Expose your bottom to people but just don’t do it in the dark. You cheeky monkey, you!

I wear a crown, but I’m not always royalty. On a chessboard, I’m the strongest of my kind. In a deck of cards, I stand beside the king. Bees have one of me, ruling the hive. In a kingdom, I’m a woman of power. Who am I?

I bring people together, usually by making them throw things at each other.

Roses are red, green means go. I’ll never change, so some don’t know. Even if I’m hidden in thicket, Don’t ignore me, that’s the ticket!

A pale blue hue, cast over the night. Depending on the calendar I might be bright.
