Golbat

Golbat is the Bat Pokémon and the evolved form of Zubat, known for its enormous gaping mouth lined with sharp fangs. It feeds on the blood of other living creatures, latching on with its hollow, straw-like teeth and drinking until it can sometimes barely fly. Active mainly at night, it relies on echolocation rather than keen eyesight, and with strong friendship it can further evolve into Crobat.

The Japanese name ゴルバット (Gorubatto) is generally understood to combine an element suggesting 'gulp' or a guttural/gobbling sound with 'bat' (バット, from the English word 'bat'). The English name 'Golbat' retains this structure, blending 'gulp' (or 'gobble') with 'bat' to evoke a blood-slurping flying mammal. Both names emphasize the creature's voracious, gulping feeding habits combined with its identity as a bat.
