Ignacio is a surly and cynical man with an unhinged temper, who isn't hesitant on giving threats to those who pester him. Likewise, he despises confrontation which he either retreats to his house, or even violence at one point as shown with him shooting Moloch on Hollow Sorrows apathetically. The moral of the story, don't make him angry. Oh, and he's most definitely American (he owns a gun in a place where it's illegal to have guns)
