A boss is a powerful, usually unique monster that is fought to accomplish an objective, be it the advancement or completion of a quest or minigame, or as part of a team player versus monster event. Many quests feature boss fights at their climaxes; such bosses are often the main antagonists of the quests or quest series, or are somehow related to the main antagonist(s). Some monsters that are commonly referred to as bosses are very powerful monsters that are commonly fought by teams of players in search of highly valuable drops. Many bosses have extremely high combat levels, and all of the strongest monsters in the game are bosses.
Dwarf multicannons often cannot be set up in the areas of many bosses. Others may have different restrictions; for example, only black equipment may be used to fight the tormented wraith, and Prayer cannot be used during the fights with the final bosses of Recipe for Disaster.

These are the most powerful bosses that do not share a lair or dungeon with other bosses. These are amongst the most powerful creatures in RuneScape and, with the exception of the Queen Black Dragon, Araxxor and Araxxi, and Telos, are mostly killed with a team.

God Wars DungeonEdit
For each warring deity in the God Wars Dungeon, there is a very powerful leader commonly referred to as a 'general'. Each general also has three bodyguards, one of which uses each style of combat: Melee, Magic and Ranged (with the exception of Nex having four bodyguards and they all use Magic). In addition to the 60 Strength or 60 Agility required to enter the God Wars Dungeon, each general's encampment has further requirements to enter.
|Name||Level||Entry Requirement||Description||Attack Style||Slayer category|
|Nex||1001||70 Agility||Nex is the leader of the Zarosian army trapped within the God Wars Dungeon by the forces of Saradomin, Zamorak, Bandos and Armadyl. She has a number of immensely powerful attacks in her arsenal, some of which can hit up to 6848 damage. Rather than following the trend of other God Wars Dungeon bosses and having three bodyguards, Nex is assisted by four mages, each of which represents one of the elements of the Ancient Magicks. Reaching her requires assembling a key to bypass the frozen door, the four pieces of which may be dropped within the monsters of the Saradominist, Zamorakian, Bandosian and Armadylean encampments. Thus, Nex effectively has all of the requirements of the other God Wars Dungeon bosses to reach.

Heart of GielinorEdit
Heart of Gielinor, is the sequel of God Wars Dungeon, set in the Sixth Age. Like God Wars Dungeon, it also features four warring factions, each with an unique and powerful boss. The warring factions are the armies of Sliske, Zamorak, Zaros and Seren — the four entities from Freneskae. Similarly to the God Wars Dungeon, each faction requires level 80 in a specific skill. All those bosses drop dormant Anima Core equipment, which can be combined with crests of all Gods to obtain God-specific armor, and level 85 weapons, which provide accuracy and damage in differing tiers.
|Name||Level||Entry Requirement||Description||Attack Style|

They are Avernic demons who have been in Zamorakian service since the Gielinorian God Wars. The player simultaneously fights both Nymora and Amaryss, thus needing to expect damage from two sides.
