Kolspen
From Tardis Wiki, the free Doctor Who reference
Kolspen was the leader of Unvoss. He sent flowers to Romana II as a gesture of peace between his people and the Time Lords. He was killed on Gallifrey as he flew into an echo from the future of the explosion of his spacecraft. (AUDIO: Renaissance)
He was actually a Matrix projection created by a projection of Romana III. (AUDIO: Ascension)
