Percy (The Killer Weed)
From Tardis Wiki, the free Doctor Who reference
Percy was the Head Gardener of the Arboretum, a giant interstellar greenhouse of the distant future that contained an example of every kind of plant life from Earth. He was grateful for the opportunity to show Clara Oswald from Earth around and to the Doctor[which?] for preventing the Paranox Web from spreading throughout the collection. (COMIC: The Killer Weed)
