When you create your avatar you can choose between having a female or a male avatar. It is not possible to change the gender of an avatar once it has been created.
Please seek out a beauty specialist skilled in plastic surgery, hair dressing or body sculpting as they will be able to help you with your request.
Unless the name violates the EULA or ToU or you happened to write your real name as your avatar name, we do not change the name of your avatar. The reason for not allowing a change of your avatar name is that you build reputation and trust inside the Entropia Universe by the name of your avatar. To allow this to be changed would undermine confidence in existing avatar relations.
