Well if you want to do that then u can get the legendaries by going to zapdos which is in the power plant and find all the legendaries but there is no fast way of completing the pokedex cuz u have to catch them all to get them added to the pokedex
u could complete the pokedex
Squirtle is only obtainable if you chose it at the beginning of the game you must get one from another firered or leafgreen then give it to your firered and then you can finish your pokedex.
get the complete pokedex from prof. oak. go to the sevvi islands and do missions there. get mewto in cerulean cave. complete your pokedex.
Im pretty sure you have to beat the elite four and complete the pokedex
im pretty sure after that you'll have to complete the national pokedex
If you complete the pokedex you can get a diploma from game freak in the celadon mansion in celadon city and you can now say to everyone you did it!
If i am right you have complete your kanto(???) pokedex. I don't know if it is kanto or national.
the kanto pokedex YES national not sure but i think you have to trade from ruby or sapphire or something
look in your pokedex
To complete your Pokedex. Dunsparce does not offer much in terms of power and/or stats.
Depends on what part of the game your at if you finished complete the pokedex, get the stickers for your trainer card and try the trainer tower.
Firered and leafgreen both can catch different Pokemon but there pokedex is the same, here is some examples: magmar only in leafgreen not firered, oddish in firered not leafgreen, ekans in firered not leafgreen, bellsprout in leafgreen not firered, pinsir in leafgreen not firered.
