Onyango is a elderly bald man who has piece of metals connected to his temples, with metal cords flowing from them that stop around his jawline. He is relatively short compared to his younger peers and his time in retirement has resulted in Onyango being somewhat unfit. His outfit consists of a dark-coloured cassock, topped by a light overcoat-like garment with a high collar and a skirt-like garment, dark shoes and a pendant with a cross-like symbol as a charm — an outfit, which is shared amongst the Lieutenants of his company.
Despite being forced out of retirement, Onyango is perfectly willing to embrace his old role. Even ready to take part in a photo-shoot for the Firefighter’s Calendar. His relationship with Leonard Burns means that Onyango has a great understanding of what drives the enigmatic and stoic captain, while Burns and the other members of Company 1 appear to hold him in a high regard.
Onyango alongside Company 1 and Leonard, attended the incident involving Shinra Kusakabe's house being on fire.
