Okay, here's a better version of my last post.
Allies:

Name: Arthur Bedivere Fredrickson
Powers/weapons: Excalibur (both the sword - which cannot break, and the scabbard, which means he cannot bleed)
Notes: the Main Character. Wears an eyepatch. Sometimes jumps into situations without really thinking about it - if you ask him for help, he'll help.

Name: Simon York
Powers/Weapons: He uses magic sometimes but rarely.
Notes: Probably one of the most important characters. He's a pacifist, kind-hearted, sometimes annoying. Intellectual nerdy type.

Name: Olive Blanche aka the White Knight
Powers/Weapons: Voulge, armour. Faster and able to jump higher than a normal human (like an anime character, not like Action Comics #1 Superman).
Notes: Blonde hair, brown eyes. From Quebec. Prickly and easily annoyed. Rather slim for such a scrapper.

Name: Susan Scott aka Lady Shield
Powers/Weapons: superpowers, no weapons
Notes: Brown hair, blue eyes, great... tracks of land. Australian. If this were a Five Man Band, she'd be the Chick - at first glance. But don't underestimate her.

Name: Jack Fox aka Blue Barricade
Powers/Weapons: superpowers, no weapons (and yes, I am being purposely obtuse, I do know what their superpowers are)
Notes: African American, from a north-eastern state in the USA. Essentially easy-going and perceptive, he sometimes says the wrong thing, but is still a nice guy.
Name: Lieutenant Ralph O'Brien
Powers/Weapons: Military standard equipment, no powers
Notes: He's the military liaison and Jack's best friend. Normal, but has a strange obsession about his scarf. You're better off not touching it.
Axis:

Name: Sir Seraphin
Powers/Weapons:
Notes: The German Counterpart to Arthur Bedivere. He has straight flat black hair and a monocle. Not technically a member of the Nazi party, he has a strong sense of honour and is obsessed with protecting "his people".

Name: the Prussian
Powers/Weapons: Guns. He likes guns.
Notes: He's the one on the first page pointing a gun at Bedivere. Devoted to the Nazi party and Germany - despite considering himself Prussian (Prussia founded the German Empire in 1871, and "Prussia"'s status within Germany has been confusing ever since. In other words, I need to do more research).
Name: Dr. Diederich
Powers/Weapons: See notes.
Notes: Nazi Scientist, he keeps on inventing stuff - weapons as well as other things. Wants to keep the Hitler legend going. Knows a lot about Cloning. Wears itty bitty spectacles.

Name: The Black Knight
Powers/Weapons: Twin axes
Notes: In German tradition, the Black Knight was the hero. She is a firm member of the Nazi Party, but not necessarily the people within the nazi party. She is usually annoyed and condescending, or angry and condescending.
Other:
Name: Morgan(a) le Fay
Powers/Weapons: She's quite an accomplished sorceress
Notes: She mostly lives with the Faeries, but there are ways to contact her. She has a strange sense of humour, and spends most of her time nowadays playing poker.
