The GAT-X105B/EG Build Strike Exceed Galaxy (aka Exceed Galaxy) is a Gunpla introduced in the Gundam Build Metaverse. It is built and piloted by Sei Iori.

A new Build Strike based on the Entry Grade 1/144 GAT-X105 Strike Gundam. By taking another look at the Entry Grade Gunpla, one made for builders regardless of stripes, Sei tried to discover what kind of novel potential the Build Strike housed. The completed Build Strike Exceed Galaxy adopted a new energy super-light circulation mechanism called the "EG (Energy Glitter-circulation) System" based on the RG System, which is capable of multidimensional boost-ups to suit the battle situation. Sei also added hardpoints to various parts of the Build Strike Exceed Galaxy and its equipment, allowing for a wide variety of weapon loadouts so that it would fulfill his dream of a Gunpla that had no final form, but rather unlimited potential. The Gunpla's name, "Exceed Galaxy", also symbolizes this desire.
