Outside-City Stand:
After that, you're back at the stand where you'll receive a mail from the children's network telling you they've recovered more data from the DataRom stolen from the lab. You receive another mail telling you to go back to Masa in Pyrite Town. You beat him and he'll tell you about spotting a trainer with a dark Bayleef (actually, this depends on which you choose at the beginning, I chose Quilava). Then you'll be able to go back to the Team Snagem building you blew up at the beginning of the game. Go there.

Next, you move to any other region and you'll receive mail telling you to see Zakoru in the JunkShop at The Under. Beat him and he'll tell you about dark Crocronaw (again, depends on your choice). You receive another mail about going to the destroyed lab. You head there.

You beat him and he'll storm off, swearing for revenge one day. You pick up the UFO disk U from his table.
Afterwards, you'll receive message about the Deep Colosseum in The Under. You head back there to compete. 4-battles per challenge again. You'll have to beat the thing 4 times (a total of 16 battles) and actually you'll battle the four Cipher Admins in the four final battles:

After that, you'll receieve a message from the childrens network telling you they've recovered data for the last dark pokemon - Togetic. You pick up the Steel Teeth from the Deep Colosseum floor, give it to the old man in front of the UFO controller, and he'll give you the UFO disk L where you can get some items.
Later, you'll receive mails from people accusing you of hurting others with a dark Togetic. After some more mails and checking news on the TV as you move from region to region, you head back to the Outside-City Stand.
Outside-City Stand:
You find your clone standing there waiting for you:
Your Clone - Armaldo, Milotic, Houndoom, Magnectric, Gyarados, Togetic (Dark 20)
Turns out he's a Cipher grunt named Fake in disguise of you. You leave the stand, comes back and he's gone.
