After the destruction of Dolza's fleet at the end of the First Robotech War the majority of the remaining Zentraedi on Earth were integrated into human society. Some Zentraedi, however, could not acclimate and joined with renegade Zentraedi elements scattered around the globe. These groups of Zentraedi were collectively known as Malcontents. In 2018 a new leader emerged who unified the various Malcontent groups into a new Zentraedi army and led them in one last violent struggle against humanity. This struggle came to be called the Malcontent Uprisings, and the war's consequences would alter the balance of power on Earth for decades to come.
