I don't know if setting the Dragonball universe in the Bleedman universe would make sense. Especially with how Dragonball has it's own set geography and events that would just hurt people's heads. Better scenario was if they were simply crossed over. But it is your story and if you think that works and that you might have made it work, I don't know, the stories more important than worrying over about admittingly silly things.
So yeah, shorts not too bad and this is okay. Problem is that you don't take your time with it. You have two scenes that could've been flavoured and had fun with a bit more. I strongly disagree with Birdofterror, adding more background would've wasted time on advancing the story, I say that because if you wanted to add in background, you would've, the fact you didn't wasn't important in the story and getting you to add some detail in probably would've made you feel forced, we would've noticed, hurt the story and yeah. What I recommend maybe is add in some more action to make the scene more active and make our characters more expressive. For example, when Ace asked what do you want, was he just standing unamused or was he hunched over ready. You don't have to as that might end up forcing you as well and isn't all that necessary. But fact is that you were rushed here I think and you had no true fun here, when you don't have fun, we the reader pick up on that and we don't have fun either, take your time, don't rush yourself.
What you achieve though is okay, we've established we have this descendant of Vegeta has a relationship for Mandy, but what kind? That makes it interesting. I'm thinking she was the one that sent Kai, so Mandy has either manipulated or is in works for him, either way it's a cool thing as I can imagine Mandy getting someone like the descendant of saiyans working for her and using him for such things. But again the question is the relationship and I'm not bothered if it's ah, you know, that deep a relationship, because as shown in Grim Tales, Mandy's up for that sort of relationship if it gets her what she wants.
Focusing anyways, so besides what's drawn me is Mandy with an apparent henchmen (Well, however Kai views their relationship, I'm pretty certain Mandy would just view him as a henchman), there are some things in here I have to nit pick about the writing.
This one hurt my head
Ace fall the last few feet from the ground.
I think you mean to the ground, unless Kai was levitating him from the ground.
Another thing that irritated me was the lack of paragraphs, when someone begins a speech or someone else speeches, you start a new paragraph. This made it hard for someone like me to realize a new person was talking until I read the speech tag. Also to note that if there's only two characters talking, you don't need that many speech tags anyways as we're pretty aware of whose talking.
Hope that helps anyways and I will be wanting answers to Kai and Mandy's relationship (Don't spoil it, I'm an anti-spoiler freak, you spoil it, I will paint all your dresses green).
P.S. Nice additions with Tom and Ace as well.
