Kan-Opener is fantastic because it's such a roundabout way of completing an easy household chore - you could open a tin of beans with a small plastic can opener, or you could use a 100kg fighting robot, what's more entertaining? The spelling is a little strange, but it helped to differentiate the name from the fictional "Can Opener" in the Arenas of Destruction game which predated it, so it always had my forgiveness.
