Heroes Ren (voiced by George Newbern) - The prince of the once-grand kingdom of Octopon and the main protagonist of the series. Ren was raised by a lighthouse keeper in the outskirts of his homeland, unaware of his destiny and heritage. He wields the broken sword that belonged to his father in its whole form. By the beginning of the second season, he freed one half of the planet from the Dark Water. Niddler (originally voiced by Roddy McDowall in the Dark Water miniseries, later voiced by Frank Welker in the TV series) - A monkey-bird who once belonged to Bloth, until he escaped by aiding Ren's own escape from the pirate captain. He hails from the island of Pandawa. He is usually depicted as a little greedy and constantly ravenous for food, his favorite food being minga melons, but he likes Ren, and his ability to fly often comes in handy. Tula (voiced by Jodi Benson) - She is an ecomancer with the ability to control the elements and biological life, both sentient and non-sentient, as well as a natural affinity towards nature and animals. She is headstrong and often flusters Ioz. She is introduced as being a simple barmaid, but she stows aboard Ren and Ioz's ship, claiming she "wanted to get away from the drudgery of life on land." It's soon revealed that she's a character with many secrets. Ioz (voiced by Héctor Elizondo) - A rogue and pirate, he joins up with Ren initially for the promise of treasure. Throughout the seasons, his character matures and he becomes fond of Ren and his idealism, evolving into a protective brotherly figure to him and often risking his life for Ren and the quest for the Treasures. However, he still continues his attempts at getting rich quickly but is mostly unsuccessful. Ioz also has a younger sister named Solia, who appears in the series. Like Niddler, he originally worked for Bloth, but "it ended ugly" according to him. Zoolie (voiced by Richard Gautier) - A jolly, redheaded rogue who runs a gamehouse in Janda-Town. He and Ioz crewed together on Bloth's ship, the Maelstrom. Though not a main character, he does make recurring appearances, by offering advice and assisting Ren and his friends whenever they make port in Janda-Town. Teron (voiced by Dan O'Herlihy) - He is a supreme ecomancer who sprouts roots from his body in order to replenish himself from a portable supply of native soil when he is away from his homeland, Andorus. He is first seen in the series as a prisoner on Bloth's ship, and Bloth uses his power for evil, in turn exhausting the local environment and its positive life-energy. Tula has great respect for him as an ecomancer, and she was sent on a mission to bring him back to Andorus to heal the Dark Water-ravaged island. Villains Bloth (voiced by Brock Peters) - The ox-sized, humanoid pirate captain of the feared pirate ship Maelstrom and one of the primary antagonists of the series. Bloth is after the Thirteen Treasures of Rule to control all the Dark Water in the world, and in effect, Mer itself. He destroyed Primus's fleet seventeen years prior to the timeline of the show, and captured Primus and his aide Avagon, though the seven captains accompanying Primus were able to escape with the Treasures. Bloth has since been hunting them obsessively, and destroying every remnant of the House of Primus just as obsessively, including killing every heir to the throne of Octopon that he could find and ravaging and pillaging the ailing city. He held Primus captive for seventeen years before the old man escaped back to Octopon and to Ren. Upon learning that Primus has a son, he transferred his fanatical hatred of Primus to Ren. Bloth began to hunt the boy across the twenty seas of Mer in order to capture the Treasures and to kill Ren and the house of Primus. In the second season, he makes an uncertain and untrusting alliance with Morpho, a major agent of the Dark Dweller. Mantus (voiced by Peter Cullen) - Bloth's second-in-command. He offers his cool and calculating personality as a battle strategist for Bloth's fleet. Konk (voiced by Tim Curry) - A short, fat pirate who works for Bloth. He lost his leg thanks to a close encounter with his master's ferocious pet the Constrictus. For a long time, Konk was the only one to ever survive being thrown to the monster. Although not particularly smart, Konk possesses more bluster than most of Bloth's crew and is always trying to win Bloth's praise. The Lugg Brothers (voiced by Earl Boen and Frank Welker) - Two huge, dimwitted siblings who are members of Bloth's crew. They try to assist Konk, but their stupidity makes them more of a hindrance than anything. They only make appearances as main characters in the first five episodes of the show.
