Jon Umber

The Greatjon is exactly the sort of lord his epithet promises: enormous, loud, and given to declarations of loyalty voiced at a volume that leaves little room for doubt about his sincerity. He was the first of Robb Stark's bannermen to hail him King in the North, drawing a blade over the matter of protocol before the room settled on crowning the boy rather than fighting about who got to name him something else, a scene the North still tells with some relish. Lord of Last Hearth and head of a house nearly as fierce as the giants its sigil evokes, the Greatjon's loyalty to House Stark runs deep enough that he is reported to have fought eight men at once rather than yield quietly when the Red Wedding turned to slaughter around him. A maester notes that a lord this difficult to subdue is precisely the sort an enemy prefers to take alive rather than kill outright.
