Alex is the one of the default characters in Minecraft. Her age is unknown, but since she was released in 2014, September 2nd, she has existed for 5 years.
Alex has long bright orange hair hanging to the left side, pale white skin, and green eyes, with a light-green shirt (un-tucked on the right side, and a dark green belt wrapped around it), a pair of brown pants, and grayish boots. Alex appears to have pinkish lips, and has thinner arms than Steve.
1.8, the first release of the 'Bountiful Update', added and changed many aspects of Minecraft. Among many things, the update made it easier for map makers to create adventure maps, as it added many blocks, mobs and a structure for Survival play, and many commands were added or extended. The world boundary was enforced dynamically, many Survival mechanics were changed, and Spectator mode was added. Performance was increased significantly, and many options for world customization were added. A new default skin was created by Notch for female players, as Steve was the first default skin and looked more like he was made for male players, the female skin was named "Alex" and was taught the rules of Minecraft, and became Steve's comrade.
Alex is more sweeter than Steve, being more of an animal breeder, she also tries to reason with Herobrine when he attacks that she can live. Alex also presents herself as a sophisticated and comedic individual who looks to lighten up a problem, using whatever means she can to cheer someone up or just be helpful in general.
