SCP 001

SCP-001, also known as the "Gate Guardian," is a powerful entity that actively guards a dimensional gateway, instantly obliterating any entity that comes within a kilometer radius of it, effectively acting as a barrier to prevent anything from entering or exiting the gateway, usually by utilizing a flaming sword-like weapon to vaporize threats on approach; it is considered one of the most dangerous SCPs due to its immense destructive capabilities and unwavering defense of the gate.
