Then it's too late to capture it unless you saved prior to battling it.
you dont
dont know but i do know that you can catch ditto in both
You dont :) you gotta trade it if you didnt choose it as your starter
why dont u not be lazy and catch it regularly
you cant get ekans in leafgreen only in fire red ive beaten leafgreen and got moltres articuno zapdos and mewtwo im still trying to catch suicune with a lvl 100 charizard. dude u are suppes to use a lv 50 and down no you dont have to use lv50 and down. you can use lv50 and up if you want . i am trying to catch a rikou with my lv100 blastoise. and you at the top why are you including what stuff you caught for you to look good and show off? i thought so.
ummm...you dont
you must save before you battle it and if you kill it turn the game off then on again and try catching it
i guess not except if u trade
I dont think its possible ^.- or maybee you can migrate one from leafgreen or something in the pal park
by nintendo event but i dont know when the event is hope i helped [i love pokemon]
dont catch it instead evolve rhydon into it.
get the national dex then see prof oak in eterna city he'll tell you about articuno zapdos and moltres they will run around randomly use marking map to find them but dont use fly!
