Tartarus.
It has been said to be place in Equestria where evil creatures are held prisoner, and guarded by the mythical three-headed dog, Cerberus. The guardian of this underworld prevents any and all of its inhabitants from escaping into the bright world of Equestria.
However, just as there as many stars in the sky, there are just as many forms of Tartarus and just as many gates. Some of these forms are entirely different worlds, netherworlds spoiled by spite, cruelty, blood soaked taboos, bad one-liners, mimes, and boundless riffraff.
Many a stallion have wondered what lies behind these gates – What worlds are hidden by the darkness guarded by Cerberus? Only the bravest and foolish know, and of those few… Well, they’re more like idiots cause nopony’s ever seen them again once they found that answer.
… What was I talking about again?
Oh, right, the story. So yeah…
As I said, a number of stallions have crossed the gates into Tartarus, but what if a denizen from the Netherworld stumbled into Equestria?
Disgaea Crossover
Official Tumblr: Click here and follow!
i MUST check this out.
I love Disgaea crossovers.
This is a Disgaea crossover, right?
3589321
Great chapter. How long until more Disgaea character's show up?
3589520
Working on it... I don't wanna give too much away who'll appear first...
While I'm at bit disappointed at the interruption of Mao's rampage I think this will do nicely, if anything it will make the time he does go back to full strength all the more sweeter. Also I feel Shining armor should beware...since he always looked like a salt and pepper kind of guy!

Oh, you have no idea the insanity Mao's got planned...
Good chapter.
Good chapter.
Hehehe, that DBZ Abridged reference
So basically Nicholas the Renegade?

Nice to see someone make a crossfic of Disgaea 3 that's slightly based off of that small tumblr page; now to favorite this and see where it goes.
I hope for some possible appearances from a chef who's passion for cooking is as fiery as a good stove
...Boom! 
It's so fun to read Mao's lines in Vic Mignogna's voice, especially when he's pissed off or in a state of insane euphoria
Too bad it wasn't Kotter Sensei that got owned.
Almost thought the mystery pony was Vergil from DMC for a second
Poor Mao being easily outclassed by the Crusaders in his Slaystation 
And he shall be named Caboose
The funny thing is, I'm playing Disgaea 3 right now with some newly-added DLC. It was awesome that Pinkie is capable of being a magichange weapon
3650114 I know, right?
Only Pinkie could have the ability to magichange until the later chapters prove otherwise.
3650337 Something tells me that Twilight's gonna be a bow and Applejack's gonna be a hammer
3650346 True enough. In hindsight, Fluttershy makes a better bow whilst Rarity a sword; a rapier or epee to be precise
Rainbow could be a regular or broadsword
3650361 I recently downloaded him, Revya, and a dragon
He's really cool
You should've seen him in his game, Soul Nomad wasn't bad and even had a few other shoutouts - Heck, we learned what happened to Walnut from Phantom Brave.
As for the Magi-Changes that could be possible... Stop mind taking! Its freaking me out! lol
Great chapter.

I AM SHADO~! THE BRAIN THIEF~!
I have not play disgea 3. But god damn if this hasn't convinced me to. I mean really Mao seems AWESOME
3653946
Evil Geniuses tend to be - He's just as awesome in the Manga.
Yeah like for instance Stein from soul eater and Paradox from Ben Ten alien force, they are crazy and ABSOLUTELY WONDERFUL!
Stein
Paradox
(P.S. I messed up the links the first time around so I deleted my comment :P)
This... this... is really good. Mao is really in character.
Now all we need is a certain honor student to show up...
3729973
Don't you mean... Deliquent? Or, graduate?
3730216
Yup, I meant deliquent. Think my mind jumped somewhere else...
and then mao built a nuke, the end
That Animaniacs reference
I also loved how Mao explained his pocket dimension technology by referencing the Doctor
3738463
Another subtle reference to the animaniacs is that the Prinnies are named after the voice actors for Yakko, Wakko and Dot.
3738504 Now I notice it in hindsight
And this ride just gets more fun. Wonder what weapon twilight would become, since it doesn't seem to sticking to the normal weapon set... unless the cannon was a gun type...
mao is kamen rider decade
Wow Guitar Bro has had a lot of failed jobs, I feel as if Mao had something to do with it
. Also what is Pandora Ignition? 
3744084
It's actually the name of an attack that's used by a certain character...
Well this should be interesting...
The chapter title is definitely a reference
That and the club dedicated to Luna 
3738463>>3738504>>3738545 Which reminds me time for an blooper for this!

this fic keeps getting better
HELL YEA. Updates jus what I needed to start my day the right way
That Double Rainboom reference.
Though I must say: Please~! Axel is not fabulous enough! Now,
VyersMid-Boss! There's a fabulous and handsome devil!3906182
Well, they do have the same voice actor in the games for the English versions... So, maybe some of that charm rubbed off.
3908658 Blasphemy! Voice alone is one thing, but he has to LOOK the part, too.
Great chapter.
Hehehe. I never really got Axel as a DLC character, let alone know much about him, but he seems pretty funny if he got on Mao's bad side way back when.
Meanwhile, I'm surprised the Prinnies had a hidden agenda of their own.
...Took them long enough
Yay! It's bacK!
Keep it up, I'm loving it, and the Disgaea fandom never gets enough love.
