The Giant Warrior Robots
The Giant Warrior Robots, known as
"Tetsujin Lobo Force" in Japan, were a royal
family that in the remote past protected the
Planet Eris against evil Giant Monsters.

They were a family of three, with the Blue
Pilot as the father, the Red Pilot as the
mother, and the Gold Pilot as the Son.

Actually, they were somewhat misnamed as
their battlesuits weren't really "robots"
capable of autonomous action, but instead
vehicles that required pilots.  The suits
themselves were based on Green Knight
technology from earlier generations.

Their series lasted for 36 episodes, each of
which essentially had the same story.

They went like this:

On Evil Planet, the evil Blue Skinned King
called on his witch to create a horrible giant
monster to attack Planet Eris.  She created a
giant monster and the King sent it to attack.

Meanwhile on Planet Eris, some quirk of fate
made it so that the Robot Pilots didn't have
access to their Robots.  For example, they
accidentally locked the keys inside them.

So the Giant Monster would rampage across
the planet destroying things until finally a
locksmith showed up, jimmied open the
Robots' cockpits, and then presented the
Royal Family with an exorbitant bill.

Then the Pilots climbed into their Robots and
we saw stock footage of them emerging from
the water to kick monster ass.

Next the Robots battled the monster, who
had the upper hand at first, until the Robots
used one of their special attacks that always
destroyed monsters easily.  Why the Robots
didn't just use this 100% effective attack at
the beginning of the fight is one of life's
eternal mysteries.

them apart.
The Blue Robot and Gold Robot had different
heads for the same reason.

For me, the highlight of the show was always when the
Red Robot got to deliver the coup de grace attack
against the Giant Monster, because her technique
almost always involved using her breasts as offensive
weapons.

Here are some of the attacks that she used throughout
the series.  Unfortunately the names of the attacks were
usually censored in the American release of the series.
