Section 4 Gravity Block is the room in which MB's original body was stored, in Sector Zero, in Metroid: Other M. Named on a hologram in the Bioweapon Research Center's main room, MB's android body informs Samus Aran of Project Metroid Warriors when they reunite in the center. A hologram is projected from the room's main computer displaying information about the room, including multiple issue reports, but a message repeatedly states no issues have been detected. Samus never got to explore this room, as Adam detached the sector rather than her.
