"All is in readiness here on Earth. Contact home planet Zacrab and tell them we are ready for the robots."

"Zero Earth Hour" episode of Prince Planet.

Says bobbo_y_bobbo -

"Random web surfing this morning triggered early childhood memories of this very old anime that I used to watch on Channel 44.  I didn't remember the name of the show or any of the characters except the evil Warlock of Mars. Fortunately someone has posted an episode on YouTube in all its poorly-animated black and white glory.

Sit back  and enjoy the spectacle as Prince Planet battles Warlock and General Crustacean."
