Doraemon's most terrifying gadgets teach lessons on negative emotions

The beloved Doraemon manga, created by Fujiko F. Fujio, is known for its magical gadgets like the Anywhere Door and Time Machine. However, the series also introduced some terrifying inventions that could be misused for revenge and hatred.

These stories convey a message that hatred rarely yields good results and warn of the unpredictable consequences of letting negative emotions dictate actions. One of the most frightening gadgets is the "Cursed Camera." After being mocked by Suneo, Nobita, in tears, receives this camera from Doraemon. It creates a voodoo doll identical to the person photographed, and any harm inflicted on the doll transfers directly to the real person.

Even Doraemon hesitates to use this dangerous item. The situation escalates when Nobita accidentally photographs Doraemon and his parents, creating dolls that fall into the hands of Jaiko and Ganko. Unaware of the camera's true nature, the girls play doctor with the dolls, put them in the refrigerator, and even consider breaking their necks.

Another notable gadget is the "Revenge Bill." This item, mistakenly sent from a 22nd-century department store, allows the user to write down damages they've suffered and discard the bill. Whoever finds it then carries out the revenge on their behalf. Nobita immediately plans to use it against Gian, despite Doraemon's warnings about its cowardly nature and negative outcomes. However, the bill is found by Nobita's teacher, forcing Nobita to enact revenge on Gian himself, resulting in a beating. In a second attempt, Shizuka finds the bill, and Nobita, wanting to protect her, takes it back, only to face the consequences himself again. The "Position Swap Gun" is also presented as a mentally terrifying gadget, allowing users to transfer a portion of their soul into another's body when witnessing bullying.
