  Character description
  Gendry was conceived and born in King's Landing after Robert's Rebellion ended and is one of sixteen (twenty in the television series) bastard children of King Robert Baratheon.  He is fourteen years old when introduced in the first book, and is portrayed as tall and very muscled, having blue eyes and thick black hair, very similar to his biological father Robert in youth.  He also looks hauntingly like a younger version of Renly Baratheon, though with a squarer jaw, bushier brows and tangled hair, but resembles his biological uncle enough that for a moment Brienne of Tarth almost mistook him for the deceased Renly. Gendry is an intelligent boy despite being born into poverty, but is also stubborn, sullen, suspicious, easily confused and shy around women, and Arya Stark commented that he looks pained when he tries to think.
  Gendry is a biological (though illegitimate) first cousin to Shireen Baratheon, the heiress of House Baratheon on Dragonstone and King Stannis' claim to the Iron Throne. Through Robert's grandmother Princess Rhaelle Targaryen, King Aegon V's youngest daughter, he is actually also a third cousin (once removed) to Rhaegar, Viserys and Daenerys Targaryen.
