Before Season 1
When the concept of protection came into existence, Wayzz came into existence. Wayzz and the other kwamis used to travel all over the universe unable to communicate with humans. Until thousands of years later when a mage created the Miraculouses. He stays with Master Wang Fu so the guardian can benefit from his advice.
In "Ladybug & Cat Noir", Wayzz is seen sleeping in a matchbox until he senses Nooroo's power being used for evil. He alerts Wang Fu of the disturbance and agrees that they must find Nooroo as soon as possible but disagrees that Wang is up to the task anymore. After Wang delivers the Cat and Ladybug Miraculouses, Wayzz asks his master if the new heroes will be up to the task.
Later, after Stoneheart has been defeated in "Stoneheart", Wayzz watched Marinette and Adrien with Wang nearby, complimenting on his choice of the new heroes.
In "The Collector", Wayzz watched Wang Fu mediating until Marinette arrived with the Miraculous spellbook. The kwami made himself known to her introducing himself and happily played with Tikki as their Miraculous holders talk.
Wayzz shared tea with Tikki on the phonograph in "Robostus" as Marinette and Wang talk about the combined power of the Ladybug Miraculous and Cat Miraculous.
When Wayzz saw Marinette come into Wang 's shop in "Sapotis", he told her it's too dangerous for her to come here but Wang calmed him down. After Marinette explained everything he watched with Wang as she takes the Fox Miraculous.
After Marinette returned the Fox Miraculous in "Syren", Master Wang spoke of modifying the kwamis powers. Wayzz along with Tikki begged him to tell them but the guardian warned the kwamis of what could happened if they were captured with that knowledge. Understanding the two went into hiding after the potion was complete Wayzz tested it and yet it didn't work as he said it needed more salt. After Syren caused the streets of Paris to flood he and Wang retreated to higher ground. When Marinette assured his master that they would find that last ingredient he and Tikki covered their ears. Upon finding it, Wayzz witnessed that the potion was a success. With Paris no longer under attack by an akumatized villain, Wayzz came to the Agreste Mansion with Master Wang Fu where they both officially met Adrien.
During "Anansi", Wayzz saw Marinette come into Master Fu's shop explaining that Nino couldn't hold off the villain for long and Cat Noir was about to lose his ring. As Wang offered Marinette to pick a temporary miraculous along with an ally he and Master Wang were surprised that she picked his and they agreed. Afterwards, Wayzz was introduced to Nino who thought he was a genie and yet clarified his was a kwami and transformed Nino into Carapace. With Ladybug, Cat Noir and Carapace's powers of shellter the trio were able to stop Anansi and save Alya.
Then, after the miraculous was returned to Ladybug, Wayzz was returned to Master Wang.
In "Sandboy", he saw Tikki and Plagg come in and told them not to wake Master Fu and before they left Wayzz told them to wish Nooroo a happy birthday from him while he stood guard. In the kwamis' attempt to contact Nooroo they realized they didn't have enough power, Wayzz was sought out by Plagg at first he refused to go but was convinced this was their only chance and went into the kwami's world. During their attempt to contact Nooroo they contacted his wielder instead and shuttered at the though of being Hawk Moth's slave.
To prevent being discovered they cut off the connected but realized that Hawk Moth akumatized someone and left with Tikki and Plagg to find their owners. He then saw Wang Fu being attacked by his greatest fear and apologized to him when he didn't tell him the whole truth but was told they'd talk about it later.

But was forgiven and informed to talk to him if he needs to asks something.

But when he saw the creature chase after them instead of Marinette; Wang tried to point out that he made the right choice and yet Wayzz retorted that she would've transformed and fought. He was informed by his master that fighting isn't always the answer however, Wayzz saw that running was pointless and that his disciples were fighting back despite being powerless and encouraged his master to follow their example and pushed him to do the right thing.
But with Wang, still remorseful, Wayzz put in his Miraculous and after Wang returned the jewels to his disciples he was released again happy that he made the right choice.
