Lego customs are lego figures made with custom or in-set lego pieces. They can have custom guns, custom heads, horns, and a bunch of arms. I have made some custom faces for my minifigs with mom's sticker machine. I have made an angry zombie face, normal zombie face, and man with a mustache face. They turned out awesomely! I hope I can do more soon. I own one custom weapon and a clone trooper rifle. I have only one custom figure I have bought -- it is a zombie with a chainsaw arm it is very good.
