"Shenron can bestow any wish as long as it does not exceed the power of his creator, who must still be alive when he is summoned (i.e. Kami or Dende). He is unable to restore life to those that have died because of old age (but he can restore a person's youth), sickness or any other natural deaths. In the beginning of Dragon Ball Z, it is revealed that Shenron cannot grant the same wish more than once (e.g. bringing back those from the dead that have been killed before, etc.) and he also cannot grant a wish to defeat or kill a living being that surpasses the power of his creator. This means that the Dragon can't kill an enemy that Kami or Dende themselves are incapable of killing." Dende isn't stronger than the strongest in the universe, am I right?
