Invader is an anonymous French street artist. He is known for his ceramic tile mosaics modeled on the pixelated art of 1970s–1980s 8-bit video games, many of which depict the titular aliens from the arcade games Space Invaders, Pac-Man and Super Mario Bros. (the inspirations for his pseudonym). As of December 2020, his creations can be seen in highly-visible locations in 79 cities in 20 countries. To accompany his citywide installations, or "Invasions", Invader publishes books and maps as guides to the locations of his mosaics.
