Kosses

Mihail Kosses was the Tekfur of Harmankya Castle and the brother of Mari, who was the wife of Turgut Bey. At the start of season 3, he was a great enemy of the Turks. Turgut Bey abducted his sister Mari to get back his alps, who were in Kosses's possession. Kosses went to Osman Bey, the margrave of the borders, and asked him to retrieve Mari from Turgut Bey. Osman Bey visited Turgut Bey's tribe and requested her return. Turgut Bey explained that Kosses had his alps. Osman Bey assured him that the alps would be released. Turgut Bey then returned Mari, and Kosses also returned the alps, but he cut off their fingers so they couldn't hold swords again and killed them while they were returning to their tribe.
Later, Kosses allied with Aya Nikola and Tekfur Rogatus of Bilecik to kill Osman. He caused significant damage to Osman. He sought to strengthen his position by marrying his sister Mari to Aya Nikola. However, Mari did not want this as she was in love with Turgut Bey, and Turgut Bey was in love with her. She asked Turgut for help to escape, and Turgut saved her. Kosses furiously went to Osman Bey and asked for Mari again, but this time Osman said that she was there by her own will and would not be returned. Nikola was furious as his fiancée was abducted on their wedding day. Kosses and Nikola then allied with Vizier Alamshah and abducted Mari from the Kayi Tribe on Turgut and Mari's wedding day. Vizier handed her over to Nikola, who, in his fury, stabbed Mari. However, Turgut saved her again, and then they married.
When Kosses learned that Nikola had stabbed his sister, he became Nikola's enemy and sought revenge as he loved his sister dearly. He allied with Osman Bey to kill Vizier Alamshah and Nikola in Bilecik, but they failed. As a result, Kosses was captured and sent to the Emperor, while Vizier Alamshah captured Osman Bey and planned to execute him. However, soldiers of the Seljuk Empire arrived and took Osman Bey to Konya. On the way to Konya, Geykhatu attacked Osman, killing his alp Goktug and taking Osman and his remaining alps hostage to execute them later. Turgut Bey then saved Kosses on the way to Constantinople and also rescued Osman from Geykhatu.
However, Kosses lost his castle because Nikola took it, and later Gunduz Bey seized it from Nikola with the help of Vizier Alamshah. Kosses then helped Osman Bey in every situation. Later, when Osman Bey executed Vizier Alamshah, he returned Harmankaya Castle to Kosses. Kosses was greatly inspired by Osman Bey and Islamic principles, and he kept contemplating them. He also believed Osman Bey when he said that his brother, Gunduz Bey, did not poison his sister Mari, who was actually poisoned by her aide Cornelia. He also told about the plan to kill Osman Bey in Bilecik Castle and told his children Orhan and Alaeddin was abducted and kept in Bilecik. Osman successfully revealed the truth. Kosses later converted to Islam and served the faith.
