Mr. Jellyfish

Five Sentence Fiction from Lillie McFerrin Writes.
This week's prompt word is 'villainous'.

I first had visions of villains in black masks leaning over damsels tied to railway tracks.  But then I experienced a jellyfish in human form which felt much more villainous, and tried to put into words what the encounter was like. I tried it as a story but it remained fragments that I've assembled into a sort-of-poem.

He floats along on currents of impulse,
No hint of intent or purpose.
Though he seems so benign, approachable,
His words sting where they land like a tentacle.
When I try to describe him
I know there's something he's hiding
'Cuz he's shifty and shapeless -
It's hopeless.
He tries to draw me in
With his charm and a grin
But it's nothing, it's empty -
I'm prey.
I try to be small, not moving at all
'Till he decides I'm no fun and moves on.
