The Snake Miraculous is a sea green bracelet. In its charged mode, the bracelet features a snake which can be slid back to reveal a yellow forked tongue, divided into five parts. In its camouflage mode, it's silver for both Luka and Adrien.
The Snake Miraculous provides its wielder superhuman characteristics of strength, speed, durability, and agility. Its special weapon is a green Lyre.
Its special superpower is called Second Chance, allowing the user to mark a point in time by sliding the snake on the Miraculous and return to it. The user's memory remains untouched, allowing them to correct anything that may have happened before going back in time. The user can use this power for how much times they want as long they do it within the five minutes limit once the power is activated.
The snake is modeled after an Ouroboros, a symbol of a snake biting or eating its own tail. It is a symbol of self-reflexivity, cyclical, and eternal return.
The Snake Miraculous is stored in a drawer in the Miracle Box.
It is the second Miraculous shown to be able to manipulate time, following the Rabbit Miraculous.
Unlike the Rabbit Miraculous, the Snake Miraculous is only capable of going backwards in time for a few seconds or minutes. The Rabbit Miraculous is capable of manipulate time both backwards or forward.
While the Snake Miraculous allows to go back to change events, the Rabbit allows to go back to participate in them, while not changing the future the user came from.
According to Dragon Bug, the Snake Miraculous is one of the most dangerous Miraculouses if it used for evil.
