A scientific genius with a troubled mind, Captain Ackbar spent much of his life roaming the stars in a ship of his own design. After witnessing his homeworld captured and his people enslaved by the Empire, he gathered a loyal crew and fled into deep space, planning to escape civilization entirely.
For the next sixteen years, not a trace of Ackbar or his crew was seen. Meanwhile, the Empire continued to spread, and soon even the darkest corners of the galaxy would hold no sanctuary for Ackbar. As suddenly as he disappeared, a surprise attack on a vital Imperial supply ship signaled Ackbar's return, and the beginning of a long and impressive guerrilla campaign against the Empire. Like a phantom, Ackbar and his ship haunted the Empire, swooping in and hitting them whenever and wherever they were most vulnerable before disappearing into the void without a trace. The stories of his deeds made him a folk hero among resistance supporters and a fearsome figure to Imperial Stormtroops.
After the annihilation of Alderaan, Ackbar ended his lone campaign and officially joined forces with the Resistance.
