Here are the characters available. You can have anywhere between 1-3 characters that will be randomly selected for you. If you are not satisfied with your first randomly selected characters, then you can request another random selection, and then a third if you are not satisfied with the second. However, whatever your third selection is, you must settle with that. The reason for this is to avoid everyone from selecting the same characters. Some will be more powerful than others from the beginning due to certain inarguable advantages one race has over another. (Ex: Most of Frieza's goons were normally stronger than the typical Saiyan; Pretty much every being not of Earth will likely be stronger than an Earthling.) But, as powerful as some will start out, their high starting PL will be countered by having a difficult time building their PL with training while those who start out with a weak PL will have an easier time building their PL.
