Life's Champion

Life's Champion was a title applied to the Eighth Doctor on multiple occasions.

Joanna Harris greeted the Eighth Doctor with the title. (PROSE: Vampire Science) When repelling a Ice Warrior invasion, the Doctor included "Champion of Time and Life" among his titles. (PROSE: The Dying Days)

Later in life, the Thirteenth Doctor was the champion for life more generally, when Tecteun released the Flux to destroy the universe in order to rid the multiverse of the Doctor's influence. Azure could not the Doctor's commitment to life, as just one form for matter, but the Thirteenth Doctor explained it well: "Life must win, because otherwise, why are we here?" (TV: The Vanquishers)
