Appendix:Pokémon Colosseum walkthrough/Section 7

The Under

Now you're in the main part of The Under. Place the U-Disk into the UFO. This will make the platform go up. Not forward, up. You'll arrive inside the Pyrite Town windmill. You'll get a Time Flute. You can use it on Suicune. Go back down, insert the F-Disk, and go forward to exit the Under. Leave Pyrite Town, go to the Outskirt Stand, get some more Ultra Balls. Go to the Shadow Pokémon Lab. Insert the Maingate Key and enter the lab's right door. One of the computers in this room has a Shutter Switch. Press it, and the left door will open. Save.

Shadow Pokémon Lab

Head right, down the stairs, down, left, down the stairs, and get the Elixirs. Go upstairs, up, and you'll find a Researcher who will battle you.

Researcher Myron
Level 38 Voltorb
Level 38 Voltorb

Easy as pie. He'll flee, leaving the Card Key behind. Go back through the maze and outside, then through the right door. Insert the Card Key. Follow the path, and pick up the DNA Sample. Go left, and before you can take the elevator, a Cipher Peon will challenge you.

Cipher Peon Cole
Level 37 Furret
Level 39 Remoraid
Level 41 Castform
Level 43 Shadow Aipom

Aipom shouldn't be too hard to catch. Go down the elevator when finished. Heading right, you'll meet up with another Researcher.

Researcher Odlow
Level 38 Magnemite
Level 39 Magneton
Level 39 Electrode

Still easy, just like the Researcher before him. Go up the stairs and another Researcher awaits.

Researcher Coren
Level 39 Magnemite
Level 40 Magneton
Level 40 Electrode

An exact clone of Odlow except his Pokémon are +1 levels. Beat him and on the table is the Down St. Key. Go back up the two elevators, and then navigate right and down through the hallways. Talk to the Researcher by the whiteboard.

Researcher Lethco
Level 39 Electrike
Level 39 Magnemite
Level 38 Chinchou

More pushovers. Use the Down St. Key to reach a room where a Cipher Peon will appear.

Cipher Peon Lare
Level 38 Houndour
Level 38 Nuzleaf
Level 38 Carvanha
Level 43 Shadow Murkrow

Murkrow shouldn't be too hard to catch.

Head back up the elevator if you need to heal+save. Head all the way down and left, and BAM! another Cipher Peon.

Cipher Peon Vana
Level 40 Swablu
Level 40 Zubat
Level 40 Pupitar
Level 43 Shadow Forretress

Swablu and Zubat go down easy, Pupitar goes down pretty easy, and Forretress is so-so difficulty catching. Go down the elevator, take a left, and BAM! another Cipher Peon.

Cipher Peon Lesar
Level 40 Rhyhorn
Level 40 Grovyle
Level 43 Shadow Ariados

Throughout the next few rooms, two of them will have DNA Samples. If you head right from here, you'll get a Full Restore. Go up and take a right. You'll see a few elevators, and BAM! another Cipher Peon. You'll be going right, and BAM! another Cipher Peon.

Cipher Peon Tanie
Level 38 Linoone
Level 39 Vigoroth
Level 43 Shadow Granbull

Take the rightmost elevator, and check the DNA Analyzer. A three-Pokémon password is needed. Check the three DNA samples. Remember the three Pokémon. Head to the left elevator and head left, and a Researcher awaits.

Researcher Kotan
Level 40 Magneton
Level 42 Electrode
Level 41 Ampharos

Researchers are easier than Cipher Peons, hands-down. Kotan hasn't given up yet, though. And turns on the alarm.

Cipher Peon Remil
Level 43 Swellow
Level 43 Kecleon
Level 42 Kadabra
Level 43 Shadow Vibrava

After beeting Remil, head up and enter the code from the three Pokémon. Cipher Peon Skrub wants a rematch and he's behind the door.

Cipher Peon Skrub
Level 44 Graveler
Level 42 Wobbuffet
Level 43 Clamperl
Level 41 Medicham

Instead of Medicham, you'll have a second chance to get his Hitmontop if you missed it earlier. Hardest in the Lab so far, but still easy. Head forward to face the final Cipher Admin.

Cipher Admin Ein
Level 46 Altaria
Level 48 Golbat
Level 47 Huntail
Level 47 Lanturn
Level 40 Shadow Raikou

Raikou is among the toughest to catch. If you really need to, stock up on lots and lots of Ultra Balls before this battle. All of his Pokémon are extremely strong, so be on your best guard. Just to the right is a Data ROM. You must deliver this to Nett. Head back to The Under and go all the way to Nett's house. It's a list of Shadow Pokémon, but he has to find it because it was erased. You can now head to Realgam Tower, where several Shadow Pokémon and many, many Trainers lie.
