Siegfried

When he is outside of his Armor.
You see a large man that is easily 6 feet tall with broad shoulders and defined muscles of a main that was trained for combat. He seems to be in his early twenties. He has piercing green eyes and platinum blonde hair with a noble vintage

At the moment he typically wears his Arming Doublet and padded trousers when out of his armor. His Honedge and other capture crystals are always nearby.

In his Armor
He is covered head to toe with heavy armor. His helmet is completely face concealing and is forged with the Shape of a snarling Dragon that radiates menace and terrible power. His left arm has an oversized Gauntlet that articulates as well as his actual hand. It seems to be made of a bright silver metal. The Armor itself  is obviously well made it is currently painted Red and White to denote him working as a Legion Auxiliary.
