Dragon Ball

Background Information
A manga and anime by Akira Toriyama. Contains several aliens that become planetbusters once they turn into the master race. They however lack FTL movement, leaving them tied up and bent over for the characters who have it. On the other hand, it has also been massively underestimated on many occasions.

Dragon Ball GT is a continuation of the story, but it was not created by Toriyama and contains many contradictions, making it non-canon.

Standing in the Arena
Overall the Dragon Ball series is a very powerful series but not nearly as powerful as certain people make it out to be. To briefly evaluate the power of the verse:

Part I: Town/Small mountain level+ to Multi mountain/Island level by the 23rd Budokai Arc.

Part II: Planet level+ (most likely multiple Earth-sized planets) from the last half of Part II, with the high tiers of the Buu saga reaching the small (red dwarf) star category.

Battle of the Gods: Solar system busting confirmed.
