When one of my friends got a demo for Final Fantasy VIII, I was pretty excited to check it out. It seemed like a pretty cool game at the time. The summon for Leviathan was ridiculous, but it looked really nice. Ever since then, my mental picture for Leviathan looked like this:
Curiously enough, two shows for the Spring 2013 Anime Season have characters named Leviathan: Zettai Bouei Leviathan and Namiuchigiwa no Muromi-san.
They’ve mostly kept the blue motif, but my image of Leviathan is shattered forever.
