Hello There. Well first you need an Explorer Kit. You can get it from the old man in Eterna City He lives right next to the Pokemon Center. Then you need to do things for him and he'll let you make a secret base. (You'll make it underground) But you will need a Digger Drill to use on a wall. Once there's a hole. That's your secret base. I hope I helped.
You need to steal the flag out of your friend's Secret Base underground, then go up to the PC.
Yes, yes you do.
The presidents secret base is in U.S.A the 'pentagon'.
you will need a DIGGER DRILL to create a secret base which you could obtain at any hikers underground, you need a sphere to get one. when you get one, go to the menu and go to TRAPS. then use the digger drill on the wall.................... your welcome.
You cannot fight people in your secret base.
