'The Walking Dead': 16 memorable 1-episode characters

To celebrate the Oct. 22 Season 8 premiere of The Walking Dead — the series’ 100th episode — Yahoo Entertainment will be posting a new TWD-related story every day through the season opener.

With a deep bench of talent like the cast of The Walking Dead, it’s no small feat to make an impression with just one appearance. But that’s exactly what these TWD characters did, leaving us thinking about them seasons after, in some cases, they stole a scene. From the last real scientist (sorry, Eugene) the survivors meet to the endearing woman who’s smart enough to be afraid of a damn tiger, here are 16 characters who made a lasting impression with just the briefest amount of screen time.

The Walking Dead Season 8 premieres Oct. 22 at 9 p.m. on AMC.
