Unidentified Time Lord 1 (TARDIS)

An unnamed Time Lord once traveled on the TARDIS with a second Time Lord and, after the other man died, joined Isaac. The Time Lord was clad in armor, with a mask over his face.

Biography
This Time Lord traveled on the TARDIS once with another Time Lord. The two began to explore various locations that they were transported to in the TARDIS. The second drew a crossbow and slew the first, sparking a conflict between the two. After the Time Lord revived himself, the fight lasted for several minutes until the Time Lord was able to end the other's life once and for all.

Another Time Lord, Isaac, took the dead man's place and joined this man on the TARDIS. They continued to explore and rammed their cars into one another in an open field, before starting to fight one another as the two Time Lords had done previously. The two men eventually ended their fight with one another and presumably parted ways.
