I'd decided that if you wish to go this route, you may involve a Dark Evolution line to go along with the normal line of Evolution. Dark Evolution only takes affect from Perfect and up.

It just somehow popped to my head after just thinking the possibility of Dark evolution to have [url=http://wikimon.net/Death-X-DORUguremon]Death-X-Dorigure(Grey)mon[/url] (or just the [url=http://wikimon.net/DORUguremon]Regular of that[/url] if deemed more fitting) that would end in Megidramon. If any one of you wants to have either of those I'm not too picky with the line there being room to change.
(Example: [url=http://wikimon.net/Skull_Baluchimon]Skull Baluchimon[/url] -> [url=http://wikimon.net/Skull_Satamon]Skull Satamon[/url])
