Don't go into the light
Do you have any self imposed rules or tips you keep in mind while making art or are you the type to start a piece without any solid direction and see where it takes you?
I think a fully organic Megalon is the way to go. Could even make for a fun interaction during their initial conflict where Gigan attempts to shut down what he assumed to be Megalon's many body mods, only to realize Megalon has been keeping up with him through brute strength alone.
If not, then his drill arms could vibrate at a high speed rather than spinning. What do you think, yes or no to cyborg Megalon?
Do you think Megalon should be fully organic or would he have a few cybernetics enhancements? If so I'd imagine Megalon being on the lower end of the cyborg spectrum, with characters like Gigan being much higher with more than half of their bodies being modified or replaced entirely.
Appropriate that she would get frozen in ice
I've never been the biggest fan of MUTO Prime's official design, from her weird Megatron face, to those crusty Cheeto arms, and the overly armored body. My biggest issue with MUTO Prime is just how far removed she feels from the original Male and Female MUTO.
