there is no way
No, unless you are using hacks
By fighting a lot of trainers, and wild pokemon.
Pokemon 135 (Jolteon) cannot be seen from trainers or the wild. You can, however, evolve an Eevee using a Thunderstone.
Just by using tools.
steal trainers pokemon No! This isn´t the answer! Anyone!! Is there an AR code for using legendaries in Battle Tower?
nope they stay the same lvl, hope this helps =)
Yes you can just use catch other trainers pokemon.
Yes you can by using action replay to catch your rivals starter Pokemon with the code for catching trainers Pokemon
beat up wild pokemon, gym leaders and trainers
The only way I know is using the DS action replay. They are found at Walmart for about $10. Then use the codes to be able to catch pokemon.
You must defeat wild pokemon or pokemon owned by other trainers another way to level them up is by using the item rare candy.
sadly no they had not created the sprites back then
