* The intro sequence, which is pretty much an EstablishingCharacterMoment for the entire series. Etna decides that since Laharl won't wake up, she's gonna have to resort to shooting him. He wakes up and asks about the weapons behind her, and Etna defends he's a heavy sleeper. When she tells Laharl that his father died two years ago while he was asleep, he grows angry and asks why she didn't wake him earlier, to which Etna responds "what do you think I've been doing all this time?"
* The Prinnies try their fins at Laharl's challenge to claim the title of the Overlord. They know they're completely outmatched so instead...
-->'''Enemy Prinnies:''' We challenge you to a game of baseball, dood!
-->'''Off-screen Umpire''': Play ball!
-->'''Laharl:''' Etna.
-->'''Etna:''' Yes?
-->'''Laharl:''' [[CurbStompBattle Kill 'em.]]
-->'''Etna:''' Certainly.
** Followed up in ''Disgaea 2'' with bowling, which leads to the most hilariously one-sided battle ever... in ''[[BreatherLevel your]]'' [[BreatherLevel favor]].
* Laharl getting excited over the first [[PokeThePoodle evil deed]] he will commit as an Overlord.
-->'''Laharl:''' You want me to make it rain pepper on Earth so they can't stop sneezing? [[{{Irony}} Or do you want me to give human kids an addictive video game that will deprive them of their sleep?]]
-->'''Etna:''' Uh...no.
* The entirety of '''Captain Gordon, Defender of Earth!'s''' gloriously wacked-out introduction chapter.
* Early in the first game, [[LoveFreak Flonne]] is talking about [[ThePowerOfLove Love and Friendship and Stuff]], and has this exchange with [[LittleMissSnarker Etna]]:
-->'''Etna''': What good is that stuff? Is your head full of flowers or something?\\
'''Flonne''': Yes, I love flowers.\\
'''Etna''': Oh geez... Your head ''IS'' full of flowers.
* With Laharl finding a way to bypass his weakness and Etna rebelling against him, Maderas tries to get the Prinnies to kill her. [[OhCrap He's not happy when he finds out that they exactly don't work for him anymore.]]
-->'''Maderas''': Dammit! Prinnies! Make mincemeat out of her!
-->''-music stops-''
-->'''Prinny Squad''': ...[[ThisIsGonnaSuck Dooooooooooooood]].
* Flonne's entire introduction is one funny moment after another. She enters the castle [[SayingSoundEffectsOutLoud making her own ninja sound effects]]. [[{{Cloudcuckoolander}} She then starts contemplating whether or not it's right to assassinate someone she doesn't know and then starts realizing that killing someone she does know is wrong too]], which is then hilariously lampshaded by Laharl ("Who are you, and why are you in my room talking to yourself?"). And, of course, there's the way she introduces herself to Laharl:
-->'''Flonne''': Nice to meet you! I'm an assassin! ...whoops. [[DidIJustSayThatOutLoud I wasn't supposed to say that]]...
** Becomes even more HilariousInHindsight. Ninjas in Disgaea 4 ''[[TheCloudcuckoolanderWasRight actually say]]'' "Nin nin nin!"
* [[ButtMonkey Mid-boss (Dark Adonis Vyers)?]] [[OOCIsSeriousBusiness Except the very serious parts in the first game,]] he gets dogged by the protagonists in [[http://www.youtube.com/watch?v=O5aThJq4Xvo every]] [[http://www.youtube.com/watch?v=TiWcq6cdqF4 single]] [[http://www.youtube.com/watch?v=OwkEz4DBfzo appearance]].
-->(After being insulted and degraded by [[{{Jerkass}} Laharl]].)
-->'''Vyers''': How dare you! I am the Dark Adonis Vy...
-->'''Laharl''': Who gives a damn about you? Your new name is "Mid-Boss".
-->'''Mid-Boss''': Mi, Mi,M id-Boss!?
** Just to emphasize: The above mid-dialogue name change ''is canon''. The moment Laharl declares Vyers' new name, the game itself ''obeys his command'' and changes it.
* The [[{{Sentai}} Prism Rangers]]. As they are preparing to initiate their TransformationSequence, [[JustShootHim Etna shoots them]].
-->'''Prism Red''': "Bluuueee....Yelllowwww!!!!"
** [[HilariousInHindsight Even funnier when you realize the]] English VA for Laharl [[Creator/BarbaraGoodson is]] [[Series/MightyMorphinPowerRangers Rita Repulsa]].
* In "War of the Netherworld, part 2", everytime someone mentions that Jennifer is about to be modified, Laharl, Etna, and Flonne all imagine a giant robot version of Jennifer stomping around a city until Gordon yells at them for it.
* In Episode 3 of ''Afternoon's'' Etna Mode, Flonne confronts Etna at the Sea of Gehenna...wearing a sentai mask. Calling herself 'Justice Flonne', she swears to defeat Etna, and after being chased off the first time, she comes back, claiming to have powered up. All she does is turn on lights where the mask's eyes are.
-->'''Etna:''' That's it? So your eyes are glowing...?
-->'''Flonne:''' Yes. Now, I can see in the dark.
-->'''Etna:''' Anyone who walks around at night, wearing that mask has gotta be some kind of crazy.
* In Episode 9, when Jennifer and Thursday meet the Disgaea trio. This is Thursday's response when he senses lifeforms approaching:
-->'''Thursday:''' LIFE FORMS ARE APPROACHING. OH $*&% RUN RUN RUN...!
** And in his first scene:
-->'''Thursday:''' GORDON KEEPS STARING AT JENNIFER'S THIGHS. PERVERT - PERVERT - PERVERT!
* Vulcanus' reaction to the contents of a book he finds while sneaking around Laharl's castle;
-->'''Vulcanus:''' This page! This page! All of these pages!
* '''Captain Gordon, Defender of Earth!'s''' ''gloriouse'' introduction.
** And his BadBadActing when he wants to sneak away from Laharl. "LA LA LAAAA!".
* Episode 7's final boss is Aramis' ultimate zombie which Laharl quickly considers TheDreaded. Is it because it was made with the fists of a Dark Karate master, the legs of the fastest demon in the Netherworld, the mind of the sorcerer Mahogany, and the iron body of Hercules? Nope, it's because it has a ''Horse Wiener''.
-->'''Laharl:''' A horse wiener!? Now, THAT's dangerous!
** Increased with the [[GreekChorus Prinny commentary]] in the DS version, when they wonder how one would [[{{Squick}} block it]].
** Even funnier: if you have a good enough Thief, you can ''steal'' the Horse Wiener from the zombie and ''equip'' it yourself!
* Laharl and Flonne meeting Jeniffer, and hearing assumptions that demons are horrible monsters with tentacles, which the two of them take offense to and wonder where she got those ideas from.
* After the boss fight with the previous Defender of the Earth, Flonne is angry at Laharl for not throwing the fight and says he's "The worst" before the ghost cuts her off and says that even though he lost, he can still pass on. Everyone prepares to move on, but Laharl and Etna start to wonder what exactly Flonne was going to call Laharl. Thurday promptly states "Now calculating, now calculating," and as he prepares to give the answer, Flonne does a BigNO and slams him into a wall. Et a replies she's worse than a demon.
* Episode 10. Its plot revolves around ''chasing Mid-Boss [[WhatDoYouMeanItsNotHeinous because he stole their picnic basket]].''
** Upon catching up with Mid-Boss, Gordon, Jennifer, and Thursday do a hammy Power Rangers-esque pose. Flonne gets jealous that they're stealing the show and forces Laharl and Etna to go along, and their presentation is so damn unenthusiastic.
* At the start of chapter 4, read the "something good" as Flonne offering her virginity and the scene CrossesTheLineTwice. [[MetaFic Disgaea Thumbnail Theater]] draws a huge lampshade on it.
-->'''Etna:''' Get your mind out of the gutter, Prince. This ain't no [[HGame hentai game]].
* Kurtis makes his return to help the party when they're blocked by powerful demons in Celestia. It's supposed to be triumphant moment, but it's hard for the characters and the players to take it seriously because he's a green Prinny.
* As the party boards the battleship Gargantua, Gordon surmises that Carter might have ordered for Jennifer's modification. Laharl, Etna, and Flonne then begin to imagine what the modified Jennifer would look like and we're treated to an image of a HumongousMecha Jennifer with drills for breasts. Gordon twice has to get them to wave away the image.
** Later, we finally get to see the modified Jennifer and she looks no different from regular Jennifer. Laharl, Etna, and especially Flonne are disappointed.
