I don't really know specifically what you are asking, but well, Armaldo is the last evolution of a Anorith, which you can revive from a Claw Fossil.
you need to trade from ruby,sapphire or emerald
No, Rayquaza cannot evolve in Ruby, or any other version.
You have to go to the Mirage Tower and pick the claw fossil. One person will revive it. Get out and then go back in to get your Anorith. Level it to 40 to get your Armaldo. If you chose the other fossil and you have pokemon sapphire or ruby, you can't get it. Sorry.
Level 25.
Lvl. 25.
Metagross, Armaldo, Skarmory, Cradily, Aggron, Claydol.
if you have a pikachu,put a thunderstone on it and it will evolve into raichu
Weepinbell, Gloom and Exeggcute.
Corsola is one of the few Pokemon that doesn't have an evolution.
Silcoon will evolve at a low level because bug Pokemon evolve quickly.
try around level 33
Pokemon ruby's version IS Pokemon ruby.
