You can't
Moltres is not in ruby only firered, leafgreen and Pokemon xd gale of darkness can get moltres.
The only way to get Moltres is changing it from LeafGreen or FireRed... I traded it, it is nicknamed Archen it is Lv. 89, it know, Fly, Flamethrower, Sky Attack, Heat Wave
you have to get 10 ruby fragments from unowns in map 15, caverns of alph. Then you go to the research lab and it will have a button to push and the ten fragments turn into a ruby shard. Then you put it on you first pokemon and you go to the caverns of alph and keep clicking on the screen until you see moltres. When you battle moltres and beat him you get moltres.
basically on version 8 of tppc go to the last map: caverns of alph and capture unowns . y? becoz they giv u eithe rough diamonds, smotth pearls , and ruby,emerald and sapphire fragments and after u get 10 ruby fragments u convert it into a shard and den u can just attach that to your starter and search the maps for a moltlres but if your higghest Pokemon lvl 200 then moltres lvl 400 and don't forget that u attach the shard to yoour STARTER. ruby shard: moltres Emerald shard: zapdos Sapphire shard:articuno
The Ruby can be found in Mount Ember; 1 island. You will need Strength To get it though. And Moltres Can be found In Mount Ember!!! So Come with many Ultra Balls Ect...
first beat elite 4 then go to the place where you find moltres there will be a cave with some rockets(team rocket)
the other guy is wrong depending if you have action replay or if your using a vba on your computer just look for gameshark code for moltres and be sure its for the right game it can mess up the game if its not the right game good luck with catching them all :D
The ruby is found in Mt. ember where you find Moltres. When you see the hiker turn right and then you'll see two rocket grunts they will make a cave you will need 60 Pokemon and I am 7 years old
nothing moltres doesn't evolve
Moltres.
The Ruby is only accessible after you talk to Celio when you have the national dex (you get it from Prof. Oak once you have 60 Pokemon and have beaten the elite four) Then as soon as you get to Mt. Ember take a right instead of going left like you would to reach moltres. There should be 2 rockets there guarding the entrance to the cave that holds the ruby.
because it is a shiny Moltres
