How I Met Your Mother: 10 Worst Characters Who Appeared After Season One
3. Brad Morris
Debuting in the second season and recurring on-and-off throughout most of the show's run, Brad Morris was actually quite a fun character during his early days, a law school friend of Marshall's whose personal woes led to some top-tier humour.
The storyline where he befriends Marshall and they start accidentally almost-dating is comedy gold, but Brad as a character quickly lost his edge. During his sparse appearances, his very existence became something of a punchline to a terrible joke.
Between bailing from Marshall's bachelor party and going out (briefly) with Robin, Brad soon grows into a calculating, unlikable corporate lawyer who almost destroys Marshall's career.
Watching him turn from lovable side character to slimy villain is tough to see, especially because no part of his development feels in any way organic or explained. He's just a walking plot device, and a tragic waste of potential to boot.
