History:
Maseo Yamashiro (died May 2015) was one of the former mentors, former handlers, and an old friend of Oliver Queen. Maseo was also the estranged husband of Tatsu Yamashiro and the father of the late Akio Yamashiro. Sometime after Hong Kong, Maseo joined the League of Assassins, around the same time Sara Lance did. From then on, he came to be known as merely Sarab (Arabic: سراب; for Mirage), refusing to use his former name entirely.

Powers:
 As a former A.R.G.U.S. operative and a member of the League of Assassins, Maseo was shown to be in top physical condition. His reflexes allowed him to catch an arrow shot at him by Oliver Queen, and his strength was such that Oliver needed to put in considerable effort to overwhelm him in one-on-one combat despite the latter's strength.  Even before joining the League of Assassins, Maseo was shown to be highly skilled in close combat and martial arts, enough to beat Oliver. Maseo had also gone through the training all League members do. His training from the League appears to have improved his abilities, able to swiftly defeat Quentin Lance and managed to pressure and contend with Oliver now as the Arrow, with Oliver defeating Maseo with considerable difficulty. Maseo also fought almost on par with Nyssa al Ghul but only defeated her when she was distracted.  Maseo was shown to be highly skilled with firearms, being able to shoot a cell phone out of Oliver's hand.  Due to his training with the League of Assassins and the fact that he carried arrows in a quiver, Maseo was an expert archer. He shot an arrow with great accuracy through a window to assassinate mayor Celia Castle.  Due to his training with the League of Assassins, and the fact that he wielded a katana, Maseo was an exceptional swordsman. He was able to kill three of his fellow assassins with his sword with ease and was able to go up against Nyssa in a swordfight. In his confrontation with Tatsu, Maseo was proven to be the superior swordsman.  Maseo was highly skilled at designing plans to break into secured buildings and abduct people from public spaces in broad daylight. He had a leading role in the League, as Nyssa mentioned he would lead the executions in Starling City if the deadline had passed and Chase reported to him while on the hunt for Malcolm Merlyn.  As a native Japanese, Maseo spoke that language fluently, in addition to Mandarin, English and Arabic.  Due to his League of Assassins' training, Maseo had a high tolerance for pain as seen he was able to cut his own neck in order to provide an alibi for Oliver without flinching.
