Leader: Viola
Pokemon Type: Bug
The gym will be accessible after defeating Roller Skater Rinka. Before braving this gym, make sure you have pokemon with flying, fire or rock moves. If you have Fennekin, then you shouldn’t have to worry about this gym. If you have Froakie or Chespin, you should still be able to exploit the weaknesses of the trainers and gym leader by bringing in a good-leveled Torchic or Pansear.
The gym must be navigated in a web-like structure which will put you along the way of other trainers.

LV10 Surskit (bug/water)
Surskit will catch your fire-type pokemon off guard. Not only that it is a dual bug/water-type that will make your fire attacks deal normal damage, it also has water moves that can endanger your fire pokemon (if you’re fighting it at the same level). If you have Pikachu, its Thunder Shock works wonders against Surskit.
LV12 Vivillon (bug/flying)
You can exploit this pokemon’s weakness with fire again. Be careful if you’re using other types of pokemon when fighting this one. Since it has high speed and attack ratings, expect it to act first and deal considerable damage. It can also use harden to bolster its defenses. Just use fire-type moves to defeat this enemy with ease.
Rewards:
After defeating Viola, take the stairs behind her to leave the gym. Heal up your pokemon and try to leave the city to the northwest. The woman there, Alexa will give you a Exp Share. Your next destination is Lumiose City.
