Bragza (ブラガ) is the indestructible core of Andor Genesis, and is also a mirror of GAMP. The core appears in every Xevious game to date, while it is the final boss in Xevious Resurrection. Bragza is shown to be the core of GAMP, and is implied that the core is sentient in itself. Bragza is also the core of every Andor Genesis mothership, and will flee when the Solvalou destroys the ship, and is completely indestructible much like the Bacura.
In Xevious Resurrection, the Bragza appears as the final boss of the game, encased in a gelatinous-like substance. and is the only instance in the series where the core can be destroyed. Bragza attacks using circular lasers and homing in on the Solvalou. The core protrudes from GAMP instead of an Andor Genesis mothership, indicating that the Bragza shown in this game is in fact the core of GAMP itself.
