Mentioned for the year 1343 by the Byzantine historian Ioannes Kantakuzenos. He was a lieutenant of the Serbian military troops (ἡ στρατιὰ Τριβαλῶν, ἧς ἡγεῖται Μποζίκης τις προσαγορευόμενος καὶ Στέφανος δεύτερος, ἐκ πεζῶν καὶ ἱππέων ἠθροισμένη, πεμφθείη μὲν παρὰ Κράλη ἐπὶ τῷ βλάπτειν βασιλέα). He and his superior commander Mpozikes led the Serbian army consisting of footmen and horsemen, which stayed for the night at Gaurobon on the right bank of the river Vardar. When the Byzantine Emperor Ioannes VI Kantakuzenos with the troops had crossed the river, Mpozikes and Stephanos allegedly without the knowing of the Serbian King Stefan Uroš IV Dušan attacked the troops of Kantakuzenos. The Serbian Stefan Uroš IV Dušan sent him and Mpozikes to Ioannes VI Kantakuzenos in order to be exercised by the jurisdiction of the Byzantine Emperor. Ioannes VI Kantakuzenos reprimanded him in Beroia and released him afterwards.
