Squid.
Giant squid, to be precise. You see, unfortunately, there is a dangerous world out there. And while it is very likely that I shall never find myself in a situation where I'm alone with a deadly predator animal, there are certain things you have to be worried about just a little. It came to me during a show determining the world's largest eyeball that should I ever find myself in close proximity of a giant squid - the winner of the largest eyeball challenge, I'm afraid - there would be no end to how fucked I would be.
Let's examine. I don't have a proper phobia. I've eaten squid and most squid I will ever encounter in my life will be highly-destructible by my human muscular prowess. The reason I shall be entirely doomed upon meeting a giant squid is because of everything that goes with it.
{1} The setting would be underwater, or at least somewhere ocean/sea-related. From what we know of the giant squid, they prefer the deep ocean, hence why rarely we see any. Even still, I'm a lousy swimmer by any account. CAN swim, but somehow I managed to move backwards during an ordinary doggy-paddle. Even still, the average human being is not - per se - agile in water, and I am average, physically. In any case where movement is hindered, senses dulled, and air is dolled out not as immediate availability but by supply or by fighting for surface time with gravity, such a situation would be very nightmarish.
{2} On the other end of things, the squid is - of course - built for the sea, to the point where his natural enemy is the whale. There's proper evidence suggesting the two try to kill each other every chance they get, so what chance has a human got? They propel themselves by tentacle-motion of liquid jet-pressure as needed. And as for just motion and reaction time...they can really move and snap at something so fast down there... The suction-cap-laden tendril is on you before you realize it and the beaker lies ready to start chewing with intense shell-cracking pressure.
{3} There's also the mind-state. Here you are, intelligent human, when suddenly you notice...there's this aerodynamic thing of flesh moving this way. Kind of big too... Here's a thing. You're shocked or maybe even in awe of this thing. And then you take a look at that unblinking, staring, eye of his. Either one. That's the glaring eyeball of a total uncomprehending animal. If it is glaring at you, you're dead because you're food and entirely vulnerable. Many things in wildlife are vicious, yet may leave you alone if you...catch them soon after they've eaten, pretend to be subserviant, are not interesting enough, and so on. They'll decide not to bother. Squid? Erm...they seem much less complex than lions and tigers and bears (Oh my!). I think they'll just go after you regardless if they find you and think you look tasty.
