1. The National Dex:
- After catching all 386 Pokemon, you unlock the National Dex. This is the complete Pokedex that includes all Pokemon from Generation III, including the Hoenn region, Kanto region, and Johto region. This allows you to catch and trade for even more Pokemon!
2. Access to New Areas:
- With the National Dex unlocked, you gain access to new areas in the Hoenn region, such as the Battle Frontier. This is a challenging area with multiple battle facilities, where you can test your skills and earn rewards.
3. More Trading Opportunities:
- With the National Dex, you have a much wider pool of Pokemon to trade with other players. You can trade for rare Pokemon, complete your National Dex, and even participate in competitive battles with a diverse team.
4. Post-Game Content:
- While the main storyline ends after defeating the Elite Four, there's still plenty to do after catching all the Pokemon. You can explore the new areas, participate in the Battle Frontier, and continue to collect and train your Pokemon.
5. A Sense of Accomplishment:
- Catching all the Pokemon in Ruby is a huge undertaking that requires dedication and time. It's a fantastic sense of accomplishment to achieve this goal!
Note: While catching all the Pokemon in Ruby is a great accomplishment, it's not technically required to complete the game. However, it opens up many exciting possibilities and allows you to truly experience the full scope of Pokemon Ruby.
