On route 111, north of the desert area and east of the fiery path, there's a guy standing in front of a tree. Talk to him and he'll give you secret power. You get more of these TMs afterwards by going to Slateport and talking to one of the guys in the market area (NOT the pokemart), I mean the bit just north of the beach.
You can go and buy it. Hidden power and secret power can be bought from a person (I don't remember where he/she is).
you can get it from somewhere....but you can also buy secret power (TM43) from the slateport market....the one on the right
in Pokemon diamond and pearl just go on your udventure and you will find it but in Pokemon sapphire,ruby it's hard to get it
Go to route 111 and watch for a big tree. There you will see a man. Talk to him and voilà! You have secret power!

Use the move secret power on it.
Secret power can make secret bases for you find a tree or bush or indent in a wall then use secret power on it and inside is a base this is a place where you can decorate and customize your own place! Also if you mix records with other ruby and sapphire and emerald games you can battle other peoples secret bases! Secret power also can inflict opponents Pokemon with poison, flinch, parlyze, sleep, and can lower stats like speed.
well they are secret bases but you need to teach one of ur Pokemon secret power(tm43), and u can get it in slateport city at the open market!(In Pokemon Sapphire).
You must find a Bagon in a secret room in the meteor falls and train it.
firstly use cut then by using secret power (its a TM)
