In case of conquest of Earth and the Federation by a hostile alien power, Captain Robau is authorized by Starfleet to unleash devastation across the galaxy. This includes, but is not limited to:
Making stars go supernova by ripping them apart with his bare hands, inducing ice ages on planets by giving them an icy Robau Stare, generating super massive black holes that swallow up entire systems by helicoptering his genitalia, and purging the galaxy of all sentient life in general.
Basically it would be like a Halo activation event only far more destructive and way more badass.
