Why does Zorro like to draw a Z on the enemy?
Z is the symbol of ZORRO, because Zorro's English name is Zorro with a "Z" at the beginning. Zorro painted the word Z on the enemy to make him remember this moment. Because he did bad things, he painted the word Z to remind him that he can't do bad things again, otherwise Zorro will punish him and let him know that doing bad things will not have a good result.
