This story happened in Universe 17.
As Cell Games approach an end, the two greatest powers in Universe 17, Gohan and Cell, are having a beam clash, the former firing one handed because of his injury. Cell is obviously superior and is going to win.
Z fighters are watching, helpless. 'It seems Kakkarot's brat is done for,' Vegeta thinks. 'Perhaps I should go and help him somewhow. Such as, dunno, by going behind Cell and distracting him with a blast or something.'
A few seconds pass, Vegeta staring indifferently, blinking from time to time. 'I mean, seriously,' he resumes in his head. 'Any effort of mine would be preferable to just standing here and staring like an idiot, which is exactly what I'm doing right now.'
More seconds pass, Vegeta just standing there and watching, blinking from time to time.
Meanwhile, Cell is almost there. 'HAR HAR, thanks for all the good moments. Goodbye!' He cries triumphantly.
'Uungh, I can't go on anymore,' Gohan struggles, clenching teeth.
'Hang in there, son,' Goku (currently in the afterlife) encourages Gohan. 'You haven't used all your power yet. Get angry and release your hidden power.'
'Dad, I already did that in order to transform into Super Saiyan 2,' Gohan reminds him.
'Oh,' Goku says sadly. And, one second later, he cries cheerfully: 'Then use your enraged power on top of your Super Saiyan 2 power.'
'Dad, I already did that to produce that blast in the first place despite my injuries,' Gohan reminds him.
'Oh,' Goku says sadly. And, one second later, he cries cheerfully: 'Then use your enraged power on top of your enraged power on top of your Super Saiyan 2 power!'
'Dad, drop it!' Gohan sighs. 'I just don't have any more hidden power. Okay? Deal with it.'
'NO, SON, you have to do something!' Goku cries.
However, Gohan resigns to his fate and gets engulfed by Cell's blast.
After a few moments of mourning for the poor child, the Z fighters decide to make a last stand.
'Come on, bitches,' Cell provokes them. 'To show you how tough I am, I'll take all your blasts at once.'
Each Z fighter prepares his most powerful blast, then they all fire simultaneously.
'FINAL FLASH!' Vegeta cries.
'TRI BEAM!' Tenshinhan cries.
'KAMEHAMEHA!' Krillin cries.
'KAMEHAMEHA!' Yamcha cries.
'NAMELESS BLAST WHICH NEVER WORKS BUT I USE ANYWAY BECAUSE IT LOOKS SO COOL!' Piccolo cries, firing the same blast he used againt Cell's 1st form.
All blasts unite and produce a deafening explosion.
As the Z fighters wait for the smoke to dissipate, so that they can see the aftermath, they hear a voice behind: 'Err hem, here I am, gentlemen. I dodged!'
Everybody turns around and sees Cell.
'Wait a minute, didn't you provoke us to fire our ultimate blasts in order to show how tough you are?' Vegeta asks.
'Yes,' Cell nods. 'And I dodged them.'
'But doesn't dodging them instead of taking them defeat the purpose of showing how tough you are?' Vegeta asks.
A moment of awkward silence. Cell sweatdrops.
'Just die,' he says really fast and kills everybody but Krillin within the next two seconds. Then he drags the dwarf to outer space.
'YOU MOTHERFUCKER!' Krillin yells. 'You killed all my friends. I'll avenge them. I'll cut you into pieces with a kienzan. I'll...'
'We're in outer space,' Cell reminds him. 'Aren't you supposed to vomit blood and die under those conditions?'
'Oh, yeah, that's right. I'm sorry,' Krillin chuckles awkwardly.
The very next moment, he takes a horrified expression and dies, vomitting blood.
And so, Cell lived happily ever after and had a lot of beautiful children.
