Backup is a fan made ability I made So when a pokemon has this ability, in the wild it will call for backup and the evolved version will appear
Pokedex entries:
Fleelim, the lime bird pokemon, a normal and flying type. Fleelims are hatched during hibernation season and are hatched in their mother's claws while flying in the air. Fleelims are very fast runners, running up to 60mph.
Rooflime, the lime bird pokemon, a physic and flying type. Rooflimes use their tails and wings to act like bushes, when a smaller pokemon are near them, they pounce on that prey. These birds can fly up to 300mph and have almost unlimited energy.
