Mulberry

From Tardis Wiki, the free Doctor Who reference

Mulberry was a knight from Rhodes. He saved Nyssa from falling to her death in 1310. He was then transported to Virginia on 30 July 1864, with Nyssa, and met Floyd. After later travelling with the Fifth Doctor, he stopped the Daleks' plan but sacrificed his life by falling into the Time Vortex. (AUDIO: Renaissance of the Daleks)
