Claim: Akameros, mentioned only once by Theophanes the Confessor, planned to overthrow Empress Irene of Athens.
Evidence: He is mentioned only once, by Theophanes the Confessor, as leading a plot involving the sons of Constantine V (r. 741–775) – the former Caesares Nikephoros and Christopher, and their younger brothers Niketas, Anthimos and Eudokimos – who had been deposed, mutilated by their elder brother, the emperor Leo IV the Khazar (r. 775–780). 
In March 799, Akameros, in collusion with troops from the local theme of Hellas, planned to seize them and declare one of them emperor. 
The plot was foiled however as Irene was informed of it, and the Empress sent a trusted kinsman to Athens: the brothers were blinded and moved to the island of Panormos in the Marmara Sea.
