It's completely useless in terms of theme and such, but it has the same powerful ring to it as Inferno and Colossus. It's certainly better then "Edge" which wouldn't have had that impact.
Colossus and Nemesis Inferno are very god-like, powerful names. They envoke all those ideas of superiority. "Stealth" does as well, it's just a shame they couldn't think somthing up that actually matched the theme.
It's a bad name. It's not quite crap, because it's got a powerful ring to it. But it makes no sense.
