No one

No one is nobody's twin brother. The two are often confused with one another. No one is part of the treeko rebellion, a group of trainers who use treeko to stop the evergrowing and evil army of the mudkipz. No one is a dark and gray figure like nobody. Here's how to battle him:
1. Go to route 45 and beat all the trainers there.
2. Have a mudkip first in your party.
3. Put a treeko second in your party.
4. Find a wild pokemon. Then no one challenges you.
Here are his pokemon:
Treeko lv. 100
Grovyle lv.1337
Treeko lv. 9001
Sceptile lv. 4000
Treeko lv. 1(just hatched.)
