Drax the Destroyer is a pretty scary guy all on his own, not to mention when he’s teamed up with the rest of the Guardians of the Galaxy. But when it comes to the top enemy on his list, Thanos makes Drax look like a child in comparison. Exacting revenge on the Mad Titan has been Drax’s sole purpose, ever since some pretty dark stuff went down involving his family and home planet.
But as we saw in Avengers: Infinity War, that vengeance was never actually achieved by Drax, although not for a lack of effort. As we saw in Knowhere, amongst The Collector, Gamora, and others, Drax would try to take Thanos’ life while the opportunity presented itself. But it was revealed later to just be a trap set by the Mad Titan to kidnap Gamora because of her knowledge of the Soul Stone’s whereabouts.
That moment, in particular, was talked about in the official audio commentary for the Avengers: Infinity War home release. Director Joe Russo had this to say:
“This is a callback to Drax’s history with Thanos here… His planet was treated the same way as Gamora’s planet. Drax was put on one side, his family was put on the other.”
In Guardians of the Galaxy Vol. 1, there was a scene where Drax held a knife to Gamora’s neck and explained how Ronan the Accuser killed his wife and daughter, Hovat and Kamaria. Drax would later find out that Ronan was being manipulated by Thanos to do his bidding, and then shifted his sights to the bigger threat. This all implies that what happened to Drax’s planet is exactly what went down with Gamora’s homeworld, which makes the two of them and their hate for Thanos much more alike.
What will hopefully connect the dots and smooth out the continuity comes in the form of Captain Marvel’s arrival to the Marvel Cinematic Universe. Ronan the Accuser, will play a big role in the film as will other Kree and Skrull warriors, likely as the movie is set in the past (90’s) prior to the character’s death in Guardians of the Galaxy Vol 1. If Ronan was, in fact, being used as the instrument of destruction to deal death to half of the entire planet’s population, maybe that element will be present in Captain Marvel and help to give that campaign more context to the current happenings in the MCU.
