The Hi-Zack was a sort of "new and improved" version of the Zaku II, making its first appearance in Z Gundam: 
 
 The lighter alloy used for its construction allowed for the installation of larger fuel tanks and more powerful thrusters, improving manoeuvrability in combat; this, plus easy maintenance, made the machine was popular among its pilots.
 Bandai has reproduced this fantastic machine (designed by Kunio Ohkawara) in a Master Grade kit with their usual attention to detail and stupendous quality!
 Dry-transfer decals and stickers are included for details.
