As you enter Route 2, your Xtransceiver rings. It's Mom, checking in on you. She hangs up quickly though, and walks out of the gate from Accumula Town. She's got a gift for you — the Running Shoes! With these on, you can run around to your heart's content. She says goodbye and heads for home.
This route has three novice Trainers looking for a battle. The next city is home to the first Gym, so be sure to claim those experience points! You should aim to have your Pokémon around level 12 - 15 to be on par with the Gym Leader. Just as you are about to reach the safety of Striaton City, Bianca tracks you down for a second battle.
Striaton is a small city that boasts such facilities as the Striaton Gym and the Trainer's School. The Gym can't be challenged until Cilan, one of the leaders, returns; coincidentally, he will return as soon as you defeat Cheren at the Trainer's School. Fennel's lab is housed inside the northeastern-most building; though Fennel will be too busy to see visitors until you get the Trio Badge. A small wood-like area is located east of the city.
The Dreamyard is an old factory site just outside of the city limits. The plant is closed down, and the ruins are now a playground for Trainers. Battle the two Trainers, then speak to the second girl. After learning which starter Pokémon you chose, she is willing to give you one of her own Pokémon to keep. The Pokémon that you receive will be one of the elemental monkeys, a trio of monkeys that share the starters' type triangle of Grass, Fire, and Water. The type of monkey you receive will be able to cover your starter Pokémon's weakness. This is especially helpful when challenging the Striaton Gym.
The students here are learning the basics of being a Pokémon Trainer, like status problems and abilities. The blackboard lists all the possible status conditions that can affect a Pokémon. One student asks to quiz you, and answering the two questions correctly will earn you a Full Heal. Cheren is inside, studying the notes on the blackboard. He tells you that the Gym Leader just left for the Gym, and asks for a battle to practice using items.
After the battle, he gives you a few Oran Berries as a thank you gift. Stop by the Pokémon Center to prepare your team, and head next door to the Gym.
The Striaton Gym
Striaton City Pokémon Gym Leader: --- Triple Trouble!
The Striaton Gym is designed as a restaurant, with tables and chairs in each of the four rooms. When you enter, the Gym's caretaker, Clyde, gives you a Fresh Water to help against the Gym Leader. In this Gym, you progress by stepping on the switch whose type is effective against the type shown on each curtain.
When you speak to the green-haired guy in the back, two more appear out of nowhere — one with red hair, one with blue. These three brothers are the Striaton Gym Leaders; Cilan, Chili, and Cress. However, you'll only battle one of them to earn your first Badge; your opponent depends on which starter Pokémon you chose. While your first Pokémon will be at a disadvantage, the monkey you received in the Dreamyard (either Panpour, Pansage, or Pansear) will be a definite help.
When the battle is over, your opponent will award you with the Trio Badge! He'll also give you TM83 (Work Up) as a prize for defeating him. Work Up is a handy move that raises both Attack and Special Attack at once. Don't be afraid to use it — in Generation V, every TM can be used repeatedly without breaking. With one Badge, your Pokémon will obey you up to level 20, and you also earn the ability to use the move Cut outside of battle.
When you leave the Gym, a woman approaches you and introduces herself as Fennel, a scientist who studies Pokémon Trainers. She leads you to her lab where she gives you HM01 (Cut). Then she asks for a favor; she is looking for a bit of Dream Mist that a Munna gives off. You'll need to return to the Dreamyard to find it, but speak with her roommate first. She introduces herself as Amanita, the woman who designed Unova's PC system. She quickly explains the Battle Box, a feature that allows a Trainer to register a team of Pokémon that they battle alongside the most, allowing them to be quickly exchanged as a whole with the current party.
Back to the Dreamyard
Use Cut to chop down the tree, and step through the hole in the fence. Bianca shows up, looking for Munna as well. The two of you hear a Pokémon cry out nearby, and find Munna in the warehouse ruins. Unfamiliar with humans, it tries to run, but is blocked by a pair of Team Plasma Grunts. The thugs are after the Dream Mist too, and plan to use it to manipulate people into releasing their Pokémon. They start to bully Munna, and attack you when you try to help it.
When you beat the grunts, Ghetsis shows up to scold them. The grunts remark that he is "not the Ghetsis who tries to manipulate people with his trick speeches", and they run off. Musharna lets its illusion disappear, and emerges from the shadows to comfort Munna. The two float away, leaving the Dream Mist behind. Fennel shows up right away and takes the mist back to her lab.
Collect the items here, and hunt for new Pokémon if you wish. Now that you have a Badge, you may occasionally discover unusual activity across the region, like rustling grass. This lets you encounter rarer species, like Musharna. Audino is the most common and gives a lot of experience upon defeat, making it a great way to train your Pokémon.
When you return to her lab, Fennel rewards you with the C-Gear. This device appears on the Touch Screen, and offers three means of communication: Wireless, Infrared, and Online. It lets you interact with other players, as well as access the Entralink and the Dream World. As thanks for helping Fennel, Amanita gives you the Pal Pad, which lets you interact with friends over Wi-Fi.
Now that all of that is done, you are free to head north to Route 3.
