YMMV: Makai Kingdom
- Anti-Climax Boss: The optional encounter with Asagi must be unlocked with a level 1000 character and a massive amount of mana. Asagi herself is level 50 and will likely go down with one hit.
- Awesome Ego: Zetta is arrogant, hammy, and boastful, which is the reason for a lot his fans.
- Big Lipped Alligator Moment: That "picture" when King Drake powers up.
- Funny Moments - Upon recruiting King Drake, you'll see his Intelligence Aptitude is only TEN PERCENT.
- Game Breaker: Zetta.
- Ho Yay: Quite a bit coming from Alex, but King Drake & Zetta offer up this exchange:
Zetta: Aren't you the one who attacked me in my sleep?KING Drake THE THIRD: Only because I wanted your junk.Zetta: ... You sick bastard. I didn't know you swung that way.
- Marth Debuted in Smash Bros.: Remember Petta, the Badass Freakin' Overlord's daughter? She was part of the content of Updated Re-release that is exclusive to Japan. Despite this, She appears in both Disgaea 4: A Promise Unforgotten and Disgaea D2 A Brighter Darkness; games that made it to the west.
- Moral Event Horizon: Seedle crosses it three times. He tried to flirt with Salome in life. She didn't reciprocate, so he tried to rape her, only to get a knife to the gut for his troubles. Now fast forward to the near-end of Episode 9. He continuously says that everything would be better if he had done so, and he wants to kill her off again out of pettiness. Alexander foils the attempt. Then, when Salome is about to be resurrected by Pram and Zetta, Seedle intervenes AGAIN by attacking Pram to disrupt the ceremony and then breaks Zetta by talking about how he got all his power from Salome. Alexander finally has enough and presumably dispatches Seedle off-screen.
- In Japanese, Zetta's self-declared title is Saikyou no Maou, the strongest Demon King. Although variations of the original title exist (Strongest Overlord in the Cosmos), he commonly refers to himself as one Badass (Freakin') Overlord. Guess which one fans preferred?
- The title of the game itself was originally called Phantom Kingdom in Japan. It was supposedly renamed in order to remove any confusion about it being related to the previous game, Phantom Brave. Since the general atmosphere is much closer to Disgaea than Phantom Brave, this makes a lot of sense.
