Warning: black/green/red Blood. Mecros got stabbed by the only weapon that could leave a cut. Not much blood, trust me. (She was just getting back after going to an event {probably Minecon [I wanna go so bad one day]} and Darkness tries to kill her.)

Voila:

The sword is actually black and coated with some sort of poison that won't affect Mecros, even though Darkness thought it would.

Darkness' reaction:

I didn't try too much. I freaking used crayons (and sharpies) XD
