Gender (jen-der) 
- informal the state of being male, female, or neuter.
Avatars are human by default and only male and female is available upon registration. They are based on the Japanese caricature style of Chibi / Super deform. The male avatar appears more bulky and muscular while the female is more slim and curvy. The notable characteristics on the male avatar are the clinched fist and a foot that points facing the viewer, while the female avatar has relaxed hands with visible fingers and both feet facing at an angle.
Everything on the avatar can be customized according to the user of it. This includes hair, eyes, skin tone, and apparel.
Before the following update a User was given the option of changing their gender by Account Settings, the first 2 changes were free while 10,000 gold was compounded for every extra change, these rising prices were an attempt to discourage 'spur-of-the-moment' gender changes as they were taxing on the site's servers. At one point a User could also change the gender by deleting the avatar and re-creating it, this option was stopped within 2009. Though it must be noted that any special skins or hair that was on the avatar would be lost due to the deletion, but they can be regained by going back to the shops that held the skin and hair the avatar originally had. This is noted due to many hairstyles still being exclusive to one gender.
On July 8, 2010 a new potion (Gender Bender Potion) arrived in Skin Tyte that would allow the user to change genders with a cost of 50,000 Gold. The long request of a fixed price was granted, as the cost of the potion stays at 50K regardless of how many times it is purchased. Therefore making it an effective Gold Sink with more Gaians willing to pay rather then being discouraged by the rising increment of the old system.
Though with the arrival of the new style of changing ones gender, the old method (link to the gender change from profile settings) would be removed. However the Developers made an alternative that if a Gaian had never changed their gender in the past they'd be eligible for two free Gender Bender potions, if they changed gender once, they would be able to get one free potion. The free potions are soulbound, so they can't be available for shop sellback, trade and marketplace sales. Also the potion renders a user back to the default human avatar, meaning that someone who was a different species would have to re-buy the potion that changed them in the first place.
- With the old system if a users wanted to be both genders they could create a mule account, or would quest for gold in order to pay the fee to change their gender switch.
- With the release of the Achievements feature, there is a badge to earn by changing ones gender.
