Megallan

From Tardis Wiki, the free Doctor Who reference

The Megallans were a yellow-skinned humanoid race native to one of the planets in the Zeta Four Sector. They were assembled in the fearsome, warmongering Megallan Empire until a devastating nuclear war against Telios (which saw the death of the Megallan warlord) destroyed their planet. The Telian ambassador Dea hoped to help the survivors of both her people and the Megallans rebuild on a more peaceful basis (PROSE: K9 and the Zeta Rescue)
