Uhm, yeah, no. Black holes ATTRACT, they don't REPEL. Ruby is obviously thrust away from the blast when she fires, not pulled towards it. So not a black hole.

I would say the symbol basically means 'Super Thrust'. Rather than it being a black hole, the round circle is the bullet, and the arrows are indicating that the round provides massive thrust.
