Each Pokemon has its own set of good and bad characteristics. But, in my opinion, Rayquaza is your best bet. This Pokemon's attack and special attack powers are outstanding. It's defense is good. It's speed is on the better side. Its worst statistic is its special defense, being mediocre, but since Rayquaza is a Dragon/Flying type Pokemon, most special attacks aren't very effective against it, besides the Ice type. Stop and think about it. Grass: not very effective. Water: not very effective. Same with Fire. Electric type moves are neither super effective or not very effective, due to Rayquaza's Dragon side.
My advice to you readers is to give special care to Rayquaza, because, in my experience, this is your best bet in a Pokemon.
Rayquaza or Kyogyre

The best Pokemon in sapphire is Treeko. Treeko is good at attacking as well as defense. It is best to have one that is good on both sides instead of just one.
the best cheat is the shiny Pokemon all the time one
