In order for a person to become a certified Pokemon trainer, they must first pass a written exam issued by a Pokemon Professor. The results of the test are faxed to the League's Elite 4, who grade the test and issue the requester a trainer's card.
The trainer's card allows the individual the right to take the league challenge; that is, said individual is given a pass to leave home, and not attend school (if they are still that young) while they persue their attempts at mastering the League. Once a trainer has lost to any given gym in the league, their card becomes null and void, and they are then instructed to return home. Any boxed pokemon are theirs to keep, however.
Anyone of any age may take the league's exam. There is no age limit.
If you lose to the league and wish to be reinstated, you must retake the test one year after your defeat.
The capture of Pokemon is permitted without the issue of a valid trainer's card, however, training caught Pokemon without one is strictly forbidden.
Individuals who do not have a valid's trainer's card are not permitted to buy higher grades of Pokeballs (with the exception of the Premier ball), Pokemon suppliments such as Iron and Calcium, or any X-items.
For research purposes, a region Professor may ask an individual to train a Pokemon. In such an instance, the individual is given a pass, and is allowed to train Pokemon without a valid trainer's card. However, they are strictly forbiden from killing any Pokemon, no matter what the reasoning. If a killing occurs, the individual will be jailed. Aid Pokemon (Pokemon raised from birth in the lab) are bred to be less powerful than the average Pokemon and are unable to learn moves that will cause death. However, Professors are free to capture wild Pokemon and give them to qualified (and certified) trainers as well.
The capture of Pokemon is allowed for any individuals. However, any grades of ball higher than a Pokeball (or Premier ball) are only for the use of valid card-holding trainers.
Any individual may apply for a "box system" in the Pokemon Center's PC unit. Pokemon in the PC unit are cared for around the clock by Center staff, who provide updates to trainers/owners on conditions, both mental and physical. The "box system" also includes free transportation of goods such as items, clothing, and mail throughout the region.
Trainers are highly discouraged from "mass capturing" Pokemon, that is attempting to capture all the available kinds of Pokemon in the region. This is due to a "limitations" set up by the Pokemon Center's PC dataplan. If said dataplan is overcharged, the system will crash, and may consequently destroy the data of any Pokemon in the trainer's box, thus killing them.
Trainers are encouraged to visit their boxed Pokemon at least once a month. If visitations are not logged into the system after a 60-day period, the Center staff gains the rights to the box and are under strict orders to release any abandoned Pokemon back into the wild.
Released Pokemon may become intolerable of humans, and it is highly recommended that trainers take extreme caution when releasing a Pokemon, as it may attack. It is a law to always have a Pokemon available to aid you if you plan to release a Pokemon.
If an individual wishes to release a Pokemon, but does not have a valid trainer's card, the individual must do so from the PC system, and the Center staff will take care of the release.
Only individuals with a valid trainer's card may partake in active battle.
Any trainer may battle, and it is common practice that simple eye contact is battle initiation.
Running from a battle is immediate grounds for diactivation of a trainer's card. If accused of running from battle, the individual will be banned from training Pokemon.
Losing outside of gym battles does NOT void a trainer's card.
Battles are automatically recorded through the Pokedex. Any trainer may buy or borrow a Pokedex from any region Professor. It is highly recommended that all trainers have a Pokedex.
Killing in battles is not recommended, however it is NOT illegal, if there is no intent to kill. Accidental death is proven through the recordings of the Pokedex.
Accidental death includes Pokemon killing by natural selection (a Pidgeotto killing a Rattata), critical hits (Mareep's thundershock stops the heart), and infection (poison, paralysis, burns, frostbite).
If a trainer is accused of "intent to kill", they must present the evidence through Pokedex recording. Pokedex recordings are kept on file by serial number in all regional Police Stations. Call 911 with your serial number ready, and the recording will be judged by the league's gyms and Elite 4. Any trainer found with "intent to kill" in battle will be jailed and their trainer's card will be void.
Any method of battle may be used, to include attacking the trainer (without intent to kill). Betting in battles is common practice and any form of betting, minus prositution, murder, and illegal drug exchange are allowed.
The battle rules ONLY apply to trainers who have 6 or fewer badges. If a trainer earns 7 badges, they are then qualified for the "Tamer" rule, which nulls the "intent to kill" laws. "Tamer" rules are used as the prefered method by Dragon masters, the Elite Four, and the Champion. It is highly recommended that trainers request NOT to follow "tamer" rules before battle if they do not wish to battle to death.
