Oppie Seville, codenamed the Red Giant because of his armor's color, is a Spanish Fighting Bull and retired weapons master of the Inquisition. He is also a former crusader in service of Kreszentia Kardos. He taught Kingman how to fight using blends of close quarter weapons and firearms. And was the one that suggested Kingman use a shotgun and later grenade launcher because of the cat's crappy aim. The reason why the Inquisitor is as agile and deadly as he is with the Lucerne Hammer and shield is because this is the guy that taught him how to use it.

As far as Oppie Seville himself goes, he is, like many members of the Inquisition's military arm a product of Project Orphan, adopted from a Catholic orphanage in Seville, Spain (where he gets his name). His acromegaly made him grow to an enormous 7' 10" in height, in order to keep his body fit and agile at his size, the Inquisition had a experimental procedure done to him, that caused his bones to nearly quadruple in strength, and form a second heart to deal with his body's need for pumping blood. In combat he wields a targe shield with hidden 'spurs' on the sides and a spike launcher hidden in the center he also wields an enormous Estoc. A sword made for powerful thrusts that can crack through thick daemon chitin. In ranged combat he is known to wield a 37mm autocannon.

He retired after Krezentia's brother led her and her retinue (including Oppie and Kingman) into an ambush. His back was broken protecting his wife Tori with his own body and getting her to safety with hordes of daemons tearing at him.

He now lives in Ireland with his wife and offers to train any would be modern day fencers, with preference to Inquisition applicants. Though his wife is pushing him to become an instructor with the BOS.

He also loves to cook as a hobby.
