If their set at Sonisphere Festival 2011 didn’t alert you to the fact that Slayer are back kicking butt and taking names, then this photo of the Araya family in a dojo in full combat gear should do the trick.

This photo was posted on the SiriusXM Liquid Metal Facebook page and shows Tom Araya, his wife Sandra and his children, Ariel and Tommy. They’re all wearing brown belts which is just one below a black belt.

Do not piss them off.
