|First Appearance:||Andro Melos|
Grantechtor (グランテクター Gurantekutā) was a prototype, but more powerful, version of the Cosmo Techtor model used by Zoffy/Andro Melos. It was created by the ancient Ultra Prometheus from Ultra Super Legends.
Andro Super Warrior
The Grantechtor was created ancient scientists of the Andro group which was later hidden beneath the North Pole on Earth.
Years passed and to combat the Guar Army gigantic robots, Gyeronia, Bemzn and King Joegue, Zoffy/Andro Melos flew to the Earth to retrieve the Cosmo Techtor and used it to defeat the monster robots. With all members of Guar Army defeated, the remaining leaders, Juda, Mold and Gina had no choice but to reform into Guar. Melos quickly used the Grantechtor for the last time and defeated the decrepit villain, at the cost of the armor getting destroyed as well.
- Strength Enhancement: The Grantechtor's main ability is to enhance the user's strenth, speed and performance.
- This is so far the only known armor that was destroyed in the series' run.
