No. You can get one in Pokemon Mystery Dungeon: Explorers of Time after you recruit Riolu.
you can't he's not in this game
You don't battle, or even see Lucario. However, there is a Rescue Rank named after him, and Alakazam will mention Lucario when you speak to him.
no but u can get lucario rank with 15000 rescue points
You don't? Lucario isn't a usable Pokemon in Blue?
Lucario rank
50,000
yes i think so.
LUCARIO...veronica
that's just a rumar; u cant really get lucario in red/blue rescue
no, red rescue team has no 4th generation Pokemon available but some Pokemon have minor appearances: munchlax, lucario, bonsly, weavile, mime jr.
NO! Lucario is only in the sinnoh pokedex, so it is impossible to get a lucario in red rescue team! actually, you get lucario as a statue in front of your team base when you earn at least fifteen thousand rescue points. by RACERS
Its... LUCARIO!! Who else could It be?! Also the last rank is named Rucario ( lucario in japaniese)
