CEK-077 Beguir-Pente (ベギルペンデ Begirupende?) is a mobile suit introduced in Mobile Suit Gundam the Witch from Mercury. It is piloted by the members of Grassley House.

A successor to the CEK-040 Beguir-Beu developed by Grassley Defense Systems. A high-performance mobile suit that incorporates Non-Kinetic Effectors, the core elements of the Anti-GUND Format equipment. Like its predecessor, the Beguir-Pente can release "Antidote" attacks that interfere with GUND FORMAT links. However, these "Antidote" attacks only affect GUND FORMAT links with Permet scores of 3 or lower.
