Half steve, half zombie skin. Everybody will be afraid of you.
Steve is the character that can be controlled in Minecraft. The two default player skins are known as Steve, a name suggested by Notch as a joke and confirmed on the ‘Profile’ page near the section that allows you to change your skins, and Alex, with all unchanged skins being split between the two default skins. In the End Poem, after beating Minecraft you are called a player.
Zombies are common, undead hostile mobs.
