Yesterday's daily made me think about this, but sometimes when at the Ishtar Cliffs on Venus someone will come by with the "Ishtar Collective" mission and spawn a Cyclops. While not particularly threatening, it's kind of fun to fight. They ought to have Cyclops summon into random areas on Venus and Mars, accompanied by a contingent (Hob)Goblins of course, like the Blades of Crota do on Earth and the Moon. It'd be a fun little thing to spice up those boring patrol missions.
