Inside the Sector 5 Reactor.

The Sector 5 Reactor (伍番魔晄炉, Goban Makō-ro?) is one of the eight Mako Reactors built by the Shinra Electric Power Company to power the metropolis of Midgar in Final Fantasy VII. In the original Final Fantasy VII its layout is exactly the same as the Sector 1 Reactor's.


Spoiler warning: Plot and/or ending details follow. (Skip section)

Crisis Core -Final Fantasy VII-Edit

Zack Fair and his fellow SOLDIER First Class, Sephiroth, enter the reactor in search of the rogues, Genesis Rhapsodos and Dr Hollander. They fight Sahagin-like monsters, but with a strange mutation - they have the face of their missing friend, Angeal Hewley.

Further investigation discovers both Angeal and Genesis were parts of Project G, an experiment performed by Hollander to make a modern Ancient. The experiment was a failure and Genesis had begun to slowly degrade, and could make copies of himself on humans.

Hollander and Genesis arrive, and while Sephiroth deals with his old friend, Zack chases after Hollander until they reach the bottom of the plate. When Zack has Hollander cornered, Angeal arrives and shows Zack he is a monster by sprouting a white wing, then attacks. Zack refuses to fight his old friend, but the ground beneath Zack breaks from Angeal's attack, and Zack falls into the slums below.

Final Fantasy VIIEdit

Sector 5 Reactor.

Following their successful attack on the Sector 1 Reactor, the members of the eco-terrorist organization AVALANCHE hope to repeat their victory on the No. 5 Reactor. After climbing through the city's underground subway system they break into the reactor. AVALANCHE fights its way down to the main generator and plant the explosives. On their way out, President Shinra greets the insurgents; Shinra had known of the attack beforehand, and prepared the reactor as a trap for AVALANCHE.

The robot Air Buster is sent in to defeat the terrorists, while President Shinra leaves, certain of victory. The party destroy the Air Buster and as it explodes, Cloud Strife is caught in the blast and falls into the slums below like Zack had done seven years earlier.

Although the reactor explodes, it is later seen in use powering the Sister Ray cannon, indicating Shinra repaired the damage, unlike the Sector 1 Reactor, which was utterly destroyed and never repaired. This is odd, given that Jessie said she would make her next bomb even more powerful than the one that destroyed the Sector 1 Reactor, but is supported by the visibly smaller explosion that results. Given that Shinra had enough foreknowledge to set an ambush, it's possible the explosion was mitigated by them in some way.

  • At the core of the reactor where the bomb is planted, the structure reads "1997", the release date of Final Fantasy VII, and the Greek, "σμκινσ", which roughly translates to "smkin", the name given to the rooms of the Sector 5 Reactor in the data. Interestingly, the Sector 1 Reactor reads "1998", and while there is text next to it it is indecipherable.
