he Dreadnought Gundam rolled out in February, C.E. 71. It was test piloted by Courtney Heironimus and was dismantled after testing was completed. Siegel Clyne secretly arranged for the disassembled parts to be handed over to Prayer Reverie so that he could bring it to Reverend Malchio on Earth, who wanted to use its N-Jammer Canceller technology to end the planet's energy crisis. However, Prayer's ship was attacked by Serpent Tail during the journey and the Dreadnought's head, which contained the N-Jammer Canceller, was stolen. After a series of events, the Dreadnought's parts were acquired and assembled by Lowe Guele and his companions, with the missing head replaced by a GuAIZ's head. Due to this change, the suit could not use its Phase Shift armor and was instead battery powered. It was then piloted by Prayer in a failed attempt to stop an attack by ZAFT forces.
