggles, and with a touch of Gerti Giggles and Romero (hence the poisoning plot during the banquet scene), yet he's also reminiscent to General Korechika Anami (for doing his own seppuku).
