A mecha from the Macross series. The VF-3000 Crusader is a heavy variable fighter mecha featured in the Macross M3 Sega Dreamcast videogame.
It is basically a bigger/heavy fighter version of the original VF-1 Valkyrie.
It was originally designed by Kawamori Shouji in the late 80s for a variable fighter toy line from Bandai. When the line wasn't produced he kept the design and used it years later in the console video game.
