* Vyers AKA Mid-Boss. He tries to be charming, but no one takes him seriously except Flonne. Of course, she also calls him Mr. Mid-Boss.
** Episode 7 has him meeting Maharl, who is supposedly King Krichevskoy's "second" child. Double funny when it's later revealed Vyers [[spoiler: is Krichevskoy reincarnated]].
--> '''Maharl''': (''after Vyers has a FreakOut'') Is this man always this strange?
--> '''Laharl''': Yeah, don't talk to him. It might be contagious.
* The Prinnies, Doode.
** The Prinnies get an entire episode dedicated to them, in episode 8 they attempt a rebellion. But it ends in failure, as one would expect from a plan conceived by a Prinny.
* From episode 1, Gordon, Jennifer, and Thursday's first appearance involves them crashlanding on top of some demons who'd been trying to kill Laharl.
** Not long after Laharl meets [[InnocentFanserviceGirl Jennifer]], and wants no part in any MarshmallowHell.
--> '''Laharl''': Keep that voluptuous body away from me!
--> '''Jennifer''': Huh?
--> '''Flonne''': Laharal, what's the matter?
--> '''Jennifer''': Oh, I know. (''with a smile'') You're going through puberty, aren't you? My body is much more mature than your girlfriends', so it's no wonder.
* Episode 3, the magic stone which causes a kind of FreakyFridayFlip. Switching Flonne and Etna's personalities, as well as their outfits. Upon awakening the next morning, Etna acts kind and caring, while Flonne becomes selfish and cruel.
--> '''Etna''': Good morning, everyone.
--> '''Flonne''': Yo Highness!
** The Prinnies overreaction to Etna's sudden acts of kindness.
--> '''Prinny''': (''crying TearsOfJoy'') We're so happy Doode. Lady Etna's being nice to us!
* Episode 12, Seraph Lamington's choice of punishment for Vulcanus. Transformed into a frog. The situation becomes far less funny when it's time for [[spoiler: Flonne's]] [[TearJerker punishment]].
--> '''Seraph Lamington''': This is the punishment I have meted out to Vulcanus. In that form he must learn humility and discipline for the next thousand years.
--> '''Etna''': (''clapping'') That's completely awesome!
