Lavos Spawn, from Chrono Trigger on the SNES, fought at Death Peak in 2300 AD!
Should probably print without supports on FDM, but don't quote me on that! I tried to model it to keep the spikes from having any extreme overhangs.
When printing in resin, it's a good idea to hollow out the model in Chitubox/etcetera to save material, and be sure to support the interior.
