Well, I've certainly heard my fair share of unusual names, both in real life and in other properties (Final Fantasy, for example), and the last thing WCL is meant to be, is realistic.
The dark glow's whole point is that it's meant to be dark.
I was thinking ditching the color completely and making it more like a total black mist. It's easy enough to experiment with it since the file is still broken into layers.
As for the call signs, as I said, they're emphasized far more on these cards than they are in the story. The characters actually rarely refer to each other by the call sign names; they're merely for designation during the announcements and what not. It's almost more like the suits are separate from the characters, kind of like a Gundam character's mobile suit has a name and then the rider has his own name. It's not "Reynaldo Hart is Vampire", it's more like "Reynaldo Hart is equipped with the Vampire WEAPON." Although during the competition scenes, the announcer does often say "Reynaldo Hart also known as Vampire". It's...complicated. I'll have to post a chapter of the story to make it clearer.
And yeah, I considered the Beast character, of course. I'm no stranger to Marvel comics characters, and I thought that through already years ago when I first made the guy up. I decided that it was just going to have to be that way. There simply isn't a better word that suits the character and I'm not about to rewrite him so he's not that animalistic type--the story is way too far along for that.
Not being a big comic reader, I just came up with simple handles that suited the characters, but others were connected to mainstream comic characters as well. There was a speedster WEAPON named Impulse that I ended up changing to the much less impressive Dash, and there was Graviton that I changed to a more fitting, but less descriptive Dominus. But Beast has always been that problem name. I always figured some would make a ruckus about it--I just decided that I wouldn't worry about it because I gave up on trying to come up with a replacement name years ago--suitable replacements are either lame or also connected to mainstream characters. Just going to be more than one Beast character out there until I can think of something better, and hopefully the fact that Renard isn't one of the most prominent characters in the story will keep his call sign from being too big a deal. If I get sued or something (highly unlikely), I'll cross that bridge when I come to it. Meanwhile, I'm going forward with my project.
