Macrocosmic Augmentation
The hubris present in the name of this ability is only exceeded by the one using it.
In a grand and awe-inspiring display, the user swells his/her body with powers and grows to amazing size. Larger bodies move much slower, as the transformation requires more time, yet they are more than compensated for by the raw power produced on such a scale only the mightiest of beings can maintain for long.
Power such as this is only possessed by legendary beings such as giant celestials doing battle, forming mountains and valleys with each strike. Smaller celestials attacking larger ones in swarms that move faster than the large one can keep up with. A god growing to immense size in full glory and striking down even dinosaurs while displaying his hubris for all to see.
