Cloud is a clone of the guy with the black hair next to Aeris at the end. I play FF7 and have a guide book. And does it really matter what his name is. Also I can look like him with a hair bleaching and a big sword.
Sorry to beat a dead horse, but…
Cloud was born in the sleepy mountain village of Nibelheim, along with Tifa Lockhart. He grew up isolated from the rest of the village children, feeling himself somehow better than them, though it is implied that he longed for the friendship of the others. However, when Tifa and the others attempted to climb Mt. Nibel, Cloud followed them, Tifa fell from a bridge and her father blamed Cloud. He resolved to join Shin-Ra's elite SOLDIER force, hoping to prove to others (and most of all to himself) that he could be as strong as the legendary Sephiroth. At this point he made a promise to Tifa, vowing that he'd protect her when she's in need.
However, he was unable to make it into SOLDIER and became an ordinary Shin-Ra guard. In this role he was to return to Nibelheim, along with first-class SOLDIERs Sephiroth and Zack Fair. Ashamed of his failure, he kept his identity from the townspeople. They were to investigate a problem at the Mako Reactor on Mt. Nibel, and Tifa was to act as their guide. When they reached the reactor, Sephiroth discovered Hojo's failed experiments with mako soldiers and his own mother, Jenova.
Early in the game, however, Cloud's past is a mystery. He claims that he was in the city of Nibelheim with Sephiroth when Sephiroth discovered his true origins as a Shin-Ra experiment, subsequently went berserk, and massacred the local population. After finding Tifa wounded, Cloud confronts Sephiroth. Yet, when examined closely, Cloud's memories of these events and others are filled with holes that prevent them from making sense. It all comes together later in the game.
As it turns out, Cloud suffers from a mixture of amnesia and mind control. Although he had been in Nibelheim during Sephiroth's rampage, he was not there as a top ranking member of SOLDIER, but a grunt under the command of both Sephiroth and another man named Zack. Following the incident, Cloud and Zack were captured by Shin-Ra and experimented on with Jenova cells for several years. Upon their escape, Zack was killed, and Cloud was left for dead in a confused stupor, believing himself to have been the SOLDIER Zack was.
Yeah, you're wrong.
And yeah, I'm a FFVII fanboy…
I'm so ashamed… :[
