10½ Best Male Companions In Doctor Who History
9. Wilfred Mott - Bernard Cribbins

So Wilf only appeared in a few episodes, including some in which he served a greater role as companion Donna Noble's own hometown supporting cast. No fan of the show, however, can fail to see the way the old guy nearly steals the show from David Tennant's bombastic and often desperate Doctor, no less in every scene he's in.
First appearing in "The Voyage Of The Damned" as apparently a sort-of Greek Chorus-type figure, Wilf's first meeting with the Doctor would start a thread weaving through the 10th incarnation's story line that kept viewers as entertained as interested. By the time he actually boarded the TARDIS, perhaps no Earth-bound Doctor Who character since the UNIT days had earned such a following.
From his defiant stand not to remain in London despite the recent Christmas curse which always seems to bring alien invasions to the city to his pleading with the Doctor to save himself and to hell with fate, Wilf was one rock of steadfastness despite his intermittent poppings up in the Doctor's life.
Add his standing as the oldest-ever companion, his intimate connection with the Doctor in The Greater Scheme Of Things and his still side-splitting line "God bless the Cactuses" in "The End Of Time," and Wilf is truly one for the ages.
