Zero's plan was to gain Giratina powers and try to protect (or, in Ash's perspective, destroy) the Reverse World. He has long, silver hair. He was once Newton Graceland's student in studying the Reverse World, but he became obsessed with Giratina's power and decided to capture it. Using a machine designed by Newton himself, Zero was able to capture and unleash Giratina's power. He used the machine to cause destruction in the real world by damaging the Reverse World., However, his plans were thwarted by Ash and his team as well as Giratina. Zero was then stuck under an encasement of ice from many Ice attacks from native Pokémon as well as Dawn's Buneary and Swinub. Due to him being trapped like this, he lost all data on Giratina. Zero was then broken out from the ice and brought to jail. He made a brief cameo in Arceus and the Jewel of Life. During the end credits, he's visited by Newton who has recovered Infi.
Magnezone is Zero's main Pokémon and the only one he keeps close to him. Its job ranges from battling, like any usual trained Pokémon, to more advanced jobs, like leading Zero's Magnemite and Magneton army. Zero is also seen using it as a form of temporary transportation in that he will stand on Magnezone, and it will float him to locations he needs to reach. It was shown to be fast, powerful, durable, and as ruthless as Zero himself in pursuing Shaymin. After Zero was arrested, Magnezone and the Magnemite army took up residence on the Megarig's wreck in Gracidea.
