Nuvema Town

In the beginning of the game, Professor Juniper appears and talks to you about Pokemon. Then you choose your gender and your name. You meet Cheren and Bianca, your rivals, and then you go to your room. You pick a Pokemon, and then Bianca will battle you.
If you picked Snivy, Bianca will have an Oshawott Lv. 5.
If you picked Tepig, she'll have a Snivy Lv. 5.
And if you picked Oshawott, she'll have a Tepig Lv. 5.
Keep using Tackle, as she should waste time with Leer or Tail Whip.
After the battle, you notice your room is trashed. Who cares, just battle Cheren.
If you picked Snivy, Cheren will have Tepig Lv. 5,
If you picked Tepig he'll have Oshawott Lv. 5,
and if you picked Oshawott, he'll have a Snivy Lv. 5.
Again, keep using Tackle. When you beat him, your Pokemon should grow a level.
After the battle, go downstairs. Cheren and Bianca are talking to your mom. They leave, your mom heals up your Pokemon, and gives you the Xtransceiver. She'll be able to heal your Pokemon, which will be handy during Route 1.
Head to Bianca's house, in the bottom left corner. Her dad yells at her for starting an adventure. Now, proceed to Prof. Juniper's lab. You can nickname your Pokemon, and then the Prof. gives you a Pokedex and asks you to catch lots of different Pokemon. As you leave, your mom gives you the Town Map.
Now, go and take your first steps on Route 1!
