Onegesius () was a powerful Hunnic logades (minister) who supposedly held power second only to Attila the Hun. According to Priscus he "seated on a chair to the right of the king" i.e. Attila. History Priscus, who was on a mission to Attila in 448 or 449 AD, says that Onegesius lived in the same very populous village Attila resided. He recounts: According to Onegesius's order Priscus and Maximinus were greeted by his wife at his compound. That the honour and respect of his supporters were important to Attila is shown from Priscus testimony: Priscus recounts a rare story of a Greek he encountered in the village, and who managed to get freedom from the Huns, but decided to live among them: Onegesius and his brother Skottas were persons of special interest to the Romans in their failed plot to assassinate Attila in 448 or 449 AD, which included Chrysaphius and Hun Edeco, but Onegesius was most of the time away.

So Attila did, Kardach stayed with his tribe or clan in own territory, while the rest of the Akatziroi became subjected to Attila. He "desired to make his eldest son their king, and so sent Onegesios to do it". Maximinus, not knowing that the plot failed, tried to bribe Onegesius, "that the time has come for Onegesios to have greater fame among men, if he would go
