Also, I recall Doraemon to not be a weapon, but just a helpful servant. Yes the gadgets have lethal capabilities but they are never made for harming purposes.
You might think Doraemon is all fun and wholesome, but trust me, it has its dark side. There are movies and episodes that were so disturbing they ended up being banned because kids couldn’t handle them. About four years ago, I saw a reel that gave me chills, showcasing a Doraemon episode like nothing I’d ever seen before.
Doraemon looked terrifying. His usually cheerful expression was replaced by something sinister—a wide, unnatural grin stretched across his face, and his eyes glowed a menacing blood-red. His movements were jerky, almost robotic, as though something inside him had gone horribly wrong. He arrived at Nobita's house, scanning the room like a predator searching for prey. When he found Nobita diligently doing his homework at the desk, the scene turned even darker. Without a word, Doraemon pulled out his air cannon and began firing. The shots echoed through the room as Nobita sat completely still, unmoving, taking blast after blast. It was horrifying—Nobita didn’t even flinch, like he was already… gone.
But then, the door creaked open. A shadow fell across the room, and there stood another Nobita. Yes, another Nobita. He looked confused, seeing his robotic companion holding a smoking air cannon. “What’s going on?” he asked nervously. Doraemon, his sinister grin still plastered on his face, turned to him. The red glow in his eyes seemed to intensify as he answered, “I… don’t know…” and started walking toward Nobita.
The real Nobita quickly pieced it together—the “Nobita” at the desk had been a decoy, created using Doraemon's cloning gadget. He had set it up to trick his mom into thinking he was studying while he sneaked off to meet Shizuka. But something had gone horribly wrong. As Doraemon advanced, air cannon in hand, Nobita could feel the oppressive weight of fear building. “Stay back!” he yelled, but his voice wavered. Doraemon ignored him, his grin widening unnaturally as if he was feeding off Nobita's terror.
Realizing the danger, Nobita tried to back away, but Doraemon’s speed was unnerving. Without warning, he raised the cannon and fired. The blasts were relentless, tearing through furniture as Nobita dodged with desperate, clumsy movements. It was pure chaos—Doraemon's usual calm demeanor replaced with a relentless bloodlust. The house became a warzone, Nobita narrowly evading shot after shot, his heart racing as the usually familiar and safe Doraemon transformed into his worst nightmare.
Eventually, they discovered the horrifying truth: Doraemon’s rule and obedience chip—the component that made him friendly and loyal—had been damaged. Without it, the robot that was supposed to be Nobita’s best friend had turned into a dangerous, unpredictable killer. The revelation was chilling. One tiny malfunction, and Doraemon had become a threat capable of ending his best friend Nobita’s life in an instant.
Btw, those robots and doraemon were made to become friends with humans, not some slave. Also the reply might sound a bit dramatic and novelish but I was just trying to get u the feel of the scene but I might have failed but anyways, all I wanna say is, Doraemon is not a friend, nor slave. He is ticking time bomb, one internal malfunction = horrific outside destruction
