Gendry is the bastard son of Robert Baratheon by a tavern girl. He grew up and kept his identity secret and became a blacksmith. Hands of the King, Jon Arryn and Ned Stark, both discovered the truth about Gendry.
Gendry was a member of Yoren‘s party of recruits for The Wall that was joined by the disguised Arya Stark. They were captured by a party of Gold Cloaks looking for Gendry. The Gold Cloaks believed they had killed Robert Baratheon’s bastard son after Arya told them Lommy Greenhands was Gendry and took the rest of the party to Harrenhal.
After escaping from Harrenhal they were captured by the Brotherhood without Banners. Gendry wanted to join them but they sold him to Melisandre. The Red Woman was going to kill Gendry but Ser Davos Seaworth helped him to escape. He returned to Kings Landing and worked as a Blacksmith.
Davos Seaworth sought Gendry out and asked him to join Jon Snow’s party that is to go north of the Wall to catch a wight. Gendry agreed and went north of the Wall. After capturing a wight the party were then pursued by a large army of wights. Jon told Gendry to go back to the Wall and send a raven to Daenerys for help. Gendry then returned to Kings Landing with Sandor Clegane, Davos Seaworth and the captured wight.
Gendry is played by actor Joe Dempsey.
