Meet the Granddad of the Immortals. The Oldest member, not the founder but a sort of step dad that took the young Emperor and his Brother in when they fell to Earth, for more on that check the Wiki. Even then he was a warlord of some standing and taught the Immortals all they needed to start their rein of conquest. Some suspect he was once a Deadly Spaceman of renown before he came to Earth.
BIG "D" or BIG DADDY
He is the oldest, most mean spirited, wrinkled and wizened, whorey old taciturn tactician there ever was. Veteran of over a million battles. Grumpiest git that ever drew breath. Tough and resourceful with a temper of towering proportions...
Just a pity he's such a little shit.
While his military knowledge is genius beyond compare, it would be unwise to make any reference that draws attention to height, or dimensions... in brief he's a bitter little short arse. But cross him at your pearl, even the Maniacs sometimes remember to not say anything about his height. Most of the time.
Even though his once mortal body has been Immortalised he still suffers from respiratory problems from smoking so many cigars in battle. He prefers his old clunky re-breather to the newer more sleeker designs.
His face and body still bare the scars of war. His chest is resplendent with medals of honour. Most are for being a bastard.
