Mero is a character who appears in the third season episode "Second Sons". He is played by Mark Killeen.

Mero is a Braavosi sellsword known as the Titan's Bastard and one of the captains of the Second Sons.

Season 3
Mero is a captain of the company of sellswords known as the Second Sons. Along with his co-captain Prendahl na Ghezn and a lieutenant Daario Naharis he meets Daenerys in her tent outside Yunkai but snubs her offer to fight for her on the premise that the Second Sons already had a contract with Yunkai. After aiming several lewd insults at Daenerys and groping Missandei, he leads the Second Sons out of her tent with a barrel of wine as a token of her willingness to work with them. Despite putting up with his insults while in his presence, the moment he is gone Daenerys orders Ser Barristan Selmy to kill Mero first if their armies come to battle, to which Barristan replies he will be glad to do so.

Mero is next seen back at his camp discussing Daenerys with Daario and Prendahl while groping a Yunkish prostitute on his lap. They eventually decide to assassinate her. Mero gives the Yunkish slave three coins to hand out at random to the three Second Sons to decide which of them should do the deed – Daario winds up with the Braavosi coin, leaving the task to him. Later that night, Daario enters Daenerys's tent and produces Mero's head, along with that of Prendahl, and pledges the Second Sons to her cause.

In the books
In the A Song of Ice and Fire novels, Mero's background is the same. He is described as having pale green eyes and a bushy red beard. He is the captain of the Second Sons, though under his leadership the Second Sons' reputation has fallen to the point where none of the Free Cities will hire him any longer.

In the books, as the Second Sons are a separate company from the Stormcrows – to which Daario Naharis and Prendahl na Ghezn belong – Mero is not killed by Daario, instead he flees when the Stormcrows go over to Daenerys and attack the Yunkish forces.
