Drax’s family

It hasn’t come up in a while but, without spoiling anything, it’s good to remember that Drax lost his family many years ago. His wife, Ovette, and his daughter Kamaria were killed on their home planet of Kylos by Ronan the Accuser, who was working for Thanos. Later, Drax’s rage over losing his family is what drove him to become “Drax the Destroyer.” And though he’s since gotten revenge on both Ronan (directly) and Thanos (indirectly), he still carries that pain with him.
