Pseudonymn reminds me of Stan Lee. Kindly and wholesome like your favorite grandpappy, great zany sense of imagination but with a seedy 70s moustache and liesure suit that makes honest folks uncomfortable.
Darkstorme I see much like the Black Hand Adventure Club leader from Knights of the Dinner Table who rules the gaming table with an iron fist of logic. He'll let you try anything you want, just don't complain if it comes back to bite you in the kiester hard.
Makashi is like the wild Ronin of the bunch who honestly gets what playing an evil PC is like and isn't afraid to offer those types of players morally questionable situations to help gain in powers of the light and dark side. He's kind of like Darth Traya in that he seems neutral, but secretly you know he's rooting for evil and basking in your character's choices of corruption.
Leanther reminds me of the lead GM from Knights of the Dinner Table. Really nice to all the players, encourages them to roleplay to their fullest, yet you can almost hear the forehead smacking the desktop when that one player decides to charge the main plot NPC on impulse. My only complaint is that he doesn't use the kill wand nearly often enough, heheheh.
Mixafix/The Stranger is right up there in whackyness and humor with Pseudonmyn. One of those GMs that doesn't mind the main plot going offtrack a wee bit to engage in some hearty RP dialogue and jesting. Used to be one of my favorites, but haven't managed to sign up on one of his quests in maybe over a year now!
