In October 2007, his autobiography Batista Unleashed, was released.[15] In an interview about the book, Batista claims "I didn't want to tell my story unless it was honest," and that "you have to go through three sets of lawyers: Simon & Schuster lawyers, WWE lawyers, my lawyers. Everything now being the way it is, you can be sued for the simplest thing."[130] One source of controversy was the mentioning of Chris Benoit, who was almost completely removed due to the Chris Benoit double murder and suicide. Batista responded saying "I loved the guy. I despise what he did, but that doesn't erase him from my life. I fought to keep him in there and glad they did."[130] When asked about his ex-wife, Angie, he says "[we] have really become close again, which we really haven't been in years. I really learned a lot about her, and she learned a lot about me from reading the book. She actually saw things from a different perspective from reading the book. So that was definitely therapeutic."
He has numerous tattoos, including a large Chinese dragon on his back, red Kanji lettering on his upper left biceps which says "Angel" in tribute to his former wife Angie, a signature design on his upper right biceps, and a small Sun on his stomach which encircles his belly button.[131] He also has a tattoo on his arm of the flags of the Philippines and Greece merged into one. While taking time off due to injury in 2009, Batista had both upper arms covered in large, tribal style tattoos, including the word "soldier" on his right biceps.
