Battle of Algolis

Main article: Battle of Algolis

She was heavily damaged when a Covenant boarding party attacked the Heart of Midlothian. Huragok brought onboard separated Mo Ye from her core, leaving just a chunk of her connected, which was watching over a surgery. Unable to self-destruct, the AI told the only survivor on the ship, an ODST Sergeant named Michael Baird, to make his way to the control room and instigate an attraction coordinate. After Baird was severely hurt by a Sangheili wielding an Energy Sword, Mo Ye gave Baird a Waverly augmenter, used by the Insurrectionists to fight Spartans-IIs, which would keep him alive for one or two hours. Mo Ye couldn't help Baird to go on without being connected. Mo Ye was then reconnected by Baird, who was surrounded by Covenant, with the intention of "giving the Covenant the coordinates of Earth". Baird, aware that she couldn't destroy the ship with any human alive, punched the Elite besides him as hard as he could, breaking his hand. Baird began to taunt the Elite until it recovered from the impact and beheaded Baird. Mo Ye started the countdown. While the boarding party left, Mo Ye and the Elite glanced at each other until she said "Just kidding. There's no need for countdown whatsoever." Mo Ye was destroyed when she put the ship into self-destruct, leaving nothing but the midnight of space.[1]


  • Her name appears to be a reference to Mo Ye, a swordsmith from a Chinese folk tale who sacrificed herself in order to successfully forge a sword that was also named after her. This may be a nod to the naming of two of Bungie's previous AI constructs; Durandal from Marathon and Cortana from Halo. Both of their names are linked to mythological swords.
