There's not enough of non-fantasy Onyx pictures and so I present this!

Looks like Onyx is providing overwatch but something has caught his attention and he is prepping for potential combat by loading a bullet into the chamber. As he keeps his eyes forward, the distant sound of thunder can be heard as the clouds roll in.

I do like this one a lot. It's as if the rain will hit just as the battle will start. A fantastic, if a bit cliche, setting of weather but I love it nonetheless!
