That is up to you. Legendary Pokemon are not always the strongest. They have weaknesses like every Pokemon does. Choose a Pokemon with three evolutions, evolve it to it's final level, but make sure you don't rush. Some moves are easier to get by slow evolution. No Pokemon is all-powerful. But they can be powerful, except when going up against a higher level of a type it is weak to. By choosing moves that the type it is weak against is weak to, you have a better chance of winning.
No Arceus is one of the best Pokemon exept from Pokemon indigo(online game)
In department stroe or in team aqua hideout
None-Exept Meowith but it is more like a cat.
