Silo was made out of spare parts from a junkyard by the Cogs. Silo resembled the robot fighters in Rocky and his classmate Jennifer's computer game. Silo shot chains from his stomach, which wrapped around the Zeo Megazord. Giant Silo used the rockets on his back to fly, pulling the Zeo Megazord into space. Giant Silo threw the Zeo Megazord toward the sun and then returned to Earth. But much to his and King Mondo's surprise, the Rangers were able to bring the Zeo Megazord back to Earth and destroy Silo.
