Garmylebat evolves from Battroble at Level 38 and is the final evolution of Garobat.
Garmylebat is the most distinct member of its line, appearing less like a bat and more akin to a Gargoyle, the Pokémon takes on a more ape-like body structure, its upper arms are much more muscular than its pre-evolutions and the Pokémon returns to a quadrupedal stance like its base form. The Pokémon's wings stick out from its body and it will often display its wings off to threaten and intimidate any would be attackers, its wings appear more stone-like with the stripes of its pre-evolution developing into what appear like rock layers, despite this its wings are still quite flexible and it is capable of flight.
Its face is also distinctly more stone-like in appearance, the jaw of the Pokémon has remained relatively similar to its pre-evolution although its fangs are even more prominent and the two primary canines of its lower jaw protrude upwards the most distinctly. Its snout is also more pulled back being further from its jaw than its pre-evolution. Its eyes are mostly unchanged from its pre-evolution although it has a constant scowl to its look. The Pokémon's head is also covered in an elaborate design of stone with coils, bends and jagged features of stone covering much of its face similar to Mayan statue design. The Pokémon's neck collar has a similar stone structure at the top where the fur has hardened into stone forming a large disc-like plate which is divided into nine segments. Beneath this however its collar remains mostly the same with a somewhat more ruffled look. The Pokemon's lower body is somewhat shorter relative to the rest of its body than its pre-evolution although is also quite muscular, its legs are covered in stone-like features similar to its face with its feet's claws being made of what appears to be obsidian due to the black colouration and shiny appearance.
