Planet Earth. It's been 20 years since Goku defeated Buu.
20 years worth of off screen time! Wow!
Right now, Trunks is sitting at his room and moaning to
one of his servants:
'But why did he call me a lucky bastard?' he wonders in
a sad tone of voice. 'Just because someone is born
filthily rich, with all his practical problems solved, with
super powers he never had to work for and all girls fall
for him, that automatically makes him a lucky bastard?'
'Pretty much, sir,' the old servant, dressed in a proper
uniform, answers stoically.
That moment, Trunks receives a telepathic message from
Dende, the god of Earth: 'Trunks, come to the lookout
immediately. I'm sending the same message to all the
strongest fighters on Earth.'
'Couldn't you just text us or something?' Trunks wonders.
'There is no internet connection at the lookout, Trunks.
We've been through this,' Dende sighs. 'Now hurry up
and come. Something totally unexpected happened. I still
can't believe it. I mean, it's totally unbelievable!'
Trunks widens his eyes and tries a guess: 'Ciara Bravo's
body finally hit puberty?'
'Well, not THAT unbelievable!' Dende answers. 'But still,
you have to come quickly.'
At the lookout, Dende, Popo and Piccolo are waiting for
the Z fighters to come while chatting with Vargas, the
visitors from another universe.
'I'm surprised, though,' one of the short, bird formed aliens
comments. 'In all universes we've visited so far, we've
never seen a planet where people are cool with a dog
being their king.'
'Well, their options in the last elections were either him
or Trump, so... you know... the dog, hands down,' Piccolo
explains.
The Z fighters arrive: Goku, Vegeta, Gohan, Goten, Trunks,
Pan, Bra and Videl.
The leader of the Vargas mission starts explaining: 'Greetings,
honorable warriors. We are the inventors of interuniversal
travel. We made that discovery totally accidentally.'
'Yes, totally accidentally,' Popo, who secretly controls the
fates of all creatures in the omniverse thinks and laughs
evilly in his head.
Goku scratches his head. Gohan corrects his glasses, with
an expression that shows he understands.
'You see, gentlemen,' the Varga continues, 'all universes
started with the same possibilities, but, somewhere in the
proccess, diverged because of different choices made by
individuals or other random factors.'
'Wow,' Gohan whispers.
'What?' Goku asks.
'We decided to select a few universes and organize a
tournament among them,' another Varga carries on.
'So far, in our attempt to find really interesting universes,
we have visited hundreds.'
'In how many of them did Spongebob remain a good
show past Season 3?' Goten asks.
'Err... none...' a Varga laughs awkwardly.
'So, do you want to come?' the leader Varga asks, arms
behind back.
'Wow, a whole world of parallel timelines,' Gohan says
in enthusiasm. 'I'll definitely come, albeit as a spectator.
For a scientist like me, studying such a fascinating thing
is a dream come true. Right, dad?'
'What?' Goku, who hasn't understood anything of what
the Vargas said, scratches his head.
The Vargas facepalm. 'Okay, I'll explain the multiverse
theory one more time,' one of them sighs.
'Don't bother,' Piccolo interrupts him. 'I'll do it. I speak
his language.'
'You speak his language?' the aforementioned Varga
raises an eyebrow.
Piccolo stares at Goku and starts drawling in a somewhat
loud voice, as if he's talking to a retarded child: 'Goku...
good fooood... strooong guys to fiiiiight... wanna... cooome?'
'Yaay,' Goku raises his arms in the air.
'I'll come too,' Vegeta says casually, arms crossed. 'Something
seems fishy to me, but there is no way I'll let Kakarrot
go to a tournament without me.'
'Oh, come on, don't be suspicious, sir,' one of the Nameks
that accompanied the Vargas says. 'It will be just a pleasant
tournament. Nothing bad has to happen.'
'Yes. Nothing bad has to happen,' Mister Popo says in his
head. As soon as the ship has vanished with the passengers,
he starts laughing evilly.
'Err... is something wrong, Mister Popo?' Dende asks.
'No, I just remembered a joke,' the nigga supposed servant
answers and procceeds to tell it: 'How many of Lincoln Loud's
sisters does it take to create a good show?'
'Err... how many?' the supposed god laughs in embarassment.
'All of them but Lily,' Popo declares.
