Personality
Vander Decken has been described as a bandit of the sea floor, and the residents of Fishman Island feared him for years. He is attracted to the Mermaid Princess, sending her letters, packages, and even threatening marriage proposals. He is rather obsessive about getting the princess to marry him, going so far as to say she can either marry him or die. He has been threatening her for ten years. He is the reason why the three princes raised an army. He also has a desire for treasure as he does not approve his angler fish of eating ships before he can collect the ships' treasure.

He is also very formal, as shown when he introduced himself to Hordy Jones.

Abilities and Powers
Like his predecessors, he has shown an apparent unique ability to move underwater without a coating. He also appears to easily control at least two gigantic sea creatures, although whether Wadatsumi and Ankoro were tamed by him or his ancestors is not yet confirmed.

Devil Fruit
Mato mato no mi

He has the ability to target anyone he wants, simply by throwing something. He uses this power to threaten Shirahoshi by sending weapons to kill her. he is the only known Fishman to have a devil fruit powers. with his powers he has the ability to target long range and give it a greater force. The reason why princess Shirahoshi is locked up in her room is because of this power.

History
Eventually, Vander Decken IX became captain of the Flying Dutchman and formed a crew which included Wadatsumi and Ankoro, hunting down coated ships that tried to descend to Fishman Island for their treasure.

He also started to send letters, which became packages, which became threatening marriage proposals to the Mermaid Princess. His actions angered Neptune, the Princess' father, which led the Ryugu Kingdom to raise an army against Decken and his crew. Decken was also noted in posters in Fishman Island to be dangerous.

Fishman Island Arc
After many years passed, he encounters the Straw Hat Pirates when his umibozu, Wadatsumi, stops an angler fish from eating the Thousand Sunny. Vander Decken then orders Wadatsumi to attack the Thousand Sunny so he can take their treasure. Unfortunately for him, the kraken, Surume, having been tamed by Luffy, Zoro, and Sanji, intervenes and defeats the Umibozu. Decken then yells at Wadatsumi to get up and retaliate, but is informed by one of his crewmates that the undersea volcano is about to erupt.

With the volcano starting to erupt, he orders Ankoro and Wadatsumi to pull the Flying Dutchman away from the approaching magma, saying that his business with the Straw Hat Pirates isn't finished.

He is later seen with Wadatsumi and Ankoro, asking Wadatsumi how long it has been since he has started proposing to the Princess Shirahoshi. Wadatsumi replies that it has been ten years. He blames Neptune, saying he thinks the king has a politically motivated wedding planned for her. He comments on how painful it is, as he thinks they are both in love (though really it is just him). He then brandishes a large axe with a rose painted on it, saying he will present her with it. He then throws it, but the axe doubles back and takes out the mast of his ship, causing one of his crew members to tell him he missed. Vander Decken then crosses his arms, saying he never misses, he thinks. He then declares his love for Shirahoshi by saying that he would never find a woman like her. He says it is good if her love unites them, but that she cannot live her life with another man, as he will kill her if she does. He declares she must pledge his love to him or die, saying her fate is either marriage or death.

Later, he's seen reaching Noah, where he meets Hody Jones and his crew. He and Jones make an alliance, wanting to end Neptune's reign, considered too weak for leading the sea people. Because of the Devil Fruit weakness, Vander Decken uses a cloat to walk under water and, when shaking hands with Jones, he wears a glove in order to prevent contact with sea water.
