Pokémon Crystal Version
Pokémon Crystal Version allowed players to play as either a boy or girl for the first time. Each comes with a distinctive Poké Pack and PokéGear and even receives different phone calls. If you're an experienced player, you'll be eager to strike out for the all-new Battle Tower near Olivine City. Here you can take on waves of Pokémon Trainers, each with teams of Pokémon set at specific levels. You can win valuable items - but first you'll have to prove your battling skill! Locations and frequencies of wild Pokémon have changed greatly from Gold and Silver.
You'll also notice subtle changes in level-up abilities for some Pokémon, especially Suicune. Hot new radio personality Buena gives you the chance to collect great items - but you'll have to drop by the Radio Tower nightly. If you register another Trainer's phone number, they just might call and offer you a rare stone.
Your knowledge of Pokémon is put to the test in Blackthorn City, where Gym Leader Clair sends you to the Dragon's Den to take the Trainer Challenge. In the Tin Tower, just north of Ecruteak City, you'll encounter the Wise Trio. After this group of elders tells you of a mystical Clear Bell and the legend of the area's two towers, they'll test you in a Pokémon battle.
Two new types of Pokémon: Dark and Steel. Pokémon can carry items that boost certain abilities or have healing properties.
In addition, Pokemon Crystal Version is also compatible with the Time Capsule function, allowing players to Link Trade Pokémon between the Virtual Console versions of Pokemon Crystal Version, Pokémon Gold Version, Pokémon Silver Version, Pokémon Red Version, Pokémon Blue Version, or Pokémon Yellow Version: Special Pikachu Edition Pokémon Centres within the games.
