Bandai 1/100 MG GX-9901-DX Gundam Double X

The GX-9901-DX Gundam DX was created by mobile suit engineers of the newly formed New United Nations Earth (NUNE). NUNE engineers reversed engineered the MS technology of GX-9900 Gundam X and created a more powerful version from the original. Doubling (if not tripling) the capabilities Gundam X had, they dubbed the unit as Double X.
