Funny / Dungeon Fighter Online

In-game

• Harlem area:
  • Early in the Harlem scenario quests, the player has to ride a giant worm-like creature to traverse a desert with hunters chasing him. One can actually jump off the worm mid-run and, if done repeatedly, the player's character starts to lampshade the stupidity of this, eventually culminating in self-loathing.
  • At some point, the Adventurer has to participate in some cage fights in the Fight Club dungeon to get the location of the questline's MacGuffin. When asked by the Fight Club owner to write their name down, they claim to not have a name, so the owner just writes a mildly-insulting descriptor in its place, like "Nameless Boy" for the male Mage. By the time they get into the Fight Club proper, the "name" has been twisted into an Embarrassing Nickname (e.g. "The Boy Who's Too Stupid To Remember His Name") and announced to the crowd.
  • The 95 cap trailer "Episode 1: Ricardo" shows what Ricardo the Heartbreaker is up to after the events of the Harlem scenario questline. After narrowly getting away with pilfering Isys-Prey's egg from the Dungeon Fighters, he tries to force it to hatch in an unidentified warehouse. The methods he uses escalate in absurdity (at one point using the Witch's Atomic Collider, of all things), eventually attempting to rig it with explosives, only to find out that even that didn't work (at least, until he walks out of the warehouse). The whole thing is accompanied with goofy music and Ricardo screaming like an idiot the whole time, giving a nice change of pace from the Darker and Edgier tone of the Harlem storyline.
• The juxtaposition of the game's myriad fantasy settings doesn't get any more apparent than the end of Sirocco's quest line, which ends with Sirocco scaling up the Sky Tower and breaking through the pentacle separating Arad and Empyrean... only to be greeted by an army of Empyrean Humongous Mecha and unceremoniously blown to pieces by a Macross Missile Massacre. It's hilariously anti-climactic, especially given the other Apostles' comparatively more glorious ends and the sheer amount of crap Sirocco's dimension-hopping shenanigans caused on DFO's multiverse.
• At the end of the Ozma scenario questline, an animated cutscene shows Nilvas Gracia holding open the currently-closing gate to the Dark Side after Ozma's defeat, allowing the Dungeon Fighters and Lemidia priests to escape with his sister Grandis in tow. The Stinger to this cutscene shows Nilvas's Imposter form disintegrating due to Ozma's defeat, leaving only his horns and some patches of purple skin. Shortly after, Niu (the Battle Mage from the Harlem questline) appears through a rift portal next to Nilvas, apparently having been dimension hopping in search of Pai, her fellow mage. The two stare awkwardly at each other for a few seconds before Niu breaks the silence by asking Nilvas if he's a half-breed, accompanied by a Super-Deformed version of her in a speech bubble. Nilvas (also with an SD speech bubble) replies with a confused "no", since half-breeds don't exist in Arad.

Meta

• The hilariously low-budget Kunoichi trailers, both for the Korean verison and DFO Global.
• The Golden Capsule event trailer is pretty over the top for something as mundane as an EXP capsule that gives a few dozen levels.
• The Korean version's Gunblader/Agent trailer takes place in an intense fencing duel. What does that have to do with the class, you might wonder? Well, one of the fencers eventually takes the easy way out and just caps the other guy. The Stinger has the "Gunblader" get arrested for his efforts.
• DFO Global's official YouTube channel has this video where Danjun tries to play Anton Raid with MJ giving him advice on gimmicks. It ends as well as you would expect from someone who's speculated to be either an artist or musician on Neople as opposed to one of the programmers. The top-notch editing just adds to the humor.
  (the miniboss Danjun is fighting starts winding up for a homing tornado attack, which he's had no success at evading so far)
  MJ: Dodge! Dodge! Dodge! DODGE! DOOOOOOODGE!!!
  Danjun: Okay okay okay AHHHHHH!!
  (Danjun walks in a random direction and avoids it by sheer luck, which is lampshaded by the subtitles)
  (Smash Cut to an Anton plushie in a hammock with the subtitles "Screen adjustment time for peace of mind")
  Danjun: They (party members) are quite angry! Why they are so angry?
  ("Angry" music plays as the video colors invert and the camera is zoomed into MJ's Blank Stare)
  (cue the Anton plushie again, with the subtitle "Screen adjustment time for cleaner chat window")
• The advertisement for the level 100 cap in KDNF features personifications of keyboard keys, as if to self-deprecate about how mechanically difficult the game is. Moments include Q through Y, A through H and the Z, X and C keys all doing squats (with the relatively underused right half of the keyboard cheering them on), the Print Screen key sunbathing, and the Tab key hooked up to medical equipment and flatlining repeatedly in its service to alt-tabbing out of the game to hide it from the player's Education Mama.
• The "42 Days of DFO" event trailer is a parody Work Com revolving around a Knight and a female Gunner (read: Twitch moderators Duni and Tigger cosplaying them) who live through their Neo: Awakening updates and all the ups and downs a typical endgame DFO player experiences, such as botched raids, excitement over Mythics, losing weapons to reinforcement, and the "Fire-Forged Friendship" the two characters go through over the course of the month.
• For the Demonic Lancer's Neo: Awakening, Neople released a fake commercial advertising Neo: Awakening as some sort of drug, and the Demonic Lancer is portrayed as the comically despondent person that might need such a thing. The commercial even has a disclaimer saying that "Using Neo: Awakening will not automatically make you the best DPS in raids" and side effects like "getting addicted to DFO".
