Vredosian
From Tardis Wiki, the free Doctor Who reference
The Vredosians were a species of humanoids with grey skin, triangular teeth and quills instead of hair.
A Vredosian had been captured by Torchwood Three, but she escaped and took a job at the Withington Hotel. She was later indirectly found because of her infestation of bedbugs, which caused an abnormal increase in bug-bites at the hotel. Owen Harper took the Vredosian into custody, but he let her go to deal with a bus crash. (PROSE: Pack Animals)
