yannma does not have a pre-evolution but if you teach it ancient power and level it up to level 33 it evolves into yannmega.
Yanma evolves when it learns Ancientpower, it learns it at Level 33.
it evolves in to yanmega
yanma evolves at level 33 and teach it ancientpower and level it up while it kwons ancientpower and it evolves into yanmega
Yanma evolves as soon as it learns Ancientpower which is at Level 33.
Yanma evolves into Yanmega.To evolve it it needs to be lvl 33 and know ancient power.
Yanma evolves into Yanmega once it learns ancient power and levels up. Naturally Yanma learns ancient power at level 33.
Yanma doesn't evolve in any of the GBA games. It only evolves in Diamond, Pearl or Platinum.
I think you mean Yanma for this question. Anyway, so Yanma evolves when it learns the move: Ancientpower. It will learn that move (if you choose to, of course) at level 33. So it sort of evolves by level, then. :/
yanma evolves at lv 33 if it knows ancient power
Yanma will evolve into Yanmega once it learns Ancientpower which it learns at Level 33.
In Pokemon Diamond, Yanma is a bug and flying type of Pokemon. It evolves if you level it up while it knows ancient power.
To get Yanmega you must first evolve Yanma. Yanma only evolves once learning the move ancient power and leveling up.
