I don't know that much about the anime Dai-Guard (or Dai Guard, or even "Di Guard"), but something tells me I'd like to know more.
That something is this video.
Some people actually call Dai-Guard a "real robot" (i.e. a non-super robot mecha) disguised as a super robot, and even say it's more realistic than most "real robots." That last bit might be an exaggeration, but from what I've heard, it's not much of one.
