Arthur Curry / Aquaman

Even though Aquaman may not have the same level of financial success as Reed Richards, he comes from a long line of wealthy ancestors. Since the oceans are Aquaman’s domain, he exercises authority over approximately 70 percent of the planet. In addition to his royal title, Aquaman has access to millions of shipwrecks located all over the ocean. These shipwrecks are home to treasure worth billions of dollars, which Aquaman can access at any moment along with anything else of value that is located in the ocean. As a result of this, Aquaman has significantly surpassed Batman in terms of wealth, becoming the richest superhero in the DC Universe. After making his debut in the DC Extended Universe with a brief appearance in Batman v Superman: Dawn of Justice, Aquaman went on to have a supporting role in Justice League and then headline his own picture, Aquaman.
