The GAT-X105 Strike Gundam is initially designed by Junichi Akutsu and cleaned up by Kunio Okawara for the series Mobile Suit Gundam SEED as one of the five mobile suits developed under the Earth Alliance's G Project. In the real world, the GAT-X105's base design is closely (though not entirely) based on the original RX-78-2 Gundam and also shows strong design influences from the MSZ-006 Zeta Gundam.
