Tyrogue can evolve into one of three pokemon: Hitmonlee, Hitmonchan, or Hitmontop Mankey evolves into Primeape As for which is better... Personally, I choose Tyrogue. That way, you can choose which pokemon you'd eventually get based on your strategy and play-style
I forgot but i think it has to do with the stats when you reach a certain level, if none are raised i think it becomes hitmontop, if attack hitmonchan i think or hitmonlee, could be speed, i forgot but i think its based on stats when you reach a level http://www.serebii.net/pokedex-dp/236.shtml A = attack, D = defense
Yes, Tyrogue evolves into one of its three evolved forms, at Level 20, based on the difference between its Attack and Defense stats. If Attack > Defense = Hitmonlee If Attack < Defense = Hitmonchan If Attack = Defense = Hitmontop Post Merge: [time]1300069407[/time] You have to have a good grasp of EV training if you're aiming for one it's evolutions. Although... another , more expensive way, is to use the Vitamins to change it's stats accordingly when you train it.
You have to remember that those stats can change when you level up, either from EVs or the Nature of the pokemon.
