* CompleteMonster: [[BigBad Fuhito]] is a scientist for the original AVALANCHE. His mindset can be described in a single expression: [[spoiler: Hojo's his hero.]] In addition to that, [[spoiler: Hojo likes him a lot enough to seriously consider leaving Shinra to work with the guy.]] Fuhito found a way to copy part of Shinra's SOLDIER program. With the data he [[spoiler: invents his own variant complete with monstrous degradation of the mind and turning the subject into monsters. He takes two of the [=SOLDIERs=] Zack later remembers and turns them into abominations on par with Hojo's aberrations.]] He later [[spoiler: finds an ancient '''Ultimate Summon''' that has been broken long, long ago. He implants a piece in an innocent girl, transforming her into a weapon to be AVALANCHE's spearhead against Shinra, while the piece starts sucking out her life to rebuild itself. He establishes a firm powerbase to release the Summon, which is to burn the entirety of the world. In the end, he winds up taking it all and merging with it. [[CaptainObvious We all know what happens when you do that.]] ]]
* HilariousInHindsight: When Cait Sith is introduced he's easily damaged and is nearly useless in a fight. Reeve is frustrated but later has an idea to improve Cait Sith's fighting capabilities. Consider how useful he was in ''VideoGame/FinalFantasyVII'' - that was ''after'' Reeve upgraded him!
* MagnificentBastard: [[spoiler:Rufus.]] He's the one controlling AVALANCHE for most of the game in order to [[spoiler:discredit his father and make Shinra look bad, and many of AVALANCHE's attacks, such as sabotaging the rocket into space, are done to further that goal.]] Why? So he can take over Shinra. And he's a KarmaHoudini to boot, [[spoiler:since the President can't admit that the Vice-President and his own son was scheming with his enemies right under his nose.]]
