Pokémon Grand Adventure Park is our version of Safari Zone.  It has two sections.  The first section is a wildlife preserve where Poké Balls are disabled, while the second section is an area where trainers can actively capture Pokémon.

Trainers are classed based on a variety of factors, such as how many Pokémon they possess, what species of Pokémon they possess, how many wins and losses they have, how many badges they have, tournament rankings, and so on. Trainer ranks are as follows, from lowest to highest:

Class 3
Class 2
Class 1
Class E
Class D
Class C
Class B
Class A
Class S
Class SS
Class SS+
Class Z
Class X

All new trainers start as Class 3.
A Class X trainer would require all Pokémon at Level: 100, all badges, and all tournament wins, plus a plethora of wins and hardly any losses.
