Killer Snail It chases you to kill you. It is the size of a normal snail. This snail can pull many things out of its shell, such as pistols and bazookas. It says "I KILL YOU" while chasing you. It can say other things, but it mostly says variations of "I KILL YOU." It will follow you anywhere—space, the ocean, or the sky. It feels pain from salt but does not die. Coffee is also a weakness, but it won't die from it; it only gets incapacitated for a while. This snail fears France (because they eat snails in France). This snail has hands and feet (...). If it takes off the shell on its back, it is faster than a car. It has a certain level of intelligence, and its only goal is to kill you. It uses a tycoon named Gu Cheon-jo as its mount; incidentally, it calls Gu Cheon-jo "Poppy." It also calls SCP-096, SCP-173, and SCP-682 "Poppy 2, 3, and 4." By the way, it has defeated all SCPs (including 682). In truth, this Killer Snail is trying to kill you to get the 13 billion won reward to pay for its grandmother's medical bills. It is possible to have a conversation with it. It is pink and carries a shell on its back. It speaks only in English (e.g., I KILL YOU, I hate you, I love you). If the snail fails to kill you within 5 years, it will die. The snail succeeds in its mission only if it touches you with its hand. Other weaknesses include copper, alcohol, and baking soda. It dies if it comes into contact with a component found in mud (Pseudomonas).

Three French Chefs Three chefs from a specialty snail restaurant in France. They believe the Killer Snail is the ultimate ingredient. You can meet them if you go to a French restaurant. They were once defeated by the Killer Snail, but they still haven't given up on cooking it.

Gu Cheon-jo Born with a vibranium spoon. He has a fortune of approximately 9 quadrillion won. He wears a white cloak and has black hair. He is used like a car by the Killer Snail. The Killer Snail calls him "Poppy." He calls the snail "Lord Snail." He was captured by the snail against his will, so he naturally hates this job.

Dr. Snail A doctor who researches snails. He is well-versed in the structure and weaknesses of the Killer Snail. He has messy white hair and wears glasses. He is currently planning to eliminate the Killer Snail along with Gu Cheon-jo. He is very intelligent.
