Area bosses

Area Bosses are boss monsters which spawn on their own in a hunting area near a town. They are themed after the monsters they spawn with in that town. These bosses are typically weaker than those found in Party Quests or summoned, however this is not always the case. Most players are capable of soloing an area boss when they are equal in level with it.

For the Availability of Area Bosses, please check the content availability tables.

Major Bosses

These are the most powerful bosses in the game, and the most significant to the lore of the Maple World. All of them drop skills that are crucial to 4th job characters, and several give special items to prove that a player has conquered it. Their release typical marks a major step forward in a version's history.

MS Mob Icon Pianus.pngPianus

Pianus is found at the Cave of Pianus through 'A Grave of a Wrecked Ship' at Aqua Dungeon. Go to a glowing doorway to enter 'A Dangerous Cave', which, at the end, you'll find Pianus, who spawns every 36 and 24 hours. The Right Pianus spawns every 24 hours, while his reflection, the weaker Left Pianus, is 36. MapleSEA recently released this description of Pianus:

"A heavenly fish who had once enjoyed the life of immortality, was banished into the world of MapleStory for eating up his friend simply because he was famished. Thrown into The Cave of Pianus, he is all alone, by himself, and would occasionally project an image of himself to relieve his loneliness."

Pianus can attack with a laser beam and a 10 ton metal block. He is also known as the Doom Flounder. To prove that a player has conquered Pianus, they can perform a quest which grants them the Red Musketeer Cape.

Found at the end of the Guild Quest located in Perion-Sharenian. It's a demon that Sharen the 3rd, who ruled over the great empire of Sharenian in the highlands, summoned in order to protect the legendary jewel Rubian.

Centuries later, the ruins of Sharenian were discovered by humans, and when intruders went in to explore the ruins, they accidentally touched the Rubian, causing demon Ergoth, who had laid dormant for a long time, to awake.

MS Mob Icon Papulatus Clock.pngPapulatus

The Papulatus, and related forms, are all located in the last map of Ludibrium's dungeon, The Clock Tower, called "Ludibrium: Deep Inside of Clock Tower". MapleSEA recently released this description of Papulatus:

"Papulatus Clock Boss is an evil monster who hogs the Time Sphere and likes to steal the power in Ludibrium. With him around in the Clock Tower, Ludibrium will never enjoy the peace and harmony they once had."

Papulatus is a monster from the Maple World's parallel dimension. It entered through a crack in the dimension caused by Ludibrium's failing power supply, the Time Sphere, with several other monsters. The Time Sphere is made by mixing Tachions and Mysterious Powder, which is Papulatus' energy source as well. Papulatus contaminates these Tachions, draining the Time Sphere's power. Some of the other monsters that followed Papulatus through the Crack are carrying pieces of it, which are needed to seal the hole. Once the pieces have been acquired from these monsters, namely Gigantic Spirit Viking and Grim Phantom Watch, the crack can be repaired, causing Papulatus' escape route to be blocked and driving it into the open. Once this occurs, players can finally confront the monster that is disturbing the Maple World and end its leeching. However, once Papulatus has been defeated, there is still one last task: Eliminating the evil force that still remains in the contaminated Tachions. The only thing that can destroy such a dark aura is the fires of El Nath's volcanoes, so the Dark Tachions must be taken there. This force is what has caused the normally innocent toys of Ludibrium to transform into monsters. After all this, Ludus Lake will finally be able to return to normal.

Approach Mr. Bouffon at Path of Time in Ludibrium. He will let you know how to get to Papulatus Clock Boss. Papulatus attack with lightning bolts, a blast of flame and by chances turn players HP and MP to 1. It can also dispel everyone on the map, causing deadly situations for low hp classes. Upon completing Mr. Bouffon's quest, a player can obtain the Ludibrium cape as proof they have slain Papulatus.

MS Mob Icon Zakum.pngZakum

Zakum, one of the most powerful bosses released in most versions of MapleStory, Is located in the Dead Mines of El Nath, one of the main dungeons. Highly coveted by those above Level 100 for the exclusive Zakum Helmet. In a 4th Job Advancement quest, it tells the story of Zakum's rise.

Zakum was a spirit sealed in a tree deep in the mines of El Nath's volcano. A mining town that once existed nearby eventually discovered this tree. At the time, it had no malevolent notions, but the greed of the miners corrupted it. As the spirit was corrupted, it grew smarter, and finally became capable of controlling the town's populace. It forced them to build an enormous statue in tribute to it. The now evil spirit of Zakum possessed the statue, subjugated all the humans and eventually killed everyone in the town. Zakum now rests deep in the lava caves, waiting for powerful players to challenge his might.

MS Mob Icon Horned Tail.pngHorntail

Horntail is a powerful boss in the game for most versions. It drops a powerful necklace called the Horntail Necklace, which adds massive amounts to every stat. Located deep in Leafre, in the Cave of Life. Several Leafre quests reveal what has occurred to bring Horntail into battle.

The forest of Leafre is protected by the Nine Spirits dragon, a kind and gentle creature. The Nine Spirits Dragon has set up a barrier which shields the forest from evil. Horntail, a power hungry dragon, began to rebel against the Nine Spirits rule, and started uniting the evil dragons. This group of evil dragons began their assault on the town, almost entirely wiping out the Dragon Squad, a team of human fighters sent to defeat Horntail. This was a horribly disgraceful action coming from a Dragon. During this battle, Horntail gravely injured the old Nine Spirits, and took the egg of the Nine Spirits Dragon. He then hid out deep in the Cave of Life to recover his strength. Horntail's minions still overtook the Dragon Forest in Leafre. His evil power is so great that it has even gained the power to corrupt the other monsters, turning them pitch black. Now, the strongest players must band together to defeat this cruel dragon, save the Nine Spirits Dragon Egg, and protect Leafre once and for all.

MS Mob Icon Von Leon.pngVon Leon

Von Leon was once the king of an El Nathian village, and ruled alongside his wife Ifia. A century ago, Ifia was murdered, and he found a Cygnus Knight crest on her body, making him believe they murdered her. With this, he seeked revenge, and joined the Black Mage, who set up the murder to make it look like the Cygnus Knights did it. When the Black Mage was sealed, Von Leon cast a spell to kill everyone in his village and to conceal his cancel until the Black Mage's return. Most of the villagers, now ghosts, could not rest in peace due to Von Leon turning into a villain, and decided it was time for his demise. His dead wife, Ifia, tries to talk to Von Leon but he does not see her because he became too much of a villain.

Event Bosses

Fake Bosses

As part of an event in Korean MapleStory and Global MapleStory, false bosses were implemented on some maps for a short time.

These bosses are significantly weaker and have less HP than their normal counterparts, most doing a mere 1 point of damage to high-leveled characters. They also drop several cakes upon defeat.
