At level 48.
Nothing evolves into Gible. Gible evolves into Gabite, which in turn evolves into Garchomp, one of the only non-legendary Dragon types in the Sinnoh Pokedex. It is a dual Dragon and Ground type, meaning that electric attacks don't affect it. It is a very powerful Pokemon to have in your team.
Gabite evolves into Garchomp starting at level 48. (Gible evolves into Gabite starting at level 24.) Gabite is #444 in the National Pokedex, and was introduced in the Generation IV Pokemon titles (Diamond, Pearl, and Platinum) where it could be found in Wayward Cave, in a secret area under the Cycling Road (Gible can be found here, and will need to be evolved into Gabite). In Generation VI (X and Y), Gible can be found on Route 13 and evolved, or Gabite can be found in some Dragon type Friend Safaris.
