Breaking Bad & Better Call Saul: Every Character Ranked Worst To Best

Brought in by Gus to help Walt with work in their new super-lab, Gale Boetticher isn't like the usual customer to make their way into the Breaking Bad's seedy criminal enterprise.

Incredibly upbeat, approachable and naive, his involvement in Gus's empire is both mysterious and amusing, allowing actor David Costabile to play one of the show's most purely entertaining and brilliantly misplaced characters right into the centre of the action.

Eventually ordered to become Walt's replacement, Gale - despite his chosen vocation - quickly becomes a colossally tragic figure, and yet another haunting reminder of the damage Heisenberg can cause. His singing will be missed forever.
