Mera brought her son to a playdate at Barry and Iris' house. They were the first to arrive and he kept himself busy reading comics and playing with Anissa Pierce and Traya.[3]
While Orin and Mera were busy at the annual conference of city states, Artur played with La'gaan outside, taking on the role of Aquaboy. When the conference broke up, Mera gave Artur a quick kiss before swimming off. Orin explained that she was going to talk to Artur's grandfather, which Artur knew was trouble. Orin then led Artur away from the conference center.[4]
Arthur, Jr., also known as Aquababy, was the youngest member of the Aquaman family. In the iconic story arc "Death of a Prince", he was murdered by Black Manta.
This is his second animated appearance. He appeared as a teenager in Batman: The Brave and the Bold.
