this is impossible without cheating, even with cheating it may not be possible.
There is a secret path in the Pokemon League and you have to follow it to get to him.
You have to get the Member's Card (via Nintendo Event or an Action Replay) and then go to the inn at Canalave City. You'll have a dream, you'll be on New Moon Island. you cannot leave the island until Darkrai is caught or defeated. Follow the stairs to a lake and Darkrai will be there waiting for you.

u might look it up on google or get a gameshark/actionreplay
you have to follow it on your Pokemon watch and it will pop out near it's Pokemon sign
You have to be linked with them with Nintendo wireless (not wi-fi) then when your both underground just follow them or look around till you find their secret base.
Yes, you can have your Pokemon follow you in Pokemon Heart Gold, Soul Silver, and the Pokemon Ranger games. Also, certain Pokemon can follow you in Amity Square in Diamond and Pearl. (Amity Square is in Hearthome)
You have Members Card? You are lucky! Anyway, with Members Card, you can access the locked house in Canalave City, behind the Pokemon Center. When you manage to get in there, there will be a man. A man that will tuck you in a bed. When you sleep in that bed, you will appear on an island. An island called New Moon Island. Just follow the road, don't leave the island, and you will reach a special room in the island. In that room, the legendary Pokemon Darkrai will be waiting to battle you. You will encounter Darkrai in level 40 but... Darkrai's capture rate is 3%, which means that you'll have a hard time catching it. If you have a Master Ball, there's no problem! Good luck finding and catching your Darkrai! Hope I helped :)

Answer By: PokeHelp 101 First, you have to finish story mode. Once you have, just follow your regular adventure routine. Eventually, you will get a dream. Follow the story, and eventually, you will be able to recruit Darkrai. This answer has been used in words cautiously, to avoid spoilers.
If you mean they will be behind you throughout the game, then no, they won't. The only games that allowed Pokemon to follow behind for the adventure were Pokemon HeartGold and SoulSilver. In Pokemon Diamond, Pearl, and Platinum, you can go to the Amity Square, which is connected to Hearthome City, where certain chosen Pokemon can follow you for that area, however.
Cynthia(pokemon league champion) will give it to you when you follow the team galactic grunt from Pastora City.
