Future Android 18 Character Facts

Future Android 18 is the alternate timeline counterpart of Android 18 seen in the special Dragon Ball Z: The History of Trunks, and in the episodes "Ghosts from Tomorrow" and "Free the Future" of Dragon Ball Z. This version of Android 18 is more cruel than the one seen in the main timeline, and is bent on doing nothing more but destroying and killing. 
Similar to her main timeline self, Android 18's petite form and beautiful face hides her massive strength. She has shoulder- length blonde hair (which, according to her, is artificial and cannot grow back), blue eyes, and hoop earrings in both ears. She keeps the left side of her hair behind her ear. When she is first activated by Gero, and throughout her entire life, she wears a blue denim vest and skirt (with the Red Ribbon logo on the back of the jacket) with dark blue stockings, brown boots, and a black undershirt that has white and black striped sleeves. 
In contrast to her main timeline self, Future Android 18, alongside her brother, was extremely sociopathic and cruel, taking joy in killing and destruction. According to 18 and 17, their personalities were the direct result of Dr. Gero's attempts at programming them to hate humans as part of his bid to conquer the world. Despite her brutal and cruel nature, she has shown instances of self restraint, such as scolding her brother for murdering a clothing store salesperson despite intending to let him live.
