404

Robert Louis Stevenson, the famous author, had displayed the feeling of seeing 404 in his book 'Treasure Island' in the chapter 'The Black Spot'. If you encounter the vicious 404, you will die of shock or worse, you will die of force when you smash the computer on your forehead. No one has come back from a scouting mission with 404, but it is said that a hero called Elon would save the day and slay 404. But that time hasn't come yet, and 404 is still criminally active. Hopefully, he will die from the new disease, Ligma. (you thought I wouldn't put a Ligma joke in this definition, didn't you?)

You: "He is a big supporter you You-Know-Who!"
Harry Potter: "What? 404?"
You: "Don't speak his name!"

Tiger 404

An elite internet operator who prowls the web with deadly precision but leaves no tracks. Like a tiger stalking through digital jungle undergrowth, they're silent, patient, and utterly untraceable. “404” means you’ll never find them.

They find you.

Think we’re being tracked? Maybe. If it’s a Tiger 404, you won’t know until it’s too late. If ever.
