Planet Buster Class, simply put, meant possessing the ability to destroy a planet—the combat power to stand against an entire planet alone. As far as the Victory Fleet was concerned, Xiao Ran's Dawn, Kouji Kabuto's Mazinger Z, and Ryoma Nagare's Getter Robo all possessed such capabilities.
As for Awakened Unit-01, Getter Emperor, Cruze, Graham, Basak, Luo, and Nalo, they could barely be considered capable of initially destroying a planet. However, compared to the first three, their abilities were not nearly as evident. Insufficient unit combat power, obvious limitations on their units, inadequate pilot endurance, and insufficient Pilot Level all affected, to varying degrees, their ability to become true Planet Buster Class combatants.
As for the rest of the Victory Fleet, they basically had no possibility of destroying a planet. Of course, Burning Legion and True Getter Dragon, an existence that was both a robot and a battleship, had to be excluded.
Yet even if the remaining people did not possess the ability to truly destroy a planet, when gathered together, they still possessed the strength to sweep aside all the military forces on a planet. So no matter how one looked at it, the Victory Fleet at this point truly did not lack Planet Buster Class combat power.
Of course, whether they could destroy a planet was not determined solely by whether the Victory Fleet possessed that ability. It also depended on whether the other side had combat power of the same level or higher. If the enemy possessed even greater combat power, then destroying a planet might become nothing more than a joke. But from Xiao Ran's many encounters with the Gamillas fleet, Gamillas simply did not possess combat power on their level. Aside from their numbers, they truly had no way to pose much of a threat to
