The Gundam AGE anime is not yet that old but here we already have the AGE-2 Normal. The AGE-2 takes over for the AGE-1 (linked below) and brings quite a lot of changes to the table. The biggest one - AGE-2 Normal can transform with only miminal parts swapping. In its regular form the AGE-2 Normal carries its weapon in its hand but in Strider form the weapon becomes the becomes part of the form itself. Included in this great HG kit are two beam sabers, extra hands, and even a display stand!
