For me, the KH Sephiroth fight. My jaw dropped the second I saw him drop down and I went into full panic mode.
Also, The emerald machine or whatever it is called in FFVII. It scared the fuck out of me since I have a fear of deep sea monsters/creatures.
Lastly, the dinosaur in the first desert area of FFXII. It was ridiculous to see that thing walking around when I was level 1 or 2 after fighting off rats.
