They've always been Golion, Dairugger and Daltanious to me, really. I don't think I ever watched a single episode of Voltron - grew up on Dungeons and Dragons, Masters of the Universe and Thundercats. I never did watch Golion or Dairugger XV either, but I remember getting a Golion and Dairugger XV robot for my 10th or 11th birthday, so I've always referred to them as that. They've just released a new Daltanious in the toy shops, and I stood there in the aisle holding the box in my hands and staring at it for what must have been an eternity, feeling 30 years younger...
Was really expensive just for nostalgia, though, so I didn't buy it. I'll probably cave in some day.
