A graduate of a Parisian École des Beaux-Arts,[3] Invader initially derived inspiration for his creations from the video games he played when he was growing up in the 1970s and 80s.

"[12] In 2012, Invader made a short film Art4Space documenting his attempt to launch one of his aliens into space on a modified weather balloon.

[19] He believes that museums and galleries are not accessible to everyone, and so installs his work at street level for ordinary people to enjoy on a daily basis.

Although many of his works feature his signature aliens,[5][7] Invader's repertoire of subjects also includes Star Wars characters, the Pink Panther, Mega Man,[21][22] Spider-Man,[23][24] Hong Kong Phooey, Thomas from Kung-Fu Master and Popeye.

Since 2004, Invader has also created a series of works, typically for indoor display, exclusively using Rubik's Cubes (a style the artist calls "Rubikcubism," a play on the Cubist art movement of the early 20th century).

[29] The works are organized into three series: "Bad Men," comprising portraits of famous villains such as Osama bin Laden, Jaws and Al Capone; "Masterpieces," which reproduces famous paintings by artists such as Delacroix, Warhol, Seurat, and Lichtenstein; and "Low Fidelity," based on iconic album art such as Country Life, The Velvet Underground & Nico, and Nevermind.

[12][29][31] Among the images Invader has created using this technique are those of the Mona Lisa and the Dalai Lama;[5] he received particular attention for a 2005 portrait of Florence Rey.

[3] Invader has had solo exhibitions at art galleries in Paris, Osaka, Melbourne, Los Angeles, New York City,[32] London, Rome [33] and Lyon at Galerie de Bellecour (now Michali Gallery, Palm Beach; exhibition for which he created the famous "Rubik Mona Lisa").

In 2010, he was included in the Banksy documentary Exit Through the Gift Shop, filmed by fellow urban artist Thierry Guetta (AKA Mr. Brainwash), whom Invader has claimed is his cousin.

Fellow street artist Shepard Fairey wrote in Swindle:Invader's pop art may seem shallow, but by taking the risk of illegally re-contextualizing video game characters in an urban environment that provides more chaotic social interaction than a gamer's bedroom, he makes a statement about the desensitizing nature of video games and consumer culture.

[41] In 2017, following an "invasion" in Ravenna, Italy (famed for its ancient mosaics), Invader installed a series of vegetarian-themed works in the "Veggietown" neighborhood of Paris (9th and 10th arr.)
