I think Charizard would win because Lucario is fighting and steel type and Charizard is Fire {strong against steel} and Flying {strong against fighting}
well charizard of course would win because he can just burn him and do the size bin toss and onix will faint
charizard because he can use flamethrower and do size bin toss and the winner is charizard
OBJECTION! *shakes heads like edgeworth* typical sonic fan who always want sonic wins. did you think seeing c**t on lucario fans forehead? Lucario will throw a chili dog when he got a chance then sonic gone crazy on it then lucario can kick him! HOW BOUT THAT SONIC FAN!
Blastoise...obviously
i don't know what your playing at if your a real Pokemon fan youl know that giritina and lugia are much stronger then pikachu and charizard... but actually it depends on the level oh who am i kidding ofcourse lugia and giritina would win
Lucario plz cause why? check lucario movesets and who says about normal pokemons can't beat legendary? OBJECTION! THAT IS SO WRONG!
i think charizard
OBJECTION! lucario sure win cause one of it's movesets please check a boy can slave a pokemon god. legendary? we ALL CAN BEAT IT!
Charizard flying over fighting? Charizard will win
NidoKing because he is ground/poison and lucario is steel/fight so nido will win in by a landslide! although lucario has awesome moves its not enough. you can give nido super powered moves! and nido is the best!!!!!!!
If you want a SERIOUS answer: If Lucario and Mewtwo fought as CPUs both on level 9, there is no telling who the winner would be.If you want a HILARIOUS answer:Captain Falcon would come out and FALCON.... PUNCH! both of them.Lol, if you want the real answer, lucario wouldn't fight mewtwo xD but if mewtwo fought lucario and lucario had no choice lucario would win, because of his high aura abilities,
zapdos because he is electric and charizard is flying
