Fighting the Hood[]

In February 2013, Barrera was hired by China White to kill Malcolm Merlyn, under the orders of Moira Queen. The moment Barrera arrived in Starling City's airport with his helicopter, he talked with Chien over the phone, wanting half of his payment now. Once Chien transferred $500,000 into his account, Barrera assured her that he would kill Merlyn. Just then, he was confronted by the Hood. After a brief fight, the Hood killed Barrera by thrusting an arrow into his chest.

Felicity Smoak identified Barrera's target by hacking his phone.[2]
