Behind every great incarnation of the Doctor is a fierce companion along for those epic adventures through time and space. Doctor Who's eleventh season is no exception to that rule and Jodie Whittaker's delightfully optimistic Time Lord has taken on three new companions, each with their own reasons for hopping aboard the Tardis.

For Yas (Mandip Gill), it,'s an opportunity to be a part of something greater after finding herself stuck in her current job. For Graham (Bradley Walsh) and Ryan (Tosin Cole), the new adventure means not sitting home consumed with grief after losing their loved one in the season premiere. They follow in the footsteps of a sidekicks like Donna Noble (Catherine Tate) and River Song (Alex Kingston) who, through their many travels, have helped the Doctor better understand humanity while also creating some unforgettable memories.

With so many companions to choose from, it can be hard to figure out which one suits you most. But don't worry, we've got your back! Take our quiz below to find out which Doctor Who companion you are.
