Okay, let's break down these points about Overlord and the "Dragon Emperor" (龍帝, Róngdì):
1. "龍帝 (Dragon Emperor) is a Hidden Boss:"
"Accuracy:" This is generally considered "correct" based on the Light Novels and Manga.
"Explanation:" The Dragon Emperor is not an antagonist the player (Naruto) directly fights. It's a powerful, ancient dragon entity that resides within the Overlord's true form (the "Sword of Evil" / 悪しき剣, Akishiki no Ken). Its existence is only revealed gradually, primarily through Rudeus's dreams and flashbacks, and later through specific events like the dragon attack on the capital and the confrontation with the otherworldly being Medusa. It's a fundamental part of Overlord's power but remains largely unseen and unheard-of by most characters within the story.
2. "Dragon Emperor's Power is Stronger than the Skeleton King (骨王, Kotsukami):"
"Accuracy:" This is "highly likely and strongly implied", although not always explicitly stated in a direct power comparison.
"Explanation:"
"Kotsukami:" Is the most powerful physical being in the Lower Layer Dungeons and arguably the strongest individual NPC under Overlord's command. His power is immense, especially in
龙帝是何许人也？从名字也能看出，龙帝是龙族数万年来亘古不变的最强者。很多观众认为龙帝不过是渣渣，当年被八欲王吊打，龙族十倍代价未能战胜八欲王。实际上龙族十换一这个设定是web版的，web没有龙帝这个角色。
web版的龙族很弱，玩家却强的离谱。例如世界冠军，web版中6个足以碾压50多个顶级法师“世界灾厄”。而文库中世界冠军只有三名百级玩家的战力，再遇到50多名世界灾厄的话，怕是要被秒杀。文库的龙帝并未提及已死亡，龙帝可是和穿越事件有着直接的联系。
骨王能战胜朽棺龙王，是凭借着克制的优势。换作世界冠军来打，没有把握战胜朽棺。仅仅是120万僵尸，就能消耗掉塔其米大量的体力。况且外传的骨王持有权杖，并召唤了游戏中不可能出现的5只黑山羊幼仔。
根据丸山公布的等级来看，龙帝的等级在95级的朽棺之上，是异世界的隐藏BOSS。朽棺虽没有百级，但属性凌驾于百级的骨王。朽棺只是拥有王者水平，但操作如同青铜。若龙帝达到百级，其属性至少是骨王的2倍以上。白金龙王天克骨王，而龙帝比所有真龙王都强，实力自然也比骨王强。
目前已知龙帝设定大于朽棺龙王，这已经不是几名百级玩家就能单刷的程度。很明显，龙帝的实力甚至在世界冠军之上，拥有抵挡世界道具的特殊职业。龙帝这个隐藏BOSS，大概会在完结时登场。
