More of TV's Best Cast Additions Ever: Readers' Choices From Grey's, Lucifer, Schitt's Creek, Always Sunny and More

Earlier this month, we made a list of our favorite TV characters who joined their shows late — but that, as it turns out, was just the tip of the iceberg.

Our original list (which you can read here) collected our picks for the most memorable cast members who actually didn’t appear on their shows until after the first season — and though we tried our best to be comprehensive, we admit we may have missed a few. Thankfully, TVLine readers were there to make some great suggestions, and honestly, we’re kicking ourselves for letting some of these slip through the cracks. So we’re proud to present a fresh list of reader-submitted favorites from long-running dramas like Grey’s Anatomy, Supernatural, NYPD Blue and NCIS and from classic comedies like Schitt’s Creek, It’s Always Sunny in Philadelphia and That ’70s Show, just to name a few.

Read on to see even more of the best characters who came in late (Season 2 or beyond) but still became essential members of their shows’ ensembles, all of which came straight from you. (Thanks again for that, by the way.) And if you’ve read both lists and still aren’t seeing your favorite cast addition? Well, that’s what the comments are for.
