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.
