If you mean evolve, get a Pokemon, eg Buizle, and get it to a high level. In Buizle's case you need to get him to level 30. But some Pokemon need to be traded to evolve. Like Kadabra, Machoke and Gravaler. But others need to hold and item and be traded like Rydon must hold the Protector and be traded to evolve and Dusklops must hold the Reaper Cloth and be traded to evolve. Then Clampearl must hold the deep sea scale or the deep sea claw to evolve. Then there are some, like Palkia, Dialga and Giratina that can not evolve. Ledgondaries are unable to evolve and you will get the odd Pokemon that can't evolve like Parchirishu and Farfeched. And Pokemon that are at their last evolvment will not evolve again, like Pidgeot, Floatzel, Roserade, Stunktank and many more.
