Power

The power level in the BCU is different from Dragon Ball. A power level of one means that character can take on one person with a fair chance of winning. A power level of two means that character can take on TWO people with a fair chance of winning. A power level of zero however, means that there is a very low chance of winning by themselves. If a character has a power level in the negatives, like -1, that means two of that character would have a low chance at winning. So for example, let's say someone with a power of 100 is taking on someone with a power of 50. The character with a power of 50 would have a really low chance of winning, but if there were two of the same character, then the power would double to 100, and it would be just about an equal fight.
