It was the Lightning Gundam with the backpack being exchanged for a new one known as Lightning Back Weapon System Mk-III. It was built with a transformation function for Flight Mode, allowing high speed movement.

The LBWS Mk-III was built as the new backpack of the Lightning Gundam that Yuuma Kousaka used in the 14th Gunpla Championship. When equipped, the Lightning Gundam became the Lightning Gundam Strider and can transform into Flight Mode when combined with the Custom Rifle. The LBWS Mk-III is also capable of operating separately as a support machine.

Yuuma used the Lightning Gundam Strider during 14th Gunpla Championship and in the incident at the Nielsen Labs. In the latter, it easily destroyed Mocks and Hi-Mocks, but was powerless against the Scramble Gundam until Yuuma piloted the unit through the Plavsky Power Gate and combined with the Kamiki Burning Gundam.
