Plagg is the kwami connected to the Cat Miraculous, which is what he stays in when inactive while being protected by Master Wang Fu. Currently, he lets Adrien Agreste transform into Cat Noir.
Before Season 1
When the idea of destruction came into existence, Plagg came into existence. He traveled along with the other kwamis through the universe until a mage created his Miraculous.
However, Plagg was responsible for multiple disastrous events in the past when he used his powers without his owners, such as making the dinosaurs disappear, sunk Atlantis, and (in a more modern event) toppled the tower of Pisa. He said that he simply didn't see the tower of Pisa when he flew into it and had too much cheese in Atlantis, but did admit he went a bit overboard with the dinosaurs.
For over 5,000 years, Plagg has helped people transform into cat-themed superheroes in order to save the world. He started out in China, next went to Mexico, then Italy and Europe.
At one point, Plagg met the genie of the lamp and learned how to play the piano, he currently resides with Adrien in his mansion in Paris, France.

He emphasized that Adrien could not tell anyone about his existence. Before he could finish telling Adrien about his powers, they transformed into Cat Noir. Together, with the help of Ladybug, they took down Stoneheart. However, because Ladybug did not capture the akuma, it multiplied and spread, creating more Stonehearts.
