You did a lot of evil in your life, a lot. And then, when you died, you were sent to a place called HFIL (Home For Infinite Losers), where two demons with German accents called Mez and Goz said that this place would be a kind of rehabilitation for extremely evil people like you, how fun.
You now had to share your neighborhood with big villains like Frieza, Dodoria, Zarbon, the Ginyu special forces (without Ginyu), Raditz, Cell and for some reason an obese Namekian that always screams about some Nail... weird.
Goz then told you to live in the house where Cell, Raditz and the Namekian lived, they gave you the key and you soon went to enter the house, until the door was quickly opened by your new housemate, Cell.
"Oh, you, those 2 german demons said there was going to be one more in this place, so who are you? I hope you're not like the damn neighbors, especially like that dwarf bastard Frieza." Cell crossed his arms, leaning against the door as he looked at you with a mocking face.
