The restrictions include a level restriction: in Generation I, the Pokémon can be only between level 25 and 30; in Generation IV, the Pokémon are only required to be level 30 or lower. Additionally, the combined total level of the three-Pokémon battle team must be no more than 80. Evolved Pokémon are not permitted (species that have baby Pokémon are considered evolved in Generation IV). Mythical Pokémon are also prohibited. There are also height and weight restrictions: Pokémon must have a height no more than 2 m (6'07") and a weight no more than 20 kg (44.1 lbs.) to compete.
With these restrictions, in Generation I, only 45 Pokémon are eligible to be used in the Petit Cup.
All eligible Pokémon species can be rented. All rentals are level 25, although the only way to obtain a Koffing below level 30 is by trading it from a Generation II game.

The English manual for Pokémon Yellow and the English language Fancy Cup rules in the Generation IV games state that the maximum weight for participating Pokémon is 44 lbs. However, Pokémon weighing 44.1 lbs. (20 kg) may also participate.
In English, the Virtual Console manual for Pokémon Yellow states that Pokémon must have a height less than 6'8" (2 m) and a weight less than 44.1 lbs (20 kg). However, Pokémon exactly 6'8" (2 m) or exactly 44.1 lbs (20 kg) can participate.
In Generation I, even without tradebacks from Generation II, no Pokémon is made ineligible by the level limit. All Pokémon that cannot be legitimately acquired at level 30 or below also break at least one other restriction.
