I loved this if only because of how realistic it was. Yes, it's really short, but it makes sense. It kind of reminds me of "Bambi Meets Godzilla". That made as much sense as this. Vegeta can destroy entire planets. Actually, every single DBZ character can destroy entire planets! Well, the Moon at least.
This really is what would happen. This is why Vegeta wouldn't be in "Super Smash Bros". Well, he's not a video game character so he wouldn't be there anyway. The artwork isn't bad. It's hard for DBZ to have a legitimate crossover with really anything.
