sidekick

Kenzi from Lost Girl

Serving as Bo’s sidekick, sneaky Kenzi Malikov (Ksenia Solo) has more to offer than most people give her credit for. This gal has delved headlong into the Fae world and hasn’t looked back since.

Amy Pond

After first meeting the Doctor when she was seven, Amy Pond (Karen Gillan) thought for years he was an imaginary friend. Until he showed up again the day before her wedding and it turned out her Raggedy Doctor was really an alien Time Lord (tangentially, what is up with the Doctor and redheads’ weddings?).

Donna Noble

Accidentally drawn onto the Doctor’s ship on her wedding day, Donna Noble never thought she’d see the lonely alien man again. But unable to get him out of her mind, she began searching for him wherever something strange or paranormal cropped up, eventually joining him as a full-time companion.

Martha Jones

Companion to The 10th Doctor, med student Martha Jones didn’t exactly expect her life to be interrupted by an alien in a blue box. Nor did she realize following him on a whim would lead her on a universe-spanning adventure and give her the skills to save the entire world.

John Watson

Sherlock Holmes’s flatmate and blogger seems harmless enough when you first meet him, but don’t let the frumpy exterior and questionable taste in sweaters fool you. Underneath the plaid and knits is a sharp-eyed ex-soldier and adrenaline junkie who loves the chase almost as much as his partner-in-crime-solving does.

Joan Watson

Elementary’s Watson may be a Joan instead of a John and traded in a soldier’s firearm for a sober companion’s exasperated patience, but don’t underestimate her. She not only keeps up with the deductive skill of Sherlock Holmes, she does it all while running around New York in two-inch heels.

Rose Tyler

Rose started out as a normal nineteen-year-old shopgirl until the Doctor blew up her shop (there were Autons inside at the time – don’t ask). But given the choice between an ordinary life and adventure through all of time and space, Rose chose the latter. Hey, who wouldn’t?
