I've gleaned these from the pages of Hellboy comics and from Rasputin's diary which was included in the Director's Cut of Hellboy, the movie. These are purportedly they symbols early alchemists used as they sought the secrets of the universe.
Why are they here? Well, much of THE PHANTOM CLAW revolves around the use of Vrill Energy and the "mecha-glove" that Rasputin used to summon Hellboy. Although he wore two gloves in the comic, Mike liked the comparison with the Right Hand of Doom that Guillermo used in the movie so we'll have Rasputin use just one in the animated universe as well. Anyway, the glove is still intact!
When the glove is activated, electricity will arc around it but this technology combines technology AND the occult. So image little electrical effects that form mystical symbols in the air before disappearing. A cool idea from Mike that I think we should be able to carry off.
But that's not Vril. Vril is an unlimited energy source that bounces in and out of stories of Nazi mysticism. You can read all about the book that first popularized Vril on Wikipedia. In our universe, it is the energy required to bring Hellboy to earth and is sought after in the present by Von Klempt, Zinco and Rasputin, and each has his own plans for it.
And my plan is to illustrate that energy with the fabled "Kirby Dots." Click on that for an explanation on how to draw them in comics, courtesy of PencilJack. The start of my own notes on that are below. The key is to remember that the dots are negative space, not the shapes to be animated. If you focus on the dots you'll get animated balls where really it's just sort of a texture to the energy. I sense a future production headache right there. Later -- Tad
