The 100 Cast Then and Now: Season 1 to Season 7

These kids have really grown up!

The 100 Cast Then and Now

It feels like just yesterday we were watching the pilot episode of The CW's sci-fi series The 100, as a group of seriously underprepared juvenile delinquents were sent from space down to a radioactive Earth. Now, here we are seven seasons later watching fully-grown adults face bigger and badder obstacles all across the galaxy! 

We can't help but get emotional when reminiscing about all the ways Clarke (Eliza Taylor), Bellamy (Bob Morley), Octavia (Marie Avgeropoulos), and the rest of the gang have grown and changed over the years, which is probably why we made this "Then and Now" gallery. And yes, we've thrown in the rest of the cast's first appearances -- from Lindsey Morgan's early in Season 1 all the way to newbies like Lola Flanery who have only joined recently.

From their first appearances on the show to their Season 7 debuts, take a trip down memory lane and scroll through these photos of The 100 cast then and now!
