"That One Boss"

[Bob Schroeck]

So I was doing my daily maintenance over at All The Tropes and when I noticed that the trope "That One Boss" had game-specific subpages I ended up wondering which bosses in COX would count as "that one boss".  For those who don't want to bother looking it up on the wiki, the core of the trope is:

And then, there's That One Boss, the boss that falls victim to poor playtesting. You're levelling up normally, plowing through every battle, until you reach this particular battle and suddenly meet a plethora of Game Over screens. Eventually, you Rage Quit, or you go on the Internet looking for assistance. In the event that you stop by the game's message board, lo and behold, everyone else is having the exact same problem, with entire topics asking "how do I beat That One Boss?". Walkthroughs usually list the worst offenders as "the hardest boss in the game", and eventually, such a beast receives a reputation for being just that freaking hard.

So... honestly, over the years, the community gets better and better at dealing with the various villains and archvillains, but I would say that when the Imperius Task Force was first released and for at least a year afterward, Romulus was such a boss.  I'm sure there have been and/or are others.

What was -- or is -- "That One Boss" for you?
