Technology & Combat Characteristics
The Gundam Astray No-Name is specialized for the GP Duel (aka GPD, Gunpla Duel), an older system for Gunpla Battle in which Gunplas fight each other in the real world, and Tsukasa had used it in over 500 battles. Each time Tsukasa lost, he repaired, customized and improved it into its current form. The No-Name Unit not only has advanced offense and defense capabilities, but also has the "n_i_t_r_o System" from the MSN-001X Gundam Delta Kai featured in UC-MSV, which increases the fighter's ability.
