Update - 27 Dec 2020
Ok, so here's the first update.
My idea is based somehow to mr Steven Kippling suggestion, but I basically reversed it.
So, instead of coldtype Hydra, that lives under the frozen lake, and cyborg that is "fiery" in nature, I made Hydra living in a very dangerous place, full of lava, and so hot, that can even live under lava lake. :)
Our cyborg will be sort of electricity cold driven technology, but still haven't started effects on him yet.
Software 3DS Max + PhoenixFD + Tyflow.
I'll probably use FumeFX for the fire breathing sequence of the Hydra.

Ok, decided to start this awesome challenge.
Finally, I don't have to worry about animation and models while doing tests, and I only need to do the effects.
Hopefully I will learn and share with community, and at the end of the challenge, I'll be much more experienced.
Good luck to all. :)
