Arcturus (The Curse of Peladon)
From Tardis Wiki, the free Doctor Who reference
Arcturus was the Arcturan delegate to Peladon when it applied for membership in the Galactic Federation. He aided Hepesh in attempting to prevent Peladon from joining, secretly planning for his world to exploit the planet's mineral wealth afterwards. He attempted to kill the Third Doctor but was destroyed by the Ice Warrior Ssorg from a blast of his sonic gun, acting to defend the Doctor. (TV: The Curse of Peladon)
