Made this while spending a couple hours learning how Zbrush works.
Energy ball (or ki blast effect) you can print for your action figures. I've yet to print this, but Cura shows no anomalies and sliced the model just fine, so there shouldn't be any problems.
I've also included the OBJ file in case anyone else wants to do some edits of their own to it.
It would probably look best if you print this using a clear filament and then paint it using transparent colours like Tamiya Clear acrylics.
UPDATE 1: Added a hollowed out version of the ball.
