Rob Altman's characteristics: Rob is a combination of blue and Rosso, and can use the light of Ober to attack with elements like Ober.
The characteristics of G&D polar form: the ultimate sublimator is used as a weapon with great power. We can understand the strength of G&D polar form from the perspective of killing Galatron.
So Rob can't beat G&D in an extreme state.
In addition, I'd like to give you a message. The Rob theatrical version will be opened on March 9th, and Rob (three brothers and sisters) will become stronger again, surpassing Jed's extreme form, and Jed will also appear in extreme form, as well as new monsters, new girls oteo (Chaoyang) and new dark Altman.
