|This article is about eagle companion of Kassandra. For other uses, see Ikaros.|
In the 440s BCE, a hatchling Ikaros was found by a young Kassandra after she was thrown down from the top of Mount Taygetos by her father Nikolaos. Ikaros afterwards accompanied Kassandra as she fled from Sparta and ended up on Kephallonia. Forming a close bond, Ikaros often operated alongside Kassandra during her time as a misthios, gaining her nickname and fame as the "Eagle Bearer".
Ikaros' reconnaissance ability was of great help to Kassandra during her travels. In addition to this, Ikaros helped her also by attacking those who had targeted her, and by distracting Kassandra's human enemies at her bidding.
If Kassandra was hunting, Ikaros would occasionally swoop down to get a kill of his own.
- Ikaros functions mostly the same as Senu from Assassin's Creed: Origins; the major difference is that Ikaros can hurt and even kill humans on his own, unlike Senu.
- Ikaros may be named after Ikaros, who flew too close to the sun and fell to his death in Greek mythology.
- According to numerous individuals, Ikaros is the "eagle of Zeus", giving Kassandra her epithet of 'Eagle Bearer'.
- The life expectancy of a Golden Eagle is 30 years, if Ikaros had been watching over Kassandra since she was born, he would be nearing the end of his life by 422 BCE.
- By the time of the modern day, when Kassandra meets Layla in Atlantis, she mentions that Ikaros has long since passed away.
- In a loadscreen blurb, it's mentioned how Ikaros had been a "part of (Kassandra's) family ever since Sparta."
- In the game, Ikaros was previously an eagle companion of the philosopher Pythagoras, who sent him to watch over Kassandra.
