At what level does Dratini evolve?

Dratini has two evolutions. The first one happens at level 30, when it evolves into Dragonair. The second evolution happens at level 50, when Dragonair evolves into Dragonite.

Dratini starts off as just a dragon-type Pokémon. However, once it reaches the final stage of its evolution, it gains the flying type and access to several flying-type moves, such as Wing Attack at level 55 and Hurricane at level 81. Along its evolution line, Dratini's base attack, defense and hit points increase dramatically. Also, Dratini's special attack stat sees a notable increase, and it has several moves that use the special attack stat to calculate damage.
