Oh, and here’s a gorgeous poster promoting Season 5.

The 100 Season 5 Villain

The 100 Season 5 has cast William Miller as the season’s Big Bad. According to TV Line, the Spanish actor will play Robert McCreary, a mysterious prisoner aboard the long-distance mining mission sent from our time. A former enforcer from a powerful crime syndicate, his ruthless, violent methods make him a formidable antagonist to our heroes.” Watch out, Clarke!

The 100 Season 5 Cast

Ivana Milicevic (Love Actually) is Charmaine Diyoza, one of the “mysterious criminals” on the prison ship we see in the final moments of The 100 Season 4 finale. Milicevic will be a recurring guest star, so look for her to stick around for at least a few episodes.

According to Entertainment Weekly, Charmaine is a “ruthless military strategist who will go head to head” with our already established characters. Sounds like a worthy adversary for Clarke.

Jordan Bolger (Peaky Blinders) has also joined the cast in a recurring role of Zeke Shaw, an adrenale junkie “brimming with brains, wit, and bravado.”

In other casting news, Tasya Teles (Echo) has been upped to a series regular, and Madi, Clarke’s “daughter,” will now be portrayed by Shadowhunters‘ Lola Flanery.

According to Deadline, Shannon Kook (Shadowhunters) has been cast as a new character, set to appear in the Season 5 finale. The most interesting aspect of the casting announcement is that Kook’s character has the potential to continue on into Season 6. Not many characters on this show get the assurance that they will survive the season!
