* AdaptationDisplacement: For most people, Onslaught is better known through his appearance as the end boss in ''VideoGame/MarvelVsCapcomClashOfSuperHeroes''.
* DorkAge: Took place during quite a few, including ''ComicBook/TheCloneSaga'' (and was the reason for the final delay for the end of it), the aftermath of ''ComicBook/TheCrossing'', Thor being depowered by Creator/WarrenEllis, noseless and bone-claw Wolverine, and had some of Joseph's earliest appearances. While it mercy-killed the stuff caused by ''The Crossing'' and Ellis' ''Thor'' run, it also led into ''ComicBook/HeroesReborn'', but between this, ''Heroes Reborn'', and ''Comicbook/HeroesReturn'', a lot of what happened in ''The Crossing'' and Thor's depowering were undone.
* SugarWiki/HeartwarmingMoments: When Bishop apologizes to Gambit for mistakingly believing him to be a traitor.
* SugarWiki/MomentOfAwesome: ''Marvel Universe: Onslaught'' was pretty damn epic.
* TheyWastedAPerfectlyGoodCharacter: A villain born out Xavier's and Magneto's mentality sounds like he could have been an interesting character, but sadly descended into a GenericDoomsdayVillain.
* VillainDecay: In ''Onslaught Reborn''.
