In the Firefly series, River Tam is on the run from the Alliance with the help of the Serenity crew. She possesses both lethal and psychic skills which make her a powerful weapon that the Alliance wants back at all costs.

Nicknamed “Wash”, Hoban Washburn (Alan Tudyk) is the comical pilot and husband of Zoe Washburn on the TV show Firefly. He acts as the easy-going mediator and voice of reason to the rest of the cast, hesitant to run into dangerous situations and often found playing with plastic dinosaurs on his dashboard. He dresses as mellow as he acts, in coveralls with a Hawaiian shirt over top.

Buffy is a cheerleader turned butt-kicking slayer who found a home in Sunnydale, right on top of the Hellmouth. When she’s not taking out vamps or other nasties, she loves spending time with pals Willow and Xander or training in the library with Giles. Everyone knows (even vampires), if you’re smart you’ll be sure to side with The Chosen One.

In Firefly, Kaywinnet Lee “Kaylee” Frye (Jewel Staite) is a wholesome and happy-go-lucky crew member of the Serenity. She may be a natural mechanic, but that doesn’t mean she isn’t in touch with her feminine side, as seen by her colorful parasol and patches.

Mal Reynolds is the captain of the Serenity crew in the Firefly series. Despite his tough guy exterior, he really has a heart of gold. He helps River and Simon Tam hide from the Alliance, even if it means putting himself and his crew in danger.
