Who Are the Guardians of the Galaxy?

Professional wrestler Dave Bautista was chosen to portray Drax the Destroyer, a powerful alien being once known as the human Arthur Douglas. Arthur's spirit is captured by Titan god Kronos, and the human is turned into a superstrong creature who is programmed to kill Thanos (the supervillain who raised Gamora, played by Zoe Saldana). Drax can conjure blasts of cosmic energy and wield super strength and agility, as well as sense the presence of Thanos.

"He's full of rage and honor. He's very literal," said Dave.
