The strongest Pokemon Sapphire in the safari zone are Heracross, North east, Dodrio North West,Lairon North West,Pinsar North West,Pikachu North East and North west, Chansey you can find everywhare.
Wether catching a level 77 Pokemon in any game other than a legendary is possible or not, I believe the strongest Pokemon in Ruby, Sapphire and Emerald are in the tower where you catch Rayquaza. But those Pokemon are only around level 50.
i would say.... xatu and dodrio. their the only fully evolved Pokemon you can only find xatu if u have an arco bike. ( level 30 +)
Pokemon Ruby has Pokemon that Pokemon Sapphire does not and Pokemon Sapphire has Pokemon that Pokemon Ruby does not.
The strongest dragon type in pokemon Emerald, Sapphire and Ruby, is the legendary pokemon Rayquaza. In terms of non-legendary pokemon, both salamance and flygon are strong dragon types.
Arceus, the legendary Pokemon, is the strongest Pokemon ever. Search for it on the Pokemon websites pokedex to findout loads more about it. However for ruby, sapphire and emerald which you've classed your question as, rayquaza is the strongest Pokemon and it can be found on the top floor of the cave just east of that floating town. Be warned its level 70. hope that helps
There is no Pokemon mansion in sapphire.
