I was rereading the Dead King story. Atlan has always been one of my favorite charters since he was introduced in Atlantis Chronicles #5, Never really fond of making him a Villain. But the panel where it was implied that Atlan’s family was killed there wasn’t any bodies. It is possible that one of his children was speared and escaped. Since Atlan was the only Atlantiean that could speak to sea life until Artur Curry. After Watching The Aquaman movie I had this thought, What if Tom Curry is actually a descendant of Atlan who escaped the sinking of Atlantis and lived among the other tribes of the world. And because of this Arthur is a true descendant of Atlan, and that is the real reason why Arthur was able to beat Atlan at the end of the Dead King story.
