I am green in the fields, black at the market, and red at home.

I'm a creature of legend, a mysterious sight, With wings that glow, in the darkness of night. I'm a harbinger, of disaster's approach, A West Virginia legend, with an otherworldly broach.

I can be very cute, but I cannot avoid puncturing you if you scare me. You might see me in a in a videogame with rings.

I speak in colors, I cry in shades, I disappear when the sun fades.

I make sirens wail a different tune, A cosmic shift that colors stars maroon. Astronomers love me, so do the docs, Guess my name, think waves, not clocks.
