Brox (Nowhere Man)

Brox was a space traveller who spent a hundred years in his spaceship, the Warm Welcome, seeking out new alien life. Unfortunately, he was travelling around the least populated area, the outer-rim of the universe. After all the travelling the engines on his spaceship began to wear out, leaving mini-wormholes which reached to the other side of the universe. The Eleventh Doctor and Amy Pond travelled through the wormholes to find Brox, being the first aliens he met. The Doctor created a large enough wormhole to transport the Warm Welcome to the other side of the universe, where he continued to explore. (DWA: Nowhere Man)
