The wave generator reached its full charge and the Doctor aimed and fired. Not really fair to call it aiming, as his target was the size of an office building.
Others were helping now. The residents of the City were coming out in force to stave off annihilation. The Doctor needed to be cautious, it would not serve the cause blasting one of those trying to help out of the sky.
"Damn.. too many people, too much risk of hitting someone..."
Plan B it was.
The TARDIS rose into the air over the City, it began a run past the monster, harassing with a blast of sonic energy right at the creature's head.
The TARDIS hung in the air about 800 yards from Godzilla, building another charge. The ship had flown through a barrage of nuclear weapons, so a lizard was not likely going to take it down.
