Yes, I found a found a bounty named Megas (with a non-English last name). (Ugly purple-haired dude with an implant.)
In-game, my character is not named Megas, but War (after the NetHack player character, who is supposed to be the fourth rider), although since my current character portrait is the Doomguy next to Hegemony Ryu, I should have named him Doom, or Doomguy.
I do not think having War or Warmonger as my forum alias my be a great idea. I just defaulted to Megas. Could not think of better at the time.
If I pick the Tri-Tachyon power ranger, I name him Blue.
There is that new female spaceman portrait (more like fighter helmet). Could name her Ninja.
