BIG BEN

Big Ben was a shape-shifting alien that had taken on the guise of Lord Benjamin Charterhouse Fortescue. As Big Ben, Fortescue fought crime from a headquarters in the Westminster clock tower, which he accessed via a secret lift in the House of Lords, with the assistance of valet Fosdyke and assistant Tanya.
The character was created by Dez Skinn before 1982 in the British comic "Warrior."
