A man of powerful presence, Gunther Davis is a bulky human standing at 6’7”. He has broad shoulders and clearly-defined muscle mass, but is also packing a bit of unnecessary weight. He has a bushy circle beard and a grade-three haircut, both instances being dark brown. He has notably hairy eyebrows and suffers from heterochromia – his left eye is a natural blue whilst the other is a discoloured milky-white. It is implied that he is partially blind in this eye.
Little is currently known of Gunther's life prior to G.U.A.R.D.I.A.N. save for the fact that he was once a Systems Alliance marine.
Gunther joined the G.U.A.R.D.I.A.N. Initiative and was assigned to Asgard Station as it's head instructor.
