Col McConnon

Colin McConnon, universally known as "Col", was a human the Tenth Doctor and Martha Jones met on the planet Sunday in 2108.

He was one of the First Wave of eight hundred settlers on the planet. Consequently, he had to endure a cataclysmic tidal wave which killed off half the original colonists and laid waste to Sunday City, the main settlement. He became involved in the reconstruction efforts necessary to pave the way for the Second Wave.

He was Professor Ty Benson's chief assistant in her xenozoological study of Sunday. Like her, Col had a pseduo-parental relationship with Candy Kane. He regarded Chief Councillor Pallister with disdain, thinking him a mere political opportunist.
