In the very first Final Fantasy, Warmech was an enemy that could be randomly encountered on the long sky bridge preceding the fourth elemental fiend, Tiamat. Warmech was the strongest non-boss in the game, as it had a nuclear blast attack that attacked your entire party for a tremendous amount of damage, as well as health regeneration, lots of armor and strong physical damage output.
Subsequently, it rewarded you as if it were one of the elemental fiends if you defeat it, but the existence of Warmech was one-part easter egg, being a high-tech opponent in a world of fantasy, one-part completionist challenge, being such a difficult adversary, and one-part nasty surprise, because encountering one can only happen at a very inopportune time, right before another major boss fight.
It was deduced that the chances of encountering a Warmech on the sky bridge was approximately 3/64; which equates to roughly 5% of the time, but if you’re unlucky like me, you somehow manage to run into Warmech almost every time.
Anyway, there’s a sky bridge in my place of employment.
And there’s a Warmech that patrols it.
