Borusa (Arc of Infinity)

Borusa was a Time Lord who held the office of Lord President.

Biography
Sometime before the second crisis involving Omega, Borusa was inducted officially as Lord President and regenerated again. Councillor Hedin left evidence of his own crimes that made it seem that Borusa was the criminal. Borusa corrected the Time Lords, revealing Hedin's wrongdoing, and hoped that Omega would find peace after the Fifth Doctor sent him back to the antimatter universe. (TV: Arc of Infinity)

Ultimately, the sheer stress of the office of Lord President caused Borusa to regenerate into a stubborn and grandiose incarnation who sought immortality in the Tomb of Rassilon. (PROSE: The Legacy of Gallifrey, TV: The Five Doctors)

Appearance
This incarnation of Borusa was white-haired and aristocratic, (PROSE: Arc of Infinity) looking older than his previous incarnations. (TV: Arc of Infinity)
