Omega (Remembrance of the Daleks)

An incarnation of Omega, already a member of the Triumvirate, emerged from regeneration as "a huge man with wide shoulders and muscular arms" in a "definite drift from the regenerative norm", leading some Gallifreyan observers to speculate his body was a genetic memory of the dark time. At one point, he stretched out his arms in a way that made him look like a barbarian king. (PROSE: Remembrance of the Daleks)
