1. Sephiroth was supposed killed by Cloud in Nibelheim reactor but the crystalized mako kept his body alive but crippled but his will was still alive the JENOVA inside him took over and made cloud hand over the black materia which summoned meteor which nearly destroyed the planet but thanks to lifestream and holy it was stopped but afterwards Cloud knew sephiroth was still alive he left his body for a while travelled the lifestream and killed sephiroth for good.

Cloud was never in SOLDIER after his friend Zack was killed he made up lies and stoies saying he was in soldier. Red XIII came from the tribe of cosmo canyon but they where all killed he thought his father was a coward but Bugenhagan showed him the true hero his father was. Cloud also didnt know much on Shinra.


the Lifestream/Mako/Materia was Original and believable the story of 6 was so unrealistic. with 7 the thing is that the story is so long and has different parts which give you time to understand the rest. Sephiroth's clone killed Aeris because she was the last of the ancients and the last with the power to stop him from acquiring the black materia to summon meteor to make a wound so big in the planet lifestream will come gushing out and heal the wound but sephiroth will be at the centre of this wound gaining power and the title of a god.

with Jenova she killed off almost all the ancients and had the power to destroy the earth therefore Weapons where created these where Diamond, Sapphire, Ultimate, Ruby and Emerald these where made to defend the planet when it was in danger but since the ancients managed to suspend Jenova the weapons where put into slumber untill they where needed again and after the black materia was given to sephiroth they awakened.


most of those things there pose no similarities to 6. 6 was messed up in a few ways but 7 adapted a few of them messed up things to make the story of 7 better which was slightly more believable.

Cid was also an engineer fo shinra at one time so he built other things like tiny bronco he could also pilot other things greatly eg train and boat and planes
