Thousands of years ago (at about the same time Hanasia novel was last updated), a gang of absolutely generic villains called Bojack gang would go around the universe, spreading horror with their genericness.

At some point, the Kais decided that this should stop, so they sealed them into King Kai's planet, which King Kai conveniently never mentioned, not even after his planet was destroyed, which would make you think the first thing he would do was to warn Z fighters about the imminent danger.

Also, if Kais interfrering with the matters of mortals is against the rules, why did they decide to seal Bojack's gang in the first place? And why didn't they do the same thing to other villains, such as Freeza? Darn, this makes so little sense that it hurts! Well, welcome to a Dragon Ball movie, honeys!

Bojack is giving Gohan a lovely, affectionate hug. A bear hug, that is! Breaking his bones in the proccess!

'Har har, you'll die,' Bojack laughs, enjoying the kid's screams of pain.

Suddenly, Gohan smiles. 'I was kidding,' he says.

'Huh?'

'This doesn't hurt at all. You're not strong enough to damage me.'

Bojack lets go of him. 'In that case, look at yourself in the mirror,' he says and produces a handheld mirror out of nowhere.

Gohan looks at his reflection. 'GOSH, I'm so ugly. I look like a retarded meth addict. Who drew this special?'

Unable to take his ugliness, Gohan vomits blood and dies.

Seriously, Salagir should pick more carefully those who draw the specials.

The camera back to Bojack, who's now wearing a black, carnival mask, for some reason. Or at least that's what the way he's drawn makes him look like. 'Hey, everybody, look at me. I'm Batman!'

'LIAR,' a scream is heard as Piccolo (also wearing the same mask) charges at him. 'I'm the real Batman.'

Meanwhile, in a Nickelodeon universe...

'I'm the real Batman!' Cat giggles.

'No, Cat, you're not,' Sam sighs.

'Aw,' Cat says, disappointed.

Meanwhile, in another, unidentified, Dragon Ball universe...

'Vegeta!' Nappa cries. 'What does the scouter say about the batmaness level of this special?'

'IT'S OVER 9000!'

With Piccolo's corpse next to him, Bojack is staring at Vegeta, who's preparing his final flash, taking some unneccessary anime poses and producing some unnecessary dramatic cries.

Bido is standing in front of his master. 'Are you sure I can take this, lord Bojack?' he asks, a little uncertain.

'Yeah, dude, no worries, I'm here too,' Bojack comforts him. 'I'm having your back. We'll deflect this blast together.'

Vegeta fires the final blast. The last moment, Bojack gets out of the way. Bido's eyes bulge in terror as he tries to deflect the blast himself. 'But... but you said we'd do it together...' he cries.

'Well, there is a thing called lying, which often makes your life easier,' Bojack calls out as Bido's body is disintegrated.

Next, he procceeds to kill the exhausted Vegeta.

Goku meets his friends in the afterlife, before King Yenma, the gargantuan orge who judges the dead.

'Sorry, dad,' Gohan says, his head lowered in shame. 'This time, Sixteen wasn't there to have his head crushed to a pulp or something for my sake, so that I could release my hidden power.'

'No worries, son,' Goku laughs. 'We'll strike back. I'm pretty sure King Yenma is nice enough of a guy to let us to the living world for one more day.' And, turning to the judge of dead for confirmation, he asks: 'Right, dude?'

A moment of silence.

'Actually, I'm a jerk, so I won't let you go back,' he says casually.

Another moment of silence and gag sweatdrops.

'Oh... so what are we going to do now?' Tenshinhan says.

'Dunno, kiddos, enjoy your afterlife,' King Yenma shrugs. 'Eat cookies, play Mario Kart, have sex...'

Suddenly, a green skinned fighter appears out of nowhere.

'Zup, Goku?' he greets casually.

A moment of silence.

'Umm, do I know you?' Goku scratches his head.

'Of course!' the fighter chuckles. 'I'm Pikuhan.'

'I don't remember you.'

'We fought in the Otherworld tournament final!'

'Still doesn't ring a bell.'

'Oh, come on, just because our meeting was an anime filler which made zero sense and was written by guys who didn't know shit about power levels doesn't mean I don't exist!'

More silence and indifferent looks.

'Maybe he's a Yoshi,' Piccolo says.

'Fuck you,' Pikuhan whispers and disappears.

More silence and sweatdrops.

'Wanna guys go and get some tacos?' Vegeta asks.

Some of the Z fighters answer in unison, saying 'Sure' or 'Great idea' and, the very next moment, everyone disappears, leaving King Yenma alone.

'I hate this job,' the giant moans.
