Skyrocket likes to describe himself as a "moneymaker"... he'll do whatever it takes to turn a profit from whatever his expense has to make- regardless of loss of life or... others' property.
What does he do with the money? Nothing useful. 
He's rather anomalous, himself. He seems to carry wealth, yet nobody knows where the money goes. Those who interact with him believe that with every scale spent, that portion of the economy is replaced with something utterly useless.
