Oh man, I still remember when I came up with 'MolochMekkane' like it was yesterday, though it was at least 3 years ago, probably more.
Moloch is the name of an ancient Phoenician god, one that has a single all seeing eye, and terrifying power. He will not assist anyone without sacrifice, and had idols for it. A story goes that a village was about to be attacked by an advancing army, and the mothers of the village threw their children into one of the idols, which was basically a furnace that burned them all to ash. Moloch then killed the entire army in a storm. So, the first part is an all seeing, terrifying, sacrifice demanding old god.
Mekkane is something I came up with after playing Kirby Super Star Ultra. It came from one part of it where you go to planets. One of these planets, Mekkai, is actually a giant mechanical thing kind of like the Death Star but with an atmosphere. On the original Super Star it was Mecheye, don't like that spelling. Mekkai was so cool to me I started wondering if there could be a race of electromagnetic humanoids who actually lived on it, and if there would be some kind of monarchy. What would the name of the royal family be? I settled on 'Mekkane' because that sounded and looked so damn cool to me. So the second part is just from my own imagination.
You may notice neither of those things have anything to do with each other. I did and started saying them together, because it sounded cool to me. About the time I finally made a Steam account, when it came to giving myself an online identity, I put in 'Moloch_Mekkane' and then, now and forever, I am MolochMekkane.
Though it wasn't intentional, it has essentially come down to something like 'All seeing sacrifice demanding machine god' in the end, which sounds dark, and also funny because I made it up ('built' it.)
