Abra evolves at level 16 into Kadabra. In addition to that, this line of Pokémon has two other evolutions. It evolves into Alakazam once a Kadabra is traded to another trainer, and also evolves into Mega Alakazam if a Mega Stone is used.
Throughout all of its evolutions, Abra retains its psychic type. This allows it to learn powerful psychic moves, such as Psybeam and Recover. Abra's base stats also rise substantially with each evolution. In particular, its special attack stat grows very fast, which is helpful since most of Abra's attacks use the special attack stat. Its speed is also increased a great deal with each evolution, making Abra and its evolutions powerful Pokémon to train.
