|“||It is a good thing you are here. Your owners were wise to give you permission to come.||”|
Sass is currently dormant in his Miraculous within the Miracle Box, being kept by Marinette Dupain-Cheng. When the situation requires it, he temporarily becomes active to help Luka Couffaine transform into Viperion.
Sass is 10 centimeters (or 4 inches) tall and is sea green, and has a broad, triangular head, resembling a cobra. His eyes are yellow with narrow black pupils, his mouth has two pointed fangs, and he has a sea green forked tongue. Additionally, he has a long tail, and from the top of his head and down his back to the tip of his tail, he has a black diamond line pattern.
Sass is the defacto leader of the kwamis in the Miracle Box, meaning he is mature, charming, calm and serious.
Like Longg, he has a bit of a formal side happily greeting his owners. Due to the unique ability of his powers, Sass has high expectations of those he is partnered with.
Sass can fly, levitate, and phase through solid objects. He can also carry objects that are larger and/or heavier than himself.
As a kwami, Sass is able to transform the holder of the Snake Miraculous into a snake-themed superhero, with the power to go back in time with Second Chance. It seems that Sass can fuse his powers with Plagg's to create the hybrid wielder Snake Noir.
Sass treats Tikki and Plagg as equals and considers them of being high virtue, given that he assumed they both got permission from their owners and from the Great Guardian of the Miraculous to participate in the ceremony inside the Miracle Box.
Sass appears to have a friendly relationship with Adrien, though he likely left a poor impression on Sass after failing to make good use of Second Chance over 25,900 times.
In "Miracle Queen", after Sass' Miraculous was taken from a mind controlled Luka, he was fed some cheese by Cat Noir before unifying his power with the Cat Miraculous' to become Snake Noir. It's likely that Sass' impression on Adrien started to change, as the boy was more focused on wanting to save his friends.
Sass appears to get along well with Luka. He likely thinks highly of Luka after comparing him to his recent temporary owner, Adrien, who proved to be a failure with the Snake Miraculous.
Even though his Miraculous wasn't activated, Sass helped Marinette as Multimouse enact her plan to rescue Tikki and Plagg by having her ride in his mouth. After Kwamibuster's defeat, he praised Marinette as her plan was a success.
Before Season 2
When the concept of Intuition came into existence, Sass came into existence. Before the Miraculous jewels were created, Sass and the other kwamis traveled all over the universe unable to interact with humans. Then, thousands of years ago, a mage created the Miraculouses. When its Miraculous was not being worn, Sass was dormant in the Snake Miraculous, which was stored inside Wang Fu's Miraculous jewelry box.
As of Season 2, Sass is dormant in the Snake Miraculous.
In "Sandboy", Sass was celebrating Nooroo's birthday in the Miraculous Box with the others kwamis and was excited when Tikki and Plagg arrived. As the other kwamis marveled at the gift Tikki brought, he expressed his thanks to Tikki's and Plagg's owners for letting them attend. He noticed Tikki trying to say her owner's name but understood what she meant and that they received the guardian's permission and played with the other kwamis. When the time came to find Nooroo, Sass commanded the kwamis into position but they realized they did not have enough kwamis singing to make the connection. He pointed out that they were missing Duusu and seeing this as their only opportunity to find Nooroo, he told Plagg to get Wayzz, who was standing guard in case Fu woke up. Wayzz's presence allowed them to make contact with Nooro, they contacted Hawk Moth instead. Upon hearing his voice, he shuddered at the thought of being his slave and prevented themselves from being discovered when they all cut off the connection. They realized if they contacted Hawk Moth, rather than Nooroo, then someone must have been akumatized, and Tikki and Plagg's wielders were in danger.
In "Desperada", Sass came out of the Snake Miraculous when it was temporarily given to Adrien by Ladybug. Sass then helped Adrien transform into Aspik, but his power were used in several failed attempts to save Ladybug and defeat Desperada. After numerous failures, Aspik immediately detransformed, with Sass landing in Adrien's hands exhausted, and returned to the Snake Miraculous to Ladybug, who then gave it to Luka instead. After Sass introduced himself and told Luka how to transform, they both transformed into Viperion and used Second Chance to devise a plan and help Ladybug and Cat Noir in defeating Desperada. After that, Sass was dormant in the Snake Miraculous again and returned to Ladybug, then to Master Fu.
In "Kwamibuster", he was activated along with his kwami brothers and sisters to help Multimouse enact her plan of rescuing Tikki and Plagg. During the confrontation, Sass was one of the few kwamis captured but was set free with the help of Multicat. After Kwamibuster's defeat Sass and others cheered for Marinette as their plan was a success and was returned to Miracle Box.
In "Miracle Queen ", he was activated by a mind controlled Luka, transforming for him into Viperion and his powers was used against the heroes until Dragon Bug and Cat Noir managed to retrieve his Miraculous. After eating a wedge of cheese to recharge, he fused his powers with Plagg's to transform Cat Noir into Snake Noir. With the power of Second Chance and Cataclysm, they were able to stop Miracle Queen and save their allies. Afterwards, he defused and after Ladybug retrieved the Miracle Box, he returned to his Miraculous.
