This is how a real beyblade battle is carried out ... in the imagination of a 6 year old. Or at least that is how i pictured them when i was younger (about 10 years ago !).

To get the "epic clash" effect: I used 2 halves of a sphere, then deformed and textured them using weight maps,morphs,the node editor and a lot of gradients and procedurals;

I used an effector to appear as if the fire is "digging" into the more blueish watery energy.
For the effect from the background i used a simple point light with lens flare.

EDIT: i have unplugged the luminosity so that you can see the deformations, otherwise it would have just been a white surface in open gl.
