Bandai has announced the release of two new heavy armament expansion sets for the popular “METAL BUILD EXPO Hi-ν Gundam”.
The “Hyper Mega Bazooka Launcher [METAL BUILD EXPO]“, which incorporates detailed new heavy arms that are created to match the exclusive color scheme of the “METAL BUILD EXPO Hi-v Gundam”, and its accompanying “METAL BUILD Hi-ν Gundam Dedicated HWS Option Set”, are set to allow fans to upgrade their existing setups.

The Hi-ν Gundam design famously originates from Mobile Suit Gundam: Beltorchika’s Children, a 1988 novel penned by series creator Yoshiyuki Tomino.

This alternate retelling of the Char’s Counterattack storyline introduced readers to uniquely bulked-up mobile suit designs that have since become incredibly sought after by mecha enthusiasts.

Bandai’s high-end METAL BUILD line is renowned for re-creating these legendary machines with striking internal metal frames and sharp aesthetics.

The “METAL BUILD Hyper Mega Bazooka Launcher [METAL BUILD EXPO]” brings back a highly praised super large weapon with refined coloring to perfectly match the recent METAL BUILD EXPO exclusive Hi-ν Gundam.

The energy cable, which is described as a tube in the original novel, has also been appropriately thickened to give it a much stronger visual presence when connected to the mobile suit.
