PC

The PC system was created by Bill, however in in Generation III, a girl named Lanette says to have created/edited/modified it. The PC system was designed to put Pokemon that a trainer didn't have enough space for in his team. It has been seen in use in the anime, when Ash transferred his Pokemon to Prof. Oak to start a new journey into Hoenn without Charizard and the rest. It has 30 boxes in all the Pokemon games. The PC system also was used as a storage device to keep items for the trainer when they ran out of space. In the games you can also check the hall of fame in the PC system when you have defeated the Elite Four and it's champion.
