The GalacticBase Robo is the GalacticBase's giant robot form and the main robot of Commander Alvin Alien/GalacticCommander. The GalacticBase Robo is significantly larger than the Galactic Gamma Megabot. Generally, the GalacticBase Robo is designed for dealing super-sized enemy opponents or for backing up its fellow Megabots/Ultrabots in combat. It can also help deal with incoming planetary threats. The only weakness is that due to it's large size, it is an easier target due to its larger size and poor maneuverability. The final strike is "Ultra-Dynamic Buster", where it fires a huge beam from its chest plate solar panels.
Credit to everyone! Most credit goes to their owners. @crazygoatanimations for Commander Alvin Alien. It'll make it's first appearance on Episode 13. Note: What do you think what'll be the inside of the GalacticBase Robo cockpit look like? Future: There will be a sixth member will be created alongside a new mecha machine, with a super combination with the Galactic Gamma Megabot. Spoilers: In the endgame, Agent BrendaWing and her strongest Guardians hijacks the GalacticBase Robo as part of her plan to destroy the Galactic Police main force. (However, it won't be over anytime soon.)
