G&D Altman's steel combustion form, also known as solid combustion form, is the second combat form of G&D, which is formed by the fusion and sublimation of capsules of Severnissan and Leonnissan. The whole body is covered with hard armor and can exert rigidity. The ejector of the body can spray steam or flame to push it, and it is good at hand-to-hand combat, which means that the killing skill is the buster-increasing light (impact increase) emitted by the right hand.
