Did you know that in Guardians of the Galaxy? Drax can't see things that don't move. When Groot was dancing on Drax's back, Drax looked at him and Groot immediately froze. In that moment, Drax seemed unable to see him, as if Groot had disappeared. Drax realized that living beings who remain still are essentially invisible to him. However, this is a matter of the person's level of perception and attention, and in Drax's view, it makes sense for this to apply to everyone.
What Drax didn't understand is that other species don't share this limitation. That's why, in Avengers: Infinity War, when Gamora and Quill were arguing about the Soul Stone, Drax stood still, believing that no one could see him, since.
