An energy line, the energy given out keeps creating black holes (Not real black holes, I know a lot about them, I call them a black hole because they are holes and they are black, not because they are a huge ammount of gravity, if I wanted to draw a realistic animation I'd just draw a black screen since the light can't escape).
A fairly bad sword animation, he's hitting it on concrete so there are sparks :O (Even though I didn't draw a floor nd the sword goes below his feet, which are the floor level... meh)
