A large mechanical monster that is believed to be a massive space suit for the Metalners to travel in, since they are so small. This gives them an advantage in battle as they pilot the suit from inside the "helmet."

The Astros that Genki meets in the anime series crash-landed on Pangaea hundreds of years before and were discovered by greedy humans, who enslaved them and used their strength to their own advantage. As such, the Astros have learned to hate humans.

Etymology Edit

Its name is short for astronaut, a person who uses a specialized suit to explore outer space.
