General Tyben was a highly regarded officer within the New Republic, recognized as one of their most skilled human military minds. While positioned on Chandrila, he oversaw the Battle of Jakku by directing the movements of soldiers on the ground.
As a male member of the New Republic, General Tyben was known as a top-tier military strategist. He also supervised the New Republic Special Forces, possessing the authority to authorize commandos to return to active duty.
Although he was not physically present, he played a crucial role in the Battle of Jakku by remotely guiding the ground forces under the command of Lieutenant General Brockway from the relative safety of Chandrila, a situation that frustrated him. Regardless, his troops steadily drove back the enemy, intending to attack their base before nightfall. Throughout the battle, Tyben communicated with Fleet Admiral Gial Ackbar via hologram, reporting on the numerous Republic casualties and the brutal, disorganized methods used by the Galactic Empire. He also expressed his regret at not being on Jakku in person, but Ackbar abruptly ended the transmission.
Tyben, a fair-skinned man with a shaved head, was described as having a head shaped like a square ice cube. His shoulders were noticeably narrow. Renowned as one of the New Republic's finest military strategists, Tyben desired to be actively involved in combat, as opposed to directing operations from afar.
