The Traveller
From Tardis Wiki, the free Doctor Who reference
The Traveller was an alien who visited other planets with his mind. His body was on Earth and he looked like a homeless man. Maxie Masters brought him cupcakes often. When he visited the Denaxian home planet, the Denaxians sent an assassin to kill him. He was protected from harm by PROBE. (PROSE: How To Appear Human In Several Uneasy Lessons)
The Traveller later visited the Ymir homeworld. He didn't realise that London was being attacked by alien forces. (PROSE: Preternatural Nights)
