When I first came up with the design, I made it for a possible Heisei revisited comic. But the Showa origin was cool as well, and could easily work today. I would get rid of the beam weapon though, I always thought it seemed out of place. I would then make Hedorah able to whip acidity pieces of himself at his oppenent, like naplam, as well as a vomit forth a spew of gooey like acid, not like Biolantte, more gooey, toxic and disgusting.
