Some of the best TV shows - the ones that eventually soar to critical acclaim and garner millions of die-hard fans - don't always hit the ground running. It can be pretty hard to find your footing that first year. In fact, there are a lot of TV characters added after Season 1 that went on to become integral to their shows.
One of the most tried and true methods that showrunners use to stabilize a shaky first season is introducing new characters. A new character can energize a lagging plot line, or even lead to a new plot line entirely, taking the show in directions that may not have been originally intended.
Not all new characters work. Many are summarily dismissed. But some of these new characters feel so enmeshed in the fabric of the show, it's hard to believe that there was a time when they weren't a part of it at all.This is a list of the greatest television characters who weren't in the first season. Vote up the series regulars who became most integral to their series. And if you don't like the order this list is in, feel free to rerank it. In fact, it's highly encouraged. Make your voice heard for the best TV characters who weren't in Season 1.
