At this moment it all comes down to Pokemon Gen 3, what are the best Pokemon from this Generation, what abilities they should have and what are their stats.
The Generation 3 code was added to the latest update, but not yet released Pokemon Go v0.71.0. When this version releases, we can expect to see all 135 Gen 3 Pokemon and extra 73 Candy families.
I have made a research and with the help of Frocharocha, I can now present you the best 7 (Non-Legendary) Gen 3 Pokemon including their stats:
- Slaking with 5441 CP, 319 Attack, 201 Defense and 300 Stamina.
- Metagross with 3664 CP, 257 Attack, 248 Defense and 160 Stamina.
- Salamance with 3532 CP, 277 Attack, 169 Defense and 190 Stamina.
- Aggron with 3004 CP, 198 Attack, 314 Defense and 140 Stamina.
- Swampert with 2815 CP, 208 Attack, 175 Defense and 200 Stamina.
- Blaziken with 2631 CP, 240 Attack, 141 Defense and 160 Stamina.
- Sceptile with 2584 CP, 226 Attack, 180 Defense and 140 Stamina.
The release date is still unknown, but we can hope to see the Pokemon Generation 3 in Q4.
