Zubat is a bat Pokemon that relies on what to see?

Zubat relies on echolocation to see. It emits ultrasonic waves from its mouth and interprets the returning echoes to detect obstacles and navigate, especially in darkness.

This fits Zubat’s design and Pokédex lore: the Pokémon has no visible eyes, and its eyes are described as having atrophied or degenerated. Rather than using vision, it scans its surroundings with sound while flying through caves and other dim environments. The idea is based on real bats, many of which use ultrasonic echolocation to orient themselves and locate prey.

A common mix-up is calling the ability “sonar.” Sonar is the broader technology or method of using sound to detect objects, while echolocation is the biological process used by animals such as bats. Zubat’s Pokédex entries specifically mention ultrasonic cries or waves, making “echolocation” the clearest canonical quiz answer. Zubat is also a Poison/Flying-type Pokémon and evolves into Golbat, then Crobat, but those details are separate from how it navigates.
