Which Doctor Who Companion Changed The Most During Their Adventures?
Some may have had longer stints on the show than others, but all went through some serious developments on their travels with the Doctor.
Rose Tyler (Billie Piper)
Rose certainly had one of the longest arcs on the show and one of the deepest relationships with the Doctor.
Jack Harkness (John Barrowman)
Oh Jack. He definitely became a bit more serious due to his time with the Doctor (especially Nine).
Mickey Smith (Noel Clarke)
From semi-male-damsel-in-distress to a hell of a guy. No doubt time with the Doctor improved him.
Donna Noble (Catherine Tate)
The Most Important Woman in all of Creation. It doesn't get much more impressive than that.
Martha Jones (Freema Agyeman)
Martha became stronger and infinitely more independent after her time with the Doctor - and more badass.
Sarah Jane Smith (Elisabeth Sladen)
Okay this one is cheating as Miss Smith was present in the first series - so she may have changed most.
Wilfred Mott (Bernard Cribbins)
Alright, he may not have been a full-fledged companion, but Wilfred is a true shining star of the series.
Amy Pond (Karen Gillan)
Between her time with the Doctor and with Rory, Amy Pond's life was constantly ups and downs.
Rory Williams (Arthur Darvill)
Okay physically, we have to say, Rory grew up a LOT. More mature and a bit more adventurous...among others.
River Song (Alex Kingston)
No doubt, River Song is one of the craziest and most delightful people in the Doctor Who universe.
Clara Oswald (Jenna Coleman)
The Impossible Girl spent time with both Eleven and Twelve and had very distinct relationships with each.
