- Ultros (オルトロス,Orutorosu?), also known as Orthros, is a recurring enemy in the Final Fantasy series. Ultros is a carnivorous purple octopus with a writhing mass of tentacles who has a mouth full of fangs. He frequently cracks corny jokes and makes lecherous comments towards female party members. Ultros works with his partner Typhon, who provides the muscle Ultros lacks. Ultros first appeared in Final Fantasy VI as an incompetent but recurring boss, and has since been featured in several other games as an optional encounter.
- Ultros, using a modified version of his Final Fantasy XIII-2 model, appears in the Hildibrand Manderville sidequests for patch 2.4 as an receptionist for Dour Meadow at Master Fygreis's Coliseum. He attempts to sabotage the competitors and ask Gilgamesh to help. When attacked by Godbert Manderville, Ultros is revealed to be helping Avila with Typhon. Once the deception of Avila's Tempest Blade is exposed, Ultros convinces Dour to let him and Typhon fight the adventurer in the Dragon's Neck arena. After losing, Ultros is present at the award ceremony before he and Gilgamesh are sent flying by Typhon's wind. Ultros and Typhon are described as being Voidsent summoned by the Thaumaturge Guild's experiments.
- 奥尔特罗斯使用了他在《最终幻想13》续篇中的模型，在版本 2.4中的调查员支线任务中出现，于菲厄盖斯[译注 1]的斗技场中，充当达沃·梅斗[译注 2]的接待员。他尝试恶意攻击对手，并向吉尔伽美什寻求帮助。当受到戈德伯特·曼德维尔攻击后，奥尔特罗斯被揭露与提丰一起帮助阿薇拉。当阿薇拉掩人耳目的“剑风”[译注 3]被暴露后，奥尔特罗斯说服达沃·梅斗让他与提丰在龙颈斗技场[译注 4]内与冒险者战斗。在失败后，奥尔特罗斯出现在颁奖仪式上，直到他与吉尔伽美什被提丰的风给吹走。奥尔特罗斯与提丰被描述为是在咒术师行会的试验中从虚无界召唤来的妖异。

- Ultros made a guest appearance during the 2017 Moonfire Faire, where he appeared in the event FATE "The Summer of Ultros." Adventurers must subdue him before he can harass the beachgoers. Upon defeat, he promises he'll be good and spends a few in-game hours leering at beach girls from a distance before returning to the sea.
- Ultros makes another appearance at the Sigmascape v3.0 as an add during the Guardian fight.

- In Greek mythology, Orthrus or Orthus was, according to the mythographer Apollodorus, a two-headed dog who guarded Geryon's cattle and was killed by Heracles. He was the offspring of the monsters Echidna and Typhon, and the brother of Cerberus, who was also a multi-headed guard dog.
- The Orthros of Final Fantasy has no connection with the mythical Orthros, save for their link to Typhon, which in the Greek myth was the father of Orthros and Cerberus. The likely reason Orthros is an octopus is given in the book for Final Fantasy Origins: Final Fantasy VI. An octopus was the main character in the first game Square ever made, and during the production of Final Fantasy VI, a programmer told illustrator Yoshitaka Amano and producer Hironobu Sakaguchi that the octopus they were designing reminded him of a purple octopus toy he had as a child named Orthros. The Orthrus spelling is also the name of a genus of jumping spider, another eight-limbed creature.
- 最终幻想里的奥尔特罗斯与神话中的奥特休斯并没有关联，他们唯一的共同点是与提丰都有关联，堤丰在希腊神话中是奥特休斯与刻耳柏洛斯的父亲。奥尔特罗斯之所以会是一只章鱼的可能原因在有关 Final Fantasy Origins: Final Fantasy VI 的书中被给出了。在Square曾经制作的第一款游戏中，主要人物中有一只章鱼，而在《最终幻想6》的的制作过程中，一位程序员告诉插画员天野喜孝与制作人坂口博信，他们设计的章鱼使他想起了他童年时拥有的一个名为“奥尔特罗斯”的紫色章鱼玩具。Orthrus也是一种跳蛛属的拼写，这也是一种与八脚有关的生物[译注 6]。
- Ultros's CollectaCard in Theatrhythm Final Fantasy addresses the character's recurring naming discrepancy:
- "Though his name has at times been mixed up with that of a certain two-headed dog of legend, Ultros is quite definitely just an octopus with no sense of propriety for women. He is quite strong, though."
- Square Enix's Eorzea Cafe serves a food item called "Marinated Orthros ~Genovese style~" with a description that translates to: Orthros, lover of many. Regretfully defeated and then marinated. However, even after being cooked, his mind still continues to be filled with thoughts of his "bro"...
- Square Enix的艾欧泽亚主题咖啡厅中，一道名为“腌制奥尔特罗斯~热那亚风味 ~”的菜肴带有的描述翻译如下：奥尔特罗斯，许多人的挚爱。很抱歉落败了，并因此被腌制。然而，即使已经被煮熟了，他的脑中仍然充满了对他“兄弟”[译注 7]的思念...
