Tennant appeared as the Doctor between 2005 and 2010 and was succeeded by Matt Smith, but it seems as though he's still missed by fans after a recent poll from the Radio Times found he was the most beloved Time Lord ever.
Smashing tough competition from Tom Baker, Jon Pertwee and more recent Doctors such as Christopher Eccleston and Jodie Whittaker, Tennant scooped 10,518 votes from almost 50,000.
Hot on his heels was current Doctor Jodie Whittaker who had 10,423 votes, while Peter Capaldi came in third place with 8,897 votes, Smith had 7,637 and Baker 3,977.
On the other end of the table, Peter Davidson pulled in just 351 votes.
Despite no longer appearing as the character on the small screen, Tennant has voiced the Time Lord in several Doctor Who audio dramas, the most recent of which is a new series called Dalek Universe.
Speaking about the upcoming project to Radio Times, he said: "It's a big old epic sweep. It reminds me a little bit of those Flash Gordon serials that used to be on the TV during the school holidays when I was a kid.
"Each story has its own self-contained world, but the whole thing has an over-arching momentum. I've really enjoyed how varied it is, all within this one story, and the variety of worlds that we go to and environments that we're in.
"And, as we go through this space opera, to have all these characters brought so clearly to life by a whole range of wonderful actors, it's been a treat."
Tennant recently took part in a lockdown video call with fellow Doctors Jodie Whittaker and Matt Smith, where he revealed what it felt like to play the iconic character.
He said: "I think growing up in Britain you're very aware Doctor Who has been ubiquitous for all of our lives.
"Even when it wasn't on TV, it was still one of those sort of cultural things."
Before adding: "When you realise it's your turn, you do know what that means in terms of a loss of anonymity and the fact that the first line of your obituary has almost certainly been written.
"But it's a huge privilege and also feels very precious, because people love it so much and carry it with them throughout their lives.
"To be the custodian of that, you just don't want to break it."
