XXXG-01S2 Altron Gundam The upgraded version of the Shenlong Gundam, now equipped with two Dragon Fang gauntlets (one in each forearm) and a beam trident replacing its predecessor's glaive. The Endless Waltz redesign gives the unit a sleeker look and a green finish, but does not alter its pilot - the ever tumultuous and problematic Chang Wufei.
