History Main / LoadBearingBoss

* ''VideoGame/BionicCommando'': "This base will explod in 60 seconds. Evacuate right away."

* In ''Film/ConanTheDestroyer'', when the wizard guarding the key is killed his entire crystal palace crumbles into the lake.

* As Andross is defeated in the ''VideoGame/StarFox'' series, the area in which the fight takes place explodes, forcing the player to escape. In ''VideoGame/StarFox64'', this comes complete with Andross yelling, "If I'm going down I'm TakingYouWithMe!" At this point, [[spoiler:James [=McCloud=]]] shows up and you have to follow him through a maze to get out again -- make a wrong turn and you'll get caught in the explosion.

* In ''Anime/GaoGaiGarFINAL'', when the heroes [[spoiler: [[DropTheHammer use the Goldion Crusher]] to kill Pisa Sol, the whole UNIVERSE falls apart. Thankfully they were in an alternate universe, but still!]]

* In ''Anime/{{Scryed}}'', defeating [[BigBad Kyoji Mujo]] caused the warped base to fall apart. {{Justified|Trope}} since it was being sustained with Kyoji's Alter Power, with him dead, there was nothing supporting it.

%%* Red Falcon in ''VideoGame/{{Contra}} III: The Alien Wars'' and the Relic of Morai in ''VideoGame/{{Contra}}: Shattered Soldier''. Also Master Contra from ''Neo Contra''.

* In ''Manga/OnePiece'', Luffy's final kick against Arlong destroys Arlong Park, the building that they're in. In a filler arc, after Luffy defeats Don Atchino, his Atsu Atsu Fruit powers melt the Atchino family's iceberg base. In the Arlong case, this is because Luffy's final attack was to kick Arlong ''through'' the building; it wasn't so much that the building was destroyed because the boss died, as it was because the boss was smashed through all five floors of it.

* In ''[[VideoGame/{{MUSHA}} M.U.S.H.A.]]'', after defeating the FinalBoss, this message pops up: "You've destroyed their main base! Escape before it blows!" Escape is automatic, but not without showing some damage.

* ''VideoGame/WarioLand''
** Syrup Castle in ''[[VideoGame/WarioLandSuperMarioLand3 1]]'' and ''[[VideoGame/WarioLandII 2]]'' explodes after Captain Syrup is defeated, the first time being explained by a gigantic bomb being placed in the throne room, the second actually sending the boss flying into the horizon.
** Defeating the Golden Diva in ''VideoGame/WarioLand 4'' causes the golden pyramid to sink into the ground as Wario escapes with the treasure.
** There's also Rollanratl in ''[[VideoGame/WarioLandShakeIt The Shake Dimension]]'', who's a literal example. He's actually holding up the boss arena ceiling, and once defeated the roof pretty much falls and crushes him.

* In ''VideoGame/EarthBound'', defeating [[spoiler: the Mani Mani Statue]] ends Moonside and Monotoli's popularity. Averted later with the Starman DX; while the Stonhenge Base isn't destroyed, all the enemies vanish, along with the Sword of Kings, Poo's infamous InfinityPlusOneSword. The instance with Moonside is repeated with Magicant, where [[spoiler: defeating Ness's Nightmare, embodied as the Mani Mani Statue, causes Ness to wake up and Magicant to fade.]] ''VideoGame/{{Mother 3}}'' had Mr. Genetor as a load bearing boss, as his defeat causes the Thunder Tower to shut down and closes the area off forever. [[spoiler: The final boss plays with this. You beat him, nothing happens. Then you go and cause an apocalypse yourself immediately afterwards... sorta. It's more like world rejuvenation.]]

** ''VideoGame/PaperMarioTheThousandYearDoor'' has a load bearing ''ally''. You fight the boss in his fortress and nothing happens, but once you see the AlmostDeadGuy ([[spoiler:actually a computer]]) kick the bucket, the place starts falling apart around you. [[spoiler:He is luckily revived following the FinalBoss fight.]]

*** Lava Piranha does this after he is defeated and the fifth Star Spirit, Misstar, is freed. After the battle, Mt. Lavalava, being an active volcano where he had called his home, starts to erupt, so before the Chapter can officially end, you have to escape the volcano before you're swallowed by lava.

** After the FinalBoss fight with Bowser, the castle begins to explode because the battle was so intense. Bowser's castle explodes ''right then and there in the sky'' while Peach's Castle with Mario and others are saved by the Star Spirits and said castle is brought back to its proper space [[AllYourBaseAreBelongToUs from which Bowser's Castle uprooted it from]].
