* Mark's consecutive Badass Boasts to Conquest:
-->'''(after Conquest makes his introduction)''': Maybe you do not understand. I have caused all the destruction you see around you. The lives lost here are a direct result of my actions. I can't describe the guilt, the shame... and most importantly the anger that I am feeling right now. All I have thought about- the only thing I've wanted since all of this has happened...was to hit something as hard as I can.
-->'''(after Conquest "kills" Eve)''': I don't care how strong you are. I don't care how fast you are. I can see the future...you don't live to see tomorrow.
* There's a good reason Viltrumites don't use cybernetic parts: [[http://fc06.deviantart.net/fs49/f/2009/199/4/6/Page_from_Invincible_64_by_WyA.jpg this.]] You're welcome.
* Allen gets horribly wounded and hospitalized by a pair of Viltrumites. But it turns out that his powers work on the premise that whatever doesn't kill him makes him stronger... much stronger. The next Viltrumite to attack him received a very, very unpleasant surprise.
* Angstrom Levy get a villainous one in Issue #60, ''Invincible War,'' attacking the planet with a small army of AlternateUniverse Invincibles. Just about every superhero on the planet has to contribute in order to save the world from utter destruction.
* Also from Invincible War, Rex Splode's HeroicSacrifice. The only thing getting in the way of the badassery that is charging his own skeleton to explode when finally out of options is the fact that this long lasting (if unpopular in-universe) character is the fact that it happens so hastily and doesn't hold much impact due to the 'Event Comic In One Issue' nature of the book.
* A somewhat minor one for the author Kirkman. After the Viltrumite War, Mark returns home to find that Eve has gained a significant bit of weight since he left. Mark clearly doesn't mind at all, and while she does seem to drop a few pounds, later on, the weight gain itself is not treated like a problem. Kudos to Kirkman for trying something so few comics would.
* The series, in general, has made quite an impact at Image, with various spin-offs and a much brighter tone than the infamous NinetiesAntiHero days, while still keeping excellent storytelling and the frequent gruesome imagery.
* The showdown between [[spoiler:Thragg and Battle Beast]] (pictured above) goes on for DAYS, showing up as splash pages during unrelated issues while they continue fighting.
** The buildup to the fight was awesome in and of itself: [[spoiler: Battle Beast lands on Thraxa knowing that the former Grand Regent of the Viltrumites is there, and when Thragg makes his appearance, BB's girlfriend unleashes a horde of Ragnars upon him...''which BB then slaughters just so he can have Thragg all to himself!'' Battle Beast then [[HonorBeforeReason slices his own stomach open to put himself on even footing with Thragg]], followed by the two exchanging [[BadassBoast badass boasts]] before finally going at it.]]
** [[spoiler:Thragg's]] resolve to win is also worth mentioning. Failure is just NOT an option for this guy, especially when it concerns the survival of his race, which now includes [[spoiler:the dozens of hybrid children he's already sired through the Thraxans.]]
-->'''[[spoiler:Battle Beast]]''': I sense my victory drawing near!
-->'''[[spoiler:Thragg]]''': NO! You fight for glory, while I fight for the very existence of my people, whom I have sworn to protect at all costs! I WILL NOT FALL!
** The last time the two encountered one other, [[spoiler:Thragg]] took [[spoiler:Battle Beast]] down in one move. Here, the two are evenly matched throughout the entire fight, showcasing their sheer skill and brutality as they tear into each other for days on end.
** After several days of beating the shit out of each other, [[spoiler:their fight comes to a close when Thragg [[AndShowItToYou rips BB's heart out and crushes it in his hand]] while declaring "IT'S DONE"!]]
*** Look at how badly injured [[spoiler:Thragg]] is during the above moment: [[spoiler: his eye has been gouged out, his skull split open, his innards are showing thanks to a large gash he received from the Ragnars before the fight even started, one of his arms is mangled, his body is littered with numerous other lacerations, is bleeding profusely, and yet he ''still'' managed to overcome his foe. Strongest of the Viltrumites indeed.]]
** And to top it all off, [[spoiler: Thragg [[CreepySouvenir skinned Battle Beast's corpse and then used his hide to make a new robe that he now wears as a trophy.]]]]
