Bro is Dave Strider's ectobiologic father, adoptive older brother, and guardian. He shared a fierce sibling rivalry with his younger brother and raised him harshly, to the point of his behavior being confirmed as abuse by Andrew Hussie. Though Dave imitated him and never questioned his methods, this idolship is broken as Dave matures and realizes Bro's faults, especially in raising him. In this respect his relationship with Dave is inversion of those of John, Rose, and to an extent Jade Harley with their respective guardians.
