Planetary destruction is difficult. You need around 2 x 1032 J of energy to overcome Earth's gravitational binding energy, for example, so most brute force methods are hardly likely to do it. Conceivably, some form of matter-to-antimatter conversion - monopoles or Q-balls - could be used to take out a large chunk of planet via chain reaction: an initial explosion is used to turn a large chunk of rock into plasma, monopoles or Q-balls are injected to convert some of this plasma into antimatter, matter-antimatter reactions heat up more rock into plasma, which can in turn be converted...

Not everything in fictionverse physics has been written about in detail, but the Important Topics pages contain information about some things (in particular, hypermatter can be found on the hyperspace page).
