* Alpha!Church from ''Machinima/RedVsBlue''. At the end of season 6, scarcely even willing to accept that he's an AI instead of a ghost, he goes with Washington to distract the Meta and his many AI, keeping them from killing Wash while Wash sets up an Emp to destroy all of the AI. Wash warns him that when it goes off, Church will die too. His response:
-->'''Church''': When it goes off, I'll be fine. It only affects computers, remember? And I... am a motherfuckin' ghost.
** While technically not an example due to surviving, Epsilon!Church later gets one just as great. Upon realizing that the containment device he chased Tex into is about to collapse, he finally sits down and discusses his painful history with Tex and allows himself to forget her (deleting her from existence) as a way to end her endless suffering. After which, he calmly sits and waits for the end after uttering the following line
-->'''Church''': Okay world, do your fucking worst! 'Cause I sure as hell just did mine
** General Doyle gets one in the Chorus Trilogy, destroying the city reactor, and as such taking out most of the mercenary army fighting his people.
* Ma Ti in ''WebVideo/SuburbanKnights''. After years of being the ButtMonkey of Website/ThatGuyWithTheGlasses, he gives an epic rant at his poor treatment and viciously insults Malachite, having long stopped caring what happens to him. And then it turns out his ring can defeat Malachite, so he goes out in an epic BeamOWar and saves the day.
* WebVideo/ToBoldlyFlee gives us the HeroicSacrifice of WebVideo/TheNostalgiaCritic, as he merges with the Plot Hole to save the universe. By ''punching'' the hole to boot!
-->"Somebody has to merge with it. Somebody has to keep it safe.
* One from the archives of the Wiki/SCPFoundation: a [[CannonFodder D-class unit]], sent in with a video feed to die for recon, apparently singlehandedly fought his way to and destroyed the source of [[http://scp-wiki.wikidot.com/scp-1983 SCP-1983]]... despite being ''unarmed''.
* Some rare metahumans in ''Literature/{{Brennus}}'' are able to 'swan song', burning away their power (and their life) within a few minutes in order to flare their power to new heights.
* The [[SeriesFauxnale Series (Season 7) Finale]] of ''Machinima/ArbyNTheChief'' was intended to go off like this according to [[WordOfGod Jon Graham]] [[spoiler:when [[DrivenToSuicide Arbiter and Master Chief light a Gas Explosion in their apartment killing themselves after realizing there was nothing left for them in the World that didn't revolve around gaming]].]] There are several articles on his blog stating that this was his intentions, but because of [[DarkerAndEdgier how morbid and bleak the show had become by that point]], whether it can be viewed that way or not his way however is debatable.
