Man o’ war
When an animal also goes by the floating terror, there are going to be a lot of expectations on it. Will the man o’ war live up to either of its dramatic names? You be the judge.
The man o’ war is equipped with a venomous sting.
It has an extremely limited capacity to move itself. It floats on the ocean surface, subject to the whims of the winds and waves. It can manipulate gases inside itself to sink a little and use a “sail” on its body to give itself some direction. That is better than a stupid plant, but pretty pathetic for an animal.
Number of legs
The man o’ war particularly despises the blanket octopus for its immunity to its venom, the loggerhead turtle for having skin too thick to sting (and for eating the man o’ war on the regular), and Meghan Trainor for canceling her planned concert in international waters in the mid-Atlantic. To a lesser (but still substantial) degree, it also hates everyone who has ever lived.
What is its secret?
The man o’ war’s deep secret is that it is not actually a single organism, but instead a colony of specialized “zooids” which cannot truly function individually.
What if it fought a bear?
That bear’s getting stung. Unless the wind gently blows the man o’ war somewhere else.
Is it noble?
It planned on trying to sting Meghan Trainor; I just know it. Fortunately for her and all us would-be victims, its aggression is balanced by its inability to move sizable distances with purpose. It is by far the animal most like if a piece of day-glo driftwood was holding a poison-tipped shiv and seethed with hatred at all life.
