Q: What's the difference between Normal, Shiny, Ancient, Mystic and Dark Pokémon?
A: Normal Pokémon have no boosts, while Shinies get +25% HP, Ancients get +25% defences, Darks get +25% offences & Mystics get the possibility of scaring the opponent out of attacking.
Q: How do you get Legendary Pokémon?
A: You have to beat all of the gym leaders, elite 4s, champions and frontier brains. After that, they will start appearing on the maps, just as other Pokémon do but with a much lower chance of appearing. Using a Master Ball (£10,000 at the Pokemart) is usually a good idea as the tend to appear at high levels.
