Zack and Cloud are retrieved by Shin-Ra forces and kept in custody. They are subjected against their will to biological experimentation involving genetic material from
Jenova, under the supervision of
Professor Hojo. Eventually, Zack breaks out and literally drags Cloud with him during their escape. Zack gives Cloud some of his clothes and gets them transport to
Midgar. During this time, Cloud is weak, groggy and somewhat delirious, as he had reacted more strongly to the experiments than Zack did. However, Zack talks continuously to the unresponsive Cloud about his life and his plans to become a mercenary in Midgar, get rich and be with his girlfriend. When they finally arrive outside of Midgar, the Shin-Ra security force that have been searching for them finally catch up. They try to detain the escaped prisoners, but Zack fights back to defend both Cloud and himself. The Shin-Ra troops, armed with machine guns, shoot Zack to death and leave Cloud for dead after seeing his vegetative state. However, Cloud manages to recover. The combined weight of all this trauma finally makes him snap, and he adopts Zack's persona, combining it with his own. He believes that he was successful in joining SOLDIER, and that he fulfilled Zack's role in the fateful mission to Nibelheim. Cloud takes Zack's buster sword and continues on to Midgar. Upon his arrival, Cloud seeks work as a mercenary, just as Zack said he intended to do. This is where
Final Fantasy VII begins.
