Rare Medals are powered by Spiral Energy.
- In the show, Medabots with Rare Medals are able to summon a powerful energy source called the Meda-Force. The Meda-Force is usually summoned when the Medabot's will is pushed to the limit and then suddenly forms a powerful atack of pure energy. While in Gurren Lagann, the protagonists' will and courage creates an energy source called Spiral Energy which activates the robot.
Sumilidon was the first Medabot to create artificial Meda-Force.
- As the show states, only Medabots with Rare Medals can summon the Meda-Force. As the show progressed, Sumilidon's will somehow created a form of energy that came from his medal. He uses this energy to create an attack that defeated his oppponent. And thus, Artificial Meda-Force was born.
Zuru's father built the Robo Emperor prototype the Ruber Robo Gang had.
- We know that Robo Emperor that Sea Slug used against Rokusho was the prototype that was too powerful to be sold. We also know that Zuru's father split with Dr. Akki, at least in part, because they disagreed with how powerful Medabots could be, leading him to create Kilobots such as Red Run and Gryphon. It would make sense therefore that Zuru's father built Robo Emperor, possibly even that it was an argument over him that caused Zuru's father to quit.
Sea Slug was originally put in charge as a fall guy.
- Early on in the show Sea Slug thought he was the leader of the Rubber-Robo Gang. Dr. Meta-Evil put him there in case the whole gang was ever arrested, that way Sea Slug would be fingered as the supreme leader, allowing the Doctor to continue operating in the shadows. After Sea Slug proved to be too much of a failure, Shrimplips got "promoted" to the position.
