I, too, am a Megas devotee, though for me it's impacted mood more than characterizations per se (I write X-series stories). I think it's clear that you had a lot of fun with Crash Man. His characterization flows quite naturally. And the introduction with X seems a foreshadowing to an epilogue matched to "Lamentations". This is well-executed thus far for the type of story that it is.

I think you compliment The Megas idea of Air Man very well. I hope to see more in the near future.

Haydain's Heat Man would be better for this.
