World Ripper

A world ripper is an extremely gigantic spaceship armed with small cannons and turrets on its body for both defense and offense. It has 2 giant cannons on its sides that have firepower strong enough to destroy an entire Earth-sized planet, a fair portion if Jupiter-sized, and merely craters if exceeding Jupiter-size. However, it is regarded as one of the most fearful spacecraft as most planets are Earth-sized.
